03a5dc9 [wallet] Make CWallet::FundTransaction atomic (João Barbosa)
95d4450 [wallet] Tidy up CWallet::FundTransaction (João Barbosa)
Pull request description:
This PR fixes a race for `setLockedCoins` when `lockUnspents` is true. For instance, it should not be possible to use the same unspent in concurrent `fundrawtransaction` calls.
Now the `cs_main` and `cs_wallet` locks are held during `CreateTransaction` and `LockCoin`(s). Also added some style nits around the change.

fbf327b Minimal code changes to allow msvc compilation. (Aaron Clauson)
Pull request description:
These changes are required to allow the Bitcoin source to build with Microsoft's C++ compiler (#11562 is also required).
I looked around for a better place for the typedef of ssize_t which is in random.h. The best candidate looks like src/compat.h but I figured including that header in random.h is a bigger change than the typedef. Note that the same typedef is in at least two other places including the OpenSSL and Berkeley DB headers so some of the Bitcoin code already picks it up.

Requirement for #11227.
We'll need to create sockets and perform the actual connect in separate steps, so break them up.

Remove includes in .cpp files for things the corresponding .h file already included.
Example case:
* `addrdb.cpp` includes `addrdb.h` and `fs.h`
* `addrdb.h` includes `fs.h`
Then remove the direct inclusion of `fs.h` in `addrman.cpp` and rely on the indirect inclusion of `fs.h` via the included `addrdb.h`.
In line with the header include guideline (see #10575).

93a34cf Make DisconnectBlock unaware of where undo data resides on disk (Matt Corallo)
Pull request description:
CChainState should eventually, essentially, be our exposed "libconsensus", but we're probably a few releases away, so the real goal is to clarify our internal interfaces. The main split was a big step, but validation.cpp is still a somewhat ranomly-mixed bag of functions that are pure functions which validate inputs (which should probably either merge with their callers or move into another file in consensus/), read/write data from disk, manipulate our current chain state (which moves into CChainState), and do mempool transaction validation.
Obviously this is only a small step, but some effort is made to clean up what functions the functions in CChainState call, and obviously as things are added its easy to keep clear "CChainState::* cannot call anything except via callbacks through CValidationInterface, pure functions, or disk read/write things". Right now there are some glaring violations in mempool callbacks, and general flushing logic needs cleaning up (FlushStateToDisk maybe shouldnt be called, and there should be an API towards setDirtyBlockIndex, but I'll leave that for after @sipa's current changesets land).

01013f5 Simplify tx validation tests (Pieter Wuille)
2dd6f80 Add a test that all flags are softforks (Pieter Wuille)
2851b77 Make all script verification flags softforks (Pieter Wuille)
Pull request description:
This change makes `SCRIPT_VERIFY_UPGRADABLE_NOPS` not apply to `OP_CHECKLOCKTIMEVERIFY` and `OP_CHECKSEQUENCEVERIFY`. This is a no-op as `UPGRADABLE_NOPS` is only set for mempool transactions, and those always have `SCRIPT_VERIFY_CHECKLOCKTIMEVERIFY` and `SCRIPT_VERIFY_CHECKSEQUENCEVERIFY` set as well. The advantage is that setting more flags now always results in a reduction in acceptable scripts (=softfork).
This results in a nice and testable property for validation, for which a new test is added.
This also means that the introduction of a new definition for a NOP or witness version will likely need the following procedure (example OP_NOP8 here)
* Remove OP_NOP8 from being affected by `SCRIPT_VERIFY_DISCOURAGE_UPGRADABLE_NOPS`.
* Add a `SCRIPT_VERIFY_DISCOURAGE_NOP8`, which only applies to `OP_NOP8`.
* Add a `SCRIPT_VERIFY_NOP8` which implements the new consensus logic.
* Before activation, add `SCRIPT_VERIFY_DISCOURAGE_NOP8` to the mempool flags.
* After activation, add `SCRIPT_VERIFY_NOP8` to both the mempool and consensus flags.

- Factor out some common code.
- Revert #11448 because this proves a more robust replacement, it is no longer necessary and didn't generally solve the issue.
No attempt is made to do full sanity checking on the proxy, so it can still be rejected by the core with an InitError message.

If a custom data directory is specified using `-datadir` argument, its existence is checked before the conf file is loaded. But if the conf file then specifies a different non-existent `datadir`, that isn't tested, and results in esoteric errors like:
EXCEPTION: N5boost10filesystem16filesystem_errorE
boost::filesystem::space: Operation not permitted
This just adds a check for the datadir existence at the end of `ReadConfigFile()`

Pull request description:
[Reviewer hint: use [?w=1](https://github.com/bitcoin/bitcoin/pull/10275/files?w=1) to avoid seeing a bunch of indentation changes.]
Presuming a user knows the block hash of the block containing a given transaction, this PR allows them to fetch the raw transaction, even without `-txindex`. It also enables support for getting transactions that are in orphaned blocks.
Note that supplying a block hash will override mempool and txindex support in `GetTransaction`. The rationale behind this is that a transaction may be in multiple places (orphaned blocks) and if the user supplies an explicit block hash it should be adhered to.
```Bash
$ # a41.. is a tx inside an orphan block ..3c6f.. -- first try getting it normally

Pull request description:
This patch adds an option to configure the name and/or directory of the debug log file.
The user can specify either a relative path, in which case the path is relative to the (network specific) data directory. They can also specify an absolute path to put the log anywhere else in the file system.
Alternative to #11741 that gets rid of the concept of a "log directory" by specifying the path for the specific kind of log, the debug log. Which happens to be the only kind of log we have at this point*, but a hypothetical new kind of log (say, an audit log) would get a new option. This has more flexibility than specifying a directory which has to contain all of them.
\* excluding `db.log` which is internally generated by the wallet database library, but that one moves along with `-walletdir`.
