d31e5c1 Fix shutdown in case of errors during initialization (Wladimir J. van der Laan)
Pull request description:
PR #10286 introduced a few steps which are not robust to early shutdown in initialization.
Stumbled upon this with #11781, not sure if there are other scenarios that can trigger it, but it's good to harden against this in any case.
E.g.
```
$ src/bitcoind -debuglogfile=/dfdf
Error: Could not open debug log file /dfdf
Program received signal SIGSEGV, Segmentation fault.

c60c49b Improve help text and behavior of RPC-logging (Akio Nakamura)
Pull request description:
1. It is allowed `libevent` logging to be updated during runtime,
but still described that restriction in the help text.
So we delete these text.
2. Add a descrption about the evaluation order of `<include>` and
`<exclude>` to clarify how debug loggig categories to be set.
3. Add a description about the available logging category `"all"`
which is not explained.
4. Add `"optional"` to the help text of `<include>` and `<exclude>`.
5. Add missing new lines before `"Argument:"`.
6. `"0"`,`"1"` are allowed in both array of `<include>` and `<exclude>`.
`"0"` is **ignored** and `"1"` is treated **same as** `"all"`.
It is confusing, so forbid them.
7. It always returns all logging categories with status.
Fix the help text to match this behavior.

Add leveldb: prefix to leveldb debug logging lines.
leveldb debug messages come in various scary flavors such as:
2017-11-30 08:26:31 leveldb: Recovering log #26
2017-11-30 08:26:31 leveldb: Level-0 table #28: started
2017-11-30 08:26:31 leveldb: Level-0 table #28: 597 bytes OK
2017-11-30 08:26:31 leveldb: Delete type=0 #26
2017-11-30 08:26:31 leveldb: Delete type=3 #24
so it's reasonably important to mark them as coming from leveldb
internals and not from consensus validation wallet or such.
(this only affects `-debug=leveldb` or `-debug=1` otherwise you won't
see them in the first place)
126999d depends: fix zmq build with mingw < 4.0 (Cory Fields)

Pull request description:
Update depends ZeroMQ to 4.2.2, the release notes are available [here](https://github.com/zeromq/libzmq/releases).
We can drop both patches, as they have both been merged upstream (they actually had been for some time but just hadn't yet made it into a release).
`--without-documentation` is deprecated and has been replaced with `--without-docs`.
`--disable-perf` disables building performance measuring tools, which are enabled by default, see the libzmq [configure.ac](https://github.com/zeromq/libzmq/blob/master/configure.ac#L367).
Updated dependencies.md.
`--disable-curve-keygen` disable building the curve key generation tool. See [here](https://github.com/zeromq/libzmq/blob/master/configure.ac#L405).
Can someone on windows test that this is still working correctly. Maybe @achow101 ?

Pull request description:
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.

Instead of calling combine_logs from test_runner when the environment variable
PYTHON_DEBUG is set, add a combinedlogslen argument. This makes it easier
to call when running locally, and allows a different length of combined logs
to be printed.

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.

ConnectBlock() relies on validation that happens in ContextualCheckBlock() and
ContextualCheckBlockHeader(). This has implications for implementing consensus
changes and handling software upgrade to ensure that nodes upgrading their
software end up enforcing all the consensus rules.
A) The changes in behavior are as follows:
1. Introduce logging category "none" as alias of "0" for
both RPC-logging and bitcoind "-debug" parameter.
2. Same as "0" is given to argument of "-debug",
if "none" or "0" is given to <include>, all other given logging
categories are ignored. The same is true for <exclude>.
(Before this PR, "0" was accepted but just be ignored itself.)
B) The changes in the help text are as follows:
1. Add a descrption about the evaluation order of <include> and
<exclude> to clarify how debug loggig categories to be set.
2. Delete text that describe restriction about libevent because
it's already allowed libevent logging to be updated during runtime.
3. Add a description for category "all", "1", "none" and "0".
4. Add "optional" to the help text of <include> and <exclude>.
5. Add missing new lines before "Argument:".
6. This RPC always returns all logging categories with status.
Fix the help text to match this behavior.
c3055bb Add help-console command to Qt debug console (Luke Mlsna)
Pull request description:
This PR would close issue #9195 by adding documentation for the debug console features (mainly nested commands) which were added in [PR #7783](https://github.com/bitcoin/bitcoin/pull/7783).
The following changes were made to QT debug console code:
- Added a line to the initial message text at the top of the debug console:
> For more information on using this console type **help-console**.
- Added a pseudo-command `help-console` which is hooked after parsing the request, but before actually executing the RPC thread. It prints the following text to the console as if it were a valid RPC response.
> This console accepts RPC commands using the standard syntax.
> example: getblockhash 8
> This console can also accept RPC commands using bracketed syntax.
> example: getblockhash(8)
> A space or a comma can be used to separate arguments for either syntax.
> example: sendtoaddress \<address\> \<amount\>
> sendtoaddress,\<address\>,\<amount\>
> Commands may be nested when specified with the bracketed syntax.
> example: getblockinfo(getblockhash(0),true).
> Result values can be queried with a non-quoted string in brackets.
> example: getblock(getblockhash(0) true)[height]
This seemed like a reasonably sane way to introduce a fake RPC help command, but
