Pull request description:

  Next step in #10603.

  - first three commits tidy up feature_block.py
  - fourth commit removes usage of ComparisonTestFramework

  Longer term, it would be better to separate net_processing testing from validation testing, but I think this is still a useful PR, since it moves us away from the comparison test framework.

Merge #12076: qa: Use node.datadir instead of tmpdir in test framework
c8330d4 qa: Use node.datadir instead of tmpdir in test framework (MarcoFalke)

Pull request description:

  Commit c53c9831ee introduced the utility function `get_datadir_path`, however not all places in the code use this util function. Using the util function everywhere makes it easier to review pull requests related to the datadir.

  This commit replaces datadir path creation with the `datadir` member of `TestNode`, which itself uses `get_datadir_path`.

5812273 [Tests] Require exact match in assert_start_raises_init_eror() (John Newbery)
0ec08a6 [Tests] Move assert_start_raises_init_error method to TestNode (John Newbery)

Pull request description:

  Extracted from #12379, because the changes are important on their own.

  This allows for exact testing, since the match can be specified with a strict regex. Internal details (such as exact formatting of the error message) can still be fuzzed away by regex wildcards.

Pull request description:

  Beside removing duplicates of the same args in the code, this actually helps with debugging after a test failure.

  For example, `bitcoin-qt` has `server` turned off, so you'd have to turn it on every time, if you wanted to debug a temporary test datadir created by the test framework.
  Also, `keypool` would fill up if you forget to specify `-keypool=1`.

Those parts in `validateaddress` have been marked as deprecated. The tests have been updated to use `getaddressinfo` except the `disablewallet` test which is the only test that actually uses `validateaddress` to validate an address.

Pull request description:

  To test, make an arbitrary whitespace change to `src/bitcoind.cpp` and recompile. This normally resets the firewall's memory.

  Easiest way to reproduce a popup without running the test suite:

  - first commit changes log level for an internal log from INFO to DEBUG. (Not really related, but I started finding the INFO level logging annoying when debuging test failures)
  - second commit introduces a `P2PStub` class - a subclass of `NodeConnCB` which has its own block and tx store and responds appropriately to getdata requests. Not all the functionality is used in `invalidtxrequest.py`, but will be used in `invalidblockrequest.py` and `p2p-fullblocktest` when those are changed to use `BitcoinTestFramework`
  - third commit tidies up `invalidtxrequest.py`

ec527c6c88 Don't allow relative -walletdir paths
Also warn if bitcoind is configured to use a relative -datadir path.

Specifying paths relative to the current working directory in a daemon process
can be dangerous, because files can fail to be located even if the
configuration doesn't change, but the daemon is started up differently.

Specifying a relative -datadir now adds a warning to the debug log. It would
not be backwards-compatible to forbid relative -datadir paths entirely, and it
could also be also inconvenient for command line testing.

Specifying a relative -walletdir now results in a startup error. But since the
-walletdir option is new in 0.16.0, there should be no compatibility issues.
Another reason not to use working directory paths for -walletdir specifically
is that the default -walletdir is a "wallets" subdirectory inside the datadir,
so it could be surprising that setting -walletdir manually would choose a
directory rooted in a completely different location.

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.
