Replaces #11779 . Notes from that PR:
> Currently, when a functional test fails, the debug logs are printed sequentially to the travis log. This makes debugging race conditions based on the travis log hard. Instead, all logs events should be combined and sorted by their timestamp, then appended to the travis log.

9b80fc1 Prefix leveldb debug logging (Wladimir J. van der Laan)
Pull request description:
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 is consistent with the `libevent:` prefix for libevent messages.
(this only affects `-debug=leveldb` or `-debug=1` otherwise you won't see them in the first place)

This patch adds an option to configure the name and/or directory of the
debug log.
The user can specify either a relative path, in which case the path
is relative to the data directory. They can also specify an absolute
path to put the log anywhere else in the file system.

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.

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 ?

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.

blockchain.cpp has low unit test coverage. This commit is intended
to start improving its code coverage to reasonable levels. One or more
follow up commits will complete the task that this commit is starting
(though the usefulness of this commit is not dependent upon later
commits).
Note that these tests were not written based upon a specification of how
GetDifficulty *should* work, but rather how it actually *does* work. As
a result, if there are any bugs in the current GetDifficulty
implementation, these unit tests serve to lock them in rather than
expose them.
-- Why has blockchain.cpp been modified if this is a unit testing change?
Since the existing GetDifficulty function relies on a global variable,
chainActive, it was not suitable for unit testing purposes. Both the
existing GetDifficulty function and the unit tests now call through to
a new, more modular version of GetDifficulty that can work on any chain,
not just chainActive.
-- Why does blockchain_tests.cpp directly include blockchain.cpp instead
of blockchain.h?
While the new GetDifficulty function's signature is arguably better than
the old one's, it still isn't great, and doesn't seem to warrant inclusion
as part of the blockchain.h API, especially since only test code is
directly using it. If a better way of exposing the new GetDifficulty
function to unit tests exists, please mention it and the commit will be
updated accordingly.
-- Why is the test fixture named blockchain_difficulty_tests rather than
blockchain_tests?
The Bitcoin Core policy for naming unit test files is to match the the
file under test ("blockchain" becomes "blockchain_tests"). While this
commit complies with that, blockchain.cpp is a massive file, such that
having all of the unit tests in one file will tend towards disorder.
Since there will be a lot more tests added to this file, the intention
is to divide up different types of tests into different test fixtures
within the same file.
