- Change regular expression to cover recent versions, as well as
subversions with custom uacomment, and improve readability.
- Vary uptime requirements per network (onions are allowed to have less
uptime, to make sure we get enough of them)
- Add deduplication step (to allow simple concatentation of multiple seeds files).
- Log of number of nodes (per network) after every step.

977dd23e4023ac2f6cbbe86eb769db079b8018be qt: Periodic translations update (Wladimir J. van der Laan)
Pull request description:
Pull new translations from Transifex (using bitcoin-core/bitcoin-maintainer-tools#36) and run `make translate`.
(maybe the last one before the split-off)
Also added a commit to add `src/qt/locale` to the exclusions for the whitespace linter. I don't think automatically generated files should be linted.

463a1d5244337915de36db36de573eb8782bc430 Refresh ZeroMQ 4.3.1 patch (Nathan Marley)
Pull request description:
Currently in Alpine Linux (latest, 3.10) in the depends system, one of the ZeroMQ patches won't apply cleanly because the context around the patch has changed and Alpine's `patch` implementation can't handle the diff.
Some patch implementations can't handle fuzz / too much divergence from the original code.
This PR just tweaks the context code around the patch so that less-sophisticated patch implementations (such as on Alpine Linux) can apply the patch without errors.
This partially fixes #16925

568aa0cf8329293692e4249dabd94052533c050d Add OpenSSL termios fix for musl libc (Nathan Marley)
Pull request description:
Currently the version of OpenSSL included in the depends system won't build on musl based systems because `termio.h` does not exist. The proper header named `termios.h` does exist.
This PR adds a patch for OpenSSL to replace the `termio.h` header with `termios.h`, which is the proper POSIX header as I understand it.
This is a known issue as `TERMIOS` (not `TERMIO`) should be the default, and is fixed in later versions of OpenSSL. There is discussion on the OpenSSL repo here: openssl/openssl#163
This has been [fixed in OpenSSL](https://github.com/openssl/openssl/commit/64e6bf64b36136d487e2fbf907f09612e69ae911).
This partly fixes #16925 and allows building Bitcoin on Alpine using the depends system.

Pull request description:
If the hash is not `noexcept`, `unorderd_map` has to assume that it can throw an exception. Thus when rehashing care needs to be taken. libstdc++ solves this by simply caching the hash value, which increases memory of each node by 8 bytes. Adding `noexcept` prevents this caching. In my experiments with `-reindex-chainstate -stopatheight=594000`, memory usage (maximum resident set size) has decreased by 9.4% while runtime has increased by 1.6% due to additional hashing. Additionally, memusage::DynamicUsage() is now more accurate and does not underestimate.

efd2474d17098c754367b844ec646ebececc7c74 util: CBufferedFile fixes (Larry Ruane)
Pull request description:
The `CBufferedFile` object guarantees its user is able to "rewind" the data stream (that's being read from a file) up to a certain number of bytes, as specified by the user in the constructor. This guarantee is not honored due to a bug in the `SetPos` method.
Such rewinding is done in `LoadExternalBlockFile()` (currently the only user of this object), which deserializes a series of `CBlock` objects. If that function encounters something unexpected in the data stream, which is coming from a `blocks/blk00???.dat` file, it "rewinds" to an earlier position in the stream to try to get in sync again. The `CBufferedFile` object does not actually rewind its file offset; it simply repositions its internal offset, `nReadPos`, to an earlier position within the object's private buffer; this is why there's a limit to how far the user may rewind.
If `LoadExternalBlockFile()` needs to rewind (call `blkdat.SetPos()`), the stream may not be positioned as it should be, causing errors in deserialization. This need to rewind is probably rare, which is likely why this bug hasn't been noticed already. But if this object is used elsewhere in the future, this could be a serious problem, especially as, due to the nature of the bug, the `SetPos()` _sometimes_ works.
This PR adds a unit test for `CBufferedFile` that fails due to this bug. (Until now it has had no unit tests.) The unit test provides good documentation and examples for developers trying to understand `LoadExternalBlockFile()` and for future users of this object.
This PR also adds code to throw an exception from the constructor if the rewind argument is not less than the buffer size (since that doesn't make any sense).
Finally, I discovered that the object is too restrictive in one respect: When the deserialization methods call this object's `read` method, a check ensures that the number of bytes being requested is less than the size of the buffer (adjusting for the rewind size), else it throws an exception. This restriction is unnecessary; the object being deserialized can be larger than the buffer because multiple reads from disk can satisfy the request.

Pull request description:
Primarily I'd like to remove this because it is very imprecise, due to Python's dynamic nature, giving it a large list of false positives that need to be listed as exceptions. See for example #16906.
It's also a frequent source of complaints. I'm doubtful of the usefulness of checking for dead code in a linter in the first place.
Having some dead code in the test framework for a while is not a
disaster.

fadd76acc25907bd94ea759f5f2b719ebc3fd2b4 ci: Remove TRAVIS env vars (MarcoFalke)
fa449b89b51df7670248cb3504d91f93fc68e0c2 ci: Set $HOST before setting fallback values (MarcoFalke)
Pull request description:
This shouldn't change anything, except that `$HOST` is now properly set in the `$BASE_OUTDIR`. (Previously it would always use `x86_64-unknown-linux-gnu` in the directory name and now it should use the correct host)
The second commit removes travis environment variables in the `ci` system. Also, shouldn't change any behavior.

Primarily I'd like to remove this because it is very imprecise, due to
Python's dynamic nature, giving it a large list of false positives that
need to be listed as exceptions. See for example #16906.
It's also a frequent source of complaints. I'm doubtful of the
usefulness of checking for dead code in a linter in the first place.
Having some dead code in the test framework for a while is not a
disaster.

dbdc758c27cfdda9d255742b6c6ff4d1b7be82df doc: Improve doxygen readme navigation section (Jon Layton)
c15ac2c0aa45c59aee6d36c2d6d5210290dc601c doc: Move doxygen intro to file for USE_MDFILE_AS_MANPAGE (Jon Layton)
Pull request description:
With `USE_MDFILE_AS_MAINPAGE`, this moves the introductory Doxygen comment to its own file. This makes `bitcoind.cpp` cleaner.
It also removes the `\mainpage` header text, which was smaller than the section titles, and improves the Navigation section.

faa079db92e614bddfe8bd323ddcd2adb77e0961 travis: Disable feature_block in tsan run (MarcoFalke)
Pull request description:
The `feature_block` test causes the travis machine to OOM, when run with the thread sanitizer.
The stderr says:
```
==27237==ERROR: ThreadSanitizer failed to allocate 0xf6000 (1007616) bytes of LargeMmapAllocator (error code: 12)
...
FATAL: ThreadSanitizer CHECK failed: /build/llvm-toolchain-3.8-_PD09B/llvm-toolchain-3.8-3.8/projects/compiler-rt/lib/sanitizer_common/sanitizer_common.cc:183 "((0 && "unable to mmap")) != (0)" (0x0, 0x0)
ERROR: Failed to mmap
```
(from https://travis-ci.org/bitcoin/bitcoin/jobs/588194563#L10505)
Fix this by disabling `feature_block` on travis. Longer term, I'd like to move away from travis, but I'll leave this for a follow-up.

6170ec5d3ac2bc206068b270e5722a7ecd3a8f26 Do not query all DNS seed at once (Pieter Wuille)
Pull request description:
Before this PR, when we don't have enough connections after 11 seconds, we proceed to query all DNS seeds in a fixed order, loading responses from all of them.
Change this to to only query three randomly-selected DNS seed. If 11 seconds later we still don't have enough connections, try again with another one, and so on.
This reduces the amount of information DNS seeds can observe about the requesters by spreading the load over all of them.

utACK 6170ec5d3ac2bc206068b270e5722a7ecd3a8f26 - I think the risk of a single seeder codebase is orthogonal to this PR. Such risks could also be interpreted differently (diversity could also increase the risk based on the threat model).
fanquake:
ACK 6170ec5d3ac2bc206068b270e5722a7ecd3a8f26 - Agree with the reasoning behind the change. Did some testing with and without `-forcednsseed` and/or a `peers.dat` and monitored the DNS activity.

fa69588537bc91c0aedbc89ef1760d89cbffad75 test: Make PORT_MIN in test runner configurable (MarcoFalke)
Pull request description:
This is needed when some ports in the port range are used by other processes. Note that simply assigning the ports dynamically does not work:
* We spin up several nodes per test (each node gets its own port)
* We run several tests in parallel
So to avoid nodes from different tests colliding on ports, the port assignment must be deterministic (can not be dynamic).
