Pull request description:
Splitting #11774 into two parts -- this part updates the README with the proposed naming convention, and adds some checks to test_runner.py that the number of tests violating the naming convention doesn't increase too much. Idea is this part of the change should not introduce merge conflicts or require much rebasing, so reviews of the complicated bits won't become invalidated too often; while the second part will just be file renames, which will require regular rebasing and will introduce merge conflicts with pending PRs, but can be merged later, and should also be much easier to review, since it will only include relatively trivial changes.

Pull request description:
This implements a minimum viable implementation of SegWit wallet support, based on top of #11389, and includes part of the functionality from #11089.
Two new configuration options are added:
* `-addresstype`, with options `legacy`, `p2sh`, and `bech32`. It controls what kind of addresses are produced by `getnewaddress`, `getaccountaddress`, and `createmultisigaddress`.
* `-changetype`, with the same options, and by default equal to `-addresstype`, that controls what kind of change is used.
All wallet private and public keys can be used for any type of address. Support for address types dependent on different derivation paths will need a major overhaul of how our internal detection of outputs work. I expect that that will happen for a next major version.
The above also applies to imported keys, as having a distinction there but not for normal operations is a disaster for testing, and probably for comprehension of users. This has some ugly effects, like needing to associate the provided label to `importprivkey` with each style address for the corresponding key.
To deal with witness outputs requiring a corresponding redeemscript in wallet, three approaches are used:
* All SegWit addresses created through `getnewaddress` or multisig RPCs explicitly get their redeemscripts added to the wallet file. This means that downgrading after creating a witness address will work, as long as the wallet file is up to date.
* All SegWit keys in the wallet get an _implicit_ redeemscript added, without it being written to the file. This means recovery of an old backup will work, as long as you use new software.
* All keypool keys that are seen used in transactions explicitly get their redeemscripts added to the wallet files. This means that downgrading after recovering from a backup that includes a witness address will work.
These approaches correspond to solutions 3a, 1a, and 5a respectively from https://gist.github.com/sipa/125cfa1615946d0c3f3eec2ad7f250a2. As argued there, there is no full solution for dealing with the case where you both downgrade and restore a backup, so that's also not implemented.
`dumpwallet`, `importwallet`, `importmulti`, `signmessage` and `verifymessage` don't work with SegWit addresses yet. They're remaining TODOs, for this PR or a follow-up. Because of that, several tests unexpectedly run with `-addresstype=legacy` for now.

test_framework accepts a new --usecli parameter. Running the test with
this parameter will cause all RPCs to be sent through bitcoin-cli rather
than directly over http. By default, individual test cases do not
support --usecli, and self.supports_cli must be set to True in the
set_test_params method.
We can make supports_cli default to True in future once we know which
tests will fail with use_cli.
Change TestNodeCLI.__call__() to return a new instance instead of modifying the
existing instance. This way, it's possible to create different cli objects that
have their own options (for example -rpcwallet options to connect to different
wallets), and options set for a single call (`node.cli(options).method(args)`)
will no longer leak into future calls.
Add network thread_start(), network_thread_running() and
network_thread_join() utility functions in mininode.py and use
network_thread_running() in network thread assertions.

This is the final step in #11518, except for possibly renaming - for motivation, please see that PR.
If this is merged, then migrating the test framework from asyncore to asyncio should be easier (I say should because I haven't dug too deeply into what would be required).
Requesting review from @ryanofsky , since he always has good feedback on these refactor PRs, and I'd appreciate his take on this refactor. Note particularly that I've reverted the change suggested here: https://github.com/bitcoin/bitcoin/pull/11182#discussion_r148859555 . The idea, as always, is to present a simple interface to the test writer.

This commit moves the logic that sends a version message
on connection from NodeConn to NodeConnCB. NodeConn should
not be aware of the semantics or meaning of the P2P payloads.
This makes NodeConnCB a subclass of NodeConn, and
removes the need for the client code to know
anything about the implementation details of NodeConnCB.
NodeConn can now be swapped out for any other implementation
of a low-level connection without changing client code.

Pull request description:
Closes#11348
Adds a `-walletdir` parameter which specifies a directory to use for wallets, allowing them to be stored separately from the 'main' data directory. Creates a new `wallets/` directory in datadir if this is the first time running, and defaults to using it if it exists.
Includes tests and release notes. Things which might need to be considered more:
- there is no 'lock' on the wallets directory, which might be needed?
- because this uses a new wallets/ directory by default, downgrading to an earlier version won't see the wallets in that directory (not a big deal though, users can just copy them up to the main dir)
- jnewbery suggested putting each wallet in its own directory, which is a good idea, but out of scope for this PR IMO. EDIT: this is being done in https://github.com/bitcoin/bitcoin/pull/11687
- doc/files.md needs updating (will do soon)
I also considered including a cleanup by removing caching of data directory paths and instead just initialise them once on startup (c.f. #3073), but decided it wasn't super relevant here will just complicate review.

The mininode module includes code to support p2p versions below
60001. However, the test_framework does not support versions
of Bitcoin Core before V0.13.0. Remove code supporting
p2p versions before 60001 (which has never been run).
BIP31 support was added to Bitcoin Core in version 0.6.1. Our test
framework is incompatible with Bitcoin Core versions that old, so remove
all special logic for handling pre-BIP31 pings.
p2p connections can now be added to TestNode instances.
This commit also updates the example test to use the new
p2p interface in TestNode to demonstrate usage.
A future commit will update the existing tests to use p2p through the
TestNode.

Pull request description:
Sending a getheaders message with an empty locator and a stop hash is a request for a single header by hash. The node will respond with headers for blocks not in the main chain as well as those in the main chain. To avoid fingerprinting, the node should, however, ignore requests for headers on side branches that are too old. This replicates the logic that currently exists for `getdata` requests for blocks.

Split off AuthServiceProxy.get_request method to make it easier to batch RPC

This does not change any existing behavior.
Change AuthServiceProxyWrapper.__getattr__ to only wrap proxied attributes, not
real attributes. This way AuthServiceProxyWrapper can continue logging RPC

a7820422e qa: Treat mininode p2p exceptions as fatal (Suhas Daftuar)
Pull request description:
#11121 inadvertently broke the constructor for the `TestNode()` object in `p2p-segwit.py`, silently breaking at least one of the tests.
Although the python code was raising exceptions due to a `TestNode()` object not existing (or having the right type), mininode was masking these from anyone running the test through the test_runner (like travis), because it catches all exceptions during message delivery and just prints a log message and continues. Such "graceful" handling of errors is almost certainly something we don't want in our test suite, so the first commit here attempts to prevent that type of failure from ever being masked.
The second commit fixes the particular bug in `p2p-segwit.py`.

0063d2c3d [tests] Make p2p-leaktests.py more robust (John Newbery)
Pull request description:
There has been an example of p2p-leaktests.py failing on travis in the new service bits test (introduced in #11001 . It appeared to me that the previous p2p connections had not been fully disconnected before attempting to add new p2p connections.
I've added a sleep and restarted the NetworkThread, but I don't know whether this will fix the problem, since I'm unable to reproduce the failure locally.
@MarcoFalke - not sure what you want to do here? I don't think this change could make things any worse.

be2a2ab6a [tests] fix - use rpc_timeout as rpc timeout (John Newbery)
Pull request description:
Some additional tidyups after the introduction of TestNode:
- commit 1 makes TestNode use the correct rpc timeout. This should have been included in #11077
- commit 2 separates `add_node()` from `start_node()` as originally discussed here: https://github.com/bitcoin/bitcoin/pull/10556#discussion_r121161453 with @kallewoof . The test writer no longer needs to assign to `self.nodes` when starting/stopping nodes.
- commit 3 adds a `set_test_params()` method, so individual tests don't need to override `__init__()` and call `super().__init__()`
Tree-SHA512: 0adb030623b96675b5c29e2890ce99ccd837ed05f721d0c91b35378c5ac01b6658174aac12f1f77402e1d38b61f39b3c43b4df85c96952565dde1cda05b0db84
Almost all test scripts currently need to override the __init__()
method. When they do that they need to call into super().__init__() as
the base class does some generic initialization.
This commit makes the base class __init__() call into set_test_params()
method. Individual test cases can override set_test_params() to setup
their test parameters.
Separates the act of creating a TestNode object from starting the node.
The test_framework now keeps track of its list of TestNodes, and test
writers can call start_node() and stop_node() without having to update
the self.nodes list.
c6ec4358a [tests] Add bitcoin_cli.py test script (John Newbery)
b23549f6e [tests] add TestNodeCLI class for calling bitcoin-cli for a node (John Newbery)
Pull request description:
We don't test bitcoin-cli at all. That means that we can miss inconsistencies between the bitcoin-cli client and the RPC interface, such as #10698 and #10747. It also means that the various bitcoin-cli options and features are untested and regressions could be silently introduced.
Let's fix that.
This PR adds bitcoin-cli testing in the python functional test_framework:
1. Add a bitcoin_cli.py test script that tests bitcoin-cli. At the moment it only tests that the result of `getinfo` is the same if you run it as an RPC or through bitcoin-cli, but can easily be extended to test additional bitcoin-cli features
**EDIT: `--usecli` option is moved to a separate PR. This PR now only covers the bitcoin_cli.py test.**
2. ~Add a `--usecli` option to the test framework. This changes the test to use bitcoin-cli for all RPC calls instead of using direct HTTP requests. This is somewhat experimental. It works for most tests, but there are some cases where it can't work transparently because:~
- ~the testcase is asserting on a specific error code, and bitcoin-cli returns a different error code from the direct RPC~
- ~we're sending a very large RPC request (eg `submitblock`) and it can't be serialized into a shell bitcoin-cli call.~
~I think that even though `--usecli` doesn't work on all tests, it's still a useful experimental feature. Future potential enhancements:~
- ~enhance the framework to automatically skip tests that are known to fail with bitcoin-cli if the `--usecli` option is used.~
- ~run a subset of tests in Travis with `-usecli`~
This builds on and requires the `TestNode` PR #10711 . As an aside, this is a good demonstration of how tidy it is to add additional features/interfaces now that test node logic/state is encapsulated in a TestNode class.
Addresses #10791

08ce33f8e qa: Move wait_until to util (MarcoFalke)
Pull request description:
This moves `wait_until` to `util.py` to make it generally available to python tests.
Also, `wait_until` now takes an optional lock that is acquired while testing the predicate.
Previously the lock was always acquired, even when it was not necessary, cf. `disconnect_ban.py`.

Fixes a couple of bugs from the introduction of TestNode:
- test scripts were no longer able to specify a custom timeout for
starting a node. Therefore tests with nodes that take a long time to
start up (eg pruning.py) would fail.
- the test for whether a node has failed on start up was broken
by changing 'assert x is None' to 'assert not x'. Since
subprocess.poll() can return None (indicating the node is still running)
or 0 (indicating the node exited with return code 0), this was a
regression.
When running the tests locally with a parallelism of 4 on an otherwise
busy system, RPC can take quite a wait to come up.
Change the timeout to 60 seconds just to be safe.
TestNode is a class responsible for all state related to a bitcoind node
under test. It stores local state, is responsible for tracking the
bitcoind process and delegates unrecognised messages to the RPC
connection.
This commit changes start_nodes and stop_nodes to start and stop the
bitcoind nodes in parallel, making test setup and teardown much faster.
cc5d38f4b Add option to attach a python debugger if test fails (John Newbery)
Pull request description:
Adds a simple option to the test_framework to attach pdb if the test fails.
Helpful for catching and debugging intermittent failures: Run the test in a loop with this option. The first failure will cause execution to pause and nodes will be left running for interactive debugging.

In v0.15, we disconnect nodes that send us version messages with
unsupported service bits (1 << 5 and 1 << 7). This commit adds a test
that bitcoind will disconnect those nodes before August 1st 2018, and won't
disconnect those nodes after August 1st 2018.
