Pull request description:
This is a move-only commit. No code is changing and the moves can be easily verified with:
```sh
git log -p -n1 --color-moved=dimmed_zebra
```
This commit moves functions and variables that wallet code depends on out of libbitcoin_server.a, so the bitcoin-wallet tool can be built without libbitcoin_server.a in #15639, and attempting to access server state from wallet code will result in link errors instead of silently broken code.
List of moves:
- `CheckTransaction` moves from `consensus/tx_verify.cpp` to `consensus/tx_check.cpp`
- `urlDecode` moves from `httpserver.cpp` to `util/url.cpp`
- `TransactionErrorString` moves from `node/transaction.cpp` to `util/error.cpp`
- `StringForFeeReason` and `FeeModeFromString` move from `policy/fees.cpp` to `util/fees.cpp`
- `incrementalRelayFee` `dustRelayFee` and `nBytesPerSigOp` move from `policy/policy.cpp` to `policy/settings.cpp`
- `SignalsOptInRBF` moves from `policy/rbf.cpp` to `util/rbf.cpp`
- `fIsBareMultisigStd` moves from `validation.cpp` to `policy/settings.cpp`
- `ConstructTransaction` `TxInErrorToJSON` and `SignTransaction` move from `rpc/rawtransaction.cpp` to `rpc/rawtransaction_util.cpp`
- `RPCTypeCheck` `RPCTypeCheckArgument` `RPCTypeCheckObj` `AmountFromValue` `ParseHashV``ParseHashO` `ParseHexV` `ParseHexO` `HelpExampleCli` and `HelpExampleRpc` move from `rpc/server.cpp` to `rpc/util.cpp`
- `AmountHighWarn` and `AmountErrMsg` move from `ui_interface.cpp` to `util/error.cpp`
- `FormatStateMessage` and `strMessageMagic` move from `validation.cpp` to `util/validation.cpp`
- `VerifyWallets` `LoadWallets` `StartWallets` `FlushWallets` `StopWallets` and `UnloadWallets` move from `wallet/init.cpp` to `wallet/node.cpp`

Adds the following util units and adds them to libbitcoin_util:
- `util/url.cpp` takes `urlDecode` from `httpserver.cpp`
- `util/error.cpp` takes `TransactionErrorString` from
`node/transaction.cpp` and `AmountHighWarn` and `AmountErrMsg` from
`ui_interface.cpp`
- `util/fees.cpp` takes `StringForFeeReason` and `FeeModeFromString` from `policy/fees.cpp`
- `util/rbf.cpp` takes `SignalsOptInRBF` from `policy/rbf.cpp`
- 'util/validation.cpp` takes `FormatStateMessage` and `strMessageMagic` from 'validation.cpp`
This moves the following policy settings functions and globals to a new
src/policy/settings unit in lib_server:
- `incrementalRelayFee`
- `dustRelayFee`
- `nBytesPerSigOp`
- `fIsBareMultisigStd`
These settings are only required by the node and should not be accessed
by other libraries.
Removes the now-unused Broadcast/ResendWalletTransactions interface from
validationinterface.
The wallet_resendwallettransactions.py needs a sleep added at the start
to make sure that the rebroadcast scheduler is warmed up before the next
block is mined.

6e597001a Import all origin info in importmulti; even for non-importing pubkeys (Pieter Wuille)
9a93c91c8 Keep full pubkeys in FlatSigningProvider::origins (Pieter Wuille)
Pull request description:
This fixes#15743 and #15742.
Since #15263, pubkeys are no longer imported for non-PKH (or WPKH, or any wrapped form of those) outputs, as that would incorrectly mark outputs to single-key versions of multisig policies as watched.
As a side effect, this change also caused origin info not to be imported anymore for multisig policies.
Fix this by plumbing through the full pubkey information for origins in FlatSigningProvider, and then importing all origin info we have in `importmulti` (knowing more never hurts, and additional origin information has no negative consequences like importing the pubkeys themselves).

This commit makes the pruning.py much faster.
Key insights to do this:
- pruning.py doesn't care what kind of transactions make up the big
blocks that are pruned in the test. Instead of making blocks with
several large, expensive to construct and validate transactions,
instead make the large blocks contain a single coinbase transaction with
a huge OP_RETURN txout.
- avoid stop-starting nodes where possible.
This test could probably be made even faster by using the P2P interface
for submitting blocks instead of the submitblock RPC.

Pull request description:
Python 3.4 is EOL after March 2019, so switch to 3.5. See https://devguide.python.org/#status-of-python-branches
This pull does the following in a bunch of commits:
* scripted diff to use the `bytes::hex()` method in place of previous wrappers (`b2x`, `bytes_to_hex_str`, `hexlify`, ...)
* Update the build system (gitian and travis) to remove python2.7 and replace it with python3.5
* Another scripted-diff to remove brackets after `assert`. This is unrelated to the python3.5 switch, but a stylistic commit, so probably not worth to split up. The motivation behind it is to avoid asserting on data structures (such as tuples of length one), which never fails:
```py
>>> assert(False,) # with brackets
>>> assert False, # without brackets
SyntaxError: invalid syntax
>>> assert False # proper assertion
AssertionError
```
* And then a final scripted diff to update the copyright headers in the `test` subfolder, since I touched most of the files anyway and it wouldn't make sense to split this commit out into a separate pull.

But ```m_config_sections.clear()``` in ```ArgsManager::ReadConfigStream()``` is called every time when reading each configuration file, so it can warn about only last reading file if ```includeconf``` exists.
This PR fix lack of warning by collecting all section names by moving ```m_config_sections.clear()``` to ```ArgsManager::ReadConfigFiles()``` .
Also add a test code to confirm this situation.

Creating the `rpc_misc.py` functional test file to add space for adding tests to a file that doesn't have a lot of coverage.
- Removing the `getmemoryinfo()` smoke test from wallet basic rather than moving it to keep the wallet decoupled. Feel like testing for reasonable memory allocation values should suffice.
- Adding coverage for `mallocinfo()`. Introduced standard lib XML parser since the function exports an XML string that describes the current state of the memory-allocation implementation in the caller.

Pull request description:
This introduces a consistent notation for RPC arguments in `scantxoutset`, `importmulti`, and `deriveaddresses`, either:
* `"range" : int` to just specify the end of the range
* `"range" : [int,int]` to specify both the begin and the end of the range.
For `scantxoutset`, this is a backward compatible new feature. For the two other RPCs, it's an incompatible change, but neither of them has been in a release so far. Because of that non-released reason, this only makes sense in 0.18, in my opinion.
I suggest this as an alternative to #15496, which only makes `deriveaddresses` compatible with `importmulti`, but not with the existing `scantxoutset` RPC. I also think `[int,int]` is more convenient than `{"start":int,"stop":int}`.
I realize this is technically a feature added to `scantxoutset` after the feature freeze. If desired, I'll drop the `scantxoutset` changes.

ef362f2773 rpc/gui: Remove 'Unknown block versions being mined' warning (Wladimir J. van der Laan)
Pull request description:
Due to miners inserting garbage into the version numbers causing false positives, the current version signalling has become completely useless. This removes the "unknown block versions" warning which has the tendency to scare users unnecessarily (and might get them to "update" to something bad).
It preserves the warning in the logs. Whether this is desirable can be a point of discussion.

Should fix#14446

Due to miners inserting garbage into the version numbers, the current
version signalling has become completely useless. This removes the
"unknown block versions" warning which has the tendency to scare
users unnecessarily (and might get them to "update" to something
bad).
It preserves the warning in the logs. Whether this is desirable can
be a point of discussion.

Pull request description:
Digging into #15240 the lack of the proper logging has been discovered.
Fixed by this PR.
UPDATE (inspired by @laanwj's [comment](https://github.com/bitcoin/bitcoin/pull/15278#discussion_r252641810)):
Not being able to create the PID file is fatal now.

**Notes for reviewers**
1. `CreatePidFile()` has been moved from `util/system.cpp` to `init.cpp` for the following reasons:
- to get the ability to use `InitError()`
- now `init.cpp` contains code of both creating PID file and removing it
2. Regarding 0.18 release process: this PR modifies 1 string and introduces 2 new ones.

Pull request description:
Use ```test_framework.util.bytes_to_hex_str()``` instead of ```bytes.hex()``` that new in Python 3.5 to support minimum version of Python(test).
```test/functional/test_framework/wallet_util.py``` is also reported to have '\.hex()' in #15397,
but it does not matter because it calls CScript.hex() defined in wallet_util.py.

1. Fix lack of warning by collecting all section names by moving
m_config_sections.clear() to ArgsManager::ReadConfigFiles().
2. Add info(file name, line number) to warning message.
3. Add a test code to confirm this situation.
3. Do clear() in ReadConfigString().

b52cb63688 Add getdescriptorinfo to compute checksum (Pieter Wuille)
3b40bff988 Descriptor checksum (Pieter Wuille)
Pull request description:
This adds support for a descriptor-specific 8-character checksum.
Descriptors may optionally be suffixed with a `#` plus these 8 checksum characters. Any descriptor that contains a `#` at the end must be followed by a valid checksum. If the `#` is missing entirely, it is valid without checksum.
All RPCs are updated to report descriptors that include the checksum. On input, they are optional except in `deriveaddress` and `importmulti`, which require descriptors which include a checksum.
A new RPC is also added to analyse descriptors (`getdescriptorinfo`), which can be used to compute the checksum for a descriptor without.

7344a7b998 Implement utxoupdatepsbt RPC and tests (Andrew Chow)
Pull request description:
This PR adds 3 new utility RPCs for interacting with PSBTs.
`utxoupdatepsbt` updates a PSBT with UTXO information from the node. It only works with witness UTXOs because full transactions (as would be needed for non-witness UTXOs) are not available unless txindex is enabled.
`joinpsbts` joins the inputs from multiple distinct PSBTs into one PSBT. e.g. if PSBT 1 has inputs 1 and 2, and PSBT 2 has inputs 3 and 4, `joinpsbts` would create a new PSBT with inputs 1, 2, 3, and 4.
`analyzepsbt` analyzes a PSBT and determines the current state of it and all of its inputs, and the next step that needs to be done.
