Pull request description:
Requirement for #11227.
We'll need to create sockets and perform the actual connect in separate steps, so break them up.
#11227 adds an RAII wrapper around connection attempts, as a belt-and-suspenders in case a CloseSocket is missed.

We use select in ConnectSocketDirectly, so this check needs to happen before
that.
IsSelectableSocket will not be relevant after upcoming changes to remove select.

Combining the maps was probably never a good arrangement but is more
problematic now in presence of WitnessV0ScriptHash and WitnessV0KeyHash types.

Pull request description:
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).

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.

This fixes a crash bug when opening the options dialog.
- Check the return value of split() to avoid segmentation faults due to out of bounds when the user manages to enter invalid proxy settings. This is reported resonably often.
- Move the default proxy/port to a constant instead of hardcoding magic values.
- 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
$ ./bitcoin-cli getrawtransaction a41e66ee1341aa9fb9475b98cfdc1fe1261faa56c0a49254f33065ec90f7cd79 1

error message:
No such mempool transaction. Use -txindex to enable blockchain transaction queries. Use gettransaction for wallet transactions.

6d2f277 rpcuser.py: Use 'python' not 'python2' (Henrik Jonsson)
Pull request description:
Note that `rpcuser.py` seems to handle either version when called explicitly like `python2 rpcuser.py` / `python3 rpcuser.py`. This change allows the user's `python` to be used to interpret the script.
There's not always a `python2` installed, e.g. if only Python 3.0+ is installed as `python` / `python3`, like on Arch Linux (https://github.com/hkjn/src/blob/master/bitcoin/Dockerfile#L14) but `python` is almost always present.
