this test checks invariants in ordering of
BlockConnected / BlockDisconnected / UpdatedChainTip signals

If multiple threads are invoking ActivateBestChain, it was possible to have
them working towards different tips, and we could arrive at a less work tip
than we should. Fix this by introducing a ChainState lock which must
be held for the entire duration of ActivateBestChain to enforce
exclusion in ABC.

Technically, some internal datastructures may be in an inconsistent
state if we do this, though there are no known bugs there. Still,
for future safety, its much better to only unlock cs_main if we've
made progress (not just tried a reorg which may make progress).

* Litecon: Modify thread names
Since this string is displayed externally within lists of processes and should be consistent with branding, and not cause confusion for admins, when running "top", "ps aux", "pgrep" or similar commands.
* Litecoin: Remove invalid doxygen link
* Litecoin: Add additional optional build steps for osx builds
Fixes: https://github.com/litecoin-project/litecoin/issues/463
* Litecoin: Show scrypt sse2 status in configure and fix scrypt syntax issue
Instead of crash with an assertion error, simply exit the function
`SyncMetaData` if there is no metadata to sync.
Fixes#13110.

While this isn't a supported build configuration, some build
systems need to build without going through our autotools steps,
so defaulting to something sane may make it easier to build.
Specifically, this fixes the inability to build
rust-bitcoinconsensus on some non-x86 platforms. It needs to build
without our autotools/configure steps to ensure correct compile
args are passed from the rust build system to gcc. Converting the
args from the rust build system to gcc would be a lot of
unmaintainable work.

The blockmaxsize option was marked as deprecated in V0.15.1, and code
was added to convert provided blockmaxsize into blockmaxweight. However,
this code was incorrectly implemented, and blockmaxsize was silently
ignored.
No users have complained about blockmaxsize being ignored, so just
remove it in V0.17.

A risk exists where a malicious DNS seeder eclipses a node by returning an enormous number of IP addresses. In this commit we mitigate this risk by limiting the number of IP addresses addrman learns to 256 per DNS seeder.

0) Adjust BIP30 enforcement values
1) Reduce amount that peers can adjust our time to eliminate an attack vector. Thanks to
coblee for this fix.
2) Zeitgeist2 patch - thanks to Lolcust and ArtForz. This fixes an issue where a
51% attack can change difficulty at will. Go back the full period unless it's the
first retarget after genesis.
3) Avoid overflow in CalculateNextWorkRequired(). Thanks to pooler for the overflow fix.
4) Zeitgeist2 bool fshift bnNew.bits(). Thanks to romanornr for this path.
5) SegWit ContextualCheckBlockHeader adjustment and extra coverage.
6) Reject peer proto version below 70002. Thanks to wtogami for this patch.
7) Send final alert message to nodes warning about removal of the alert system. Thanks to coblee for this patch.
8) Adjust default settings for Litecoin.
This faulty translation contained Chinese messages, and as en_US is our
source language, having a separate translation for it is pointless, remove it.

This commit fixes problems with calling LockDirectory multiple times on
the same directory, or from multiple threads. It also fixes the build on
OpenBSD.
- Wrap the boost::interprocess::file_lock in a std::unique_ptr inside
the map that keeps track of per-directory locks. This fixes a build
issue with the clang 4.0.0+boost-1.58.0p8 version combo on OpenBSD
6.2, and should have no observable effect otherwise.
- Protect the locks map using a mutex.
- Make sure that only locks that are successfully acquired are inserted
in the map.
- Open the lock file for appending only if we know we don't have the
lock yet - The `FILE* file = fsbridge::fopen(pathLockFile, "a");`
wipes the 'we own this lock' administration, likely because it opens
a new fd for the locked file then closes it.

New global variables were introduced in #11403 and not setting them causes:
test_bitcoin: wallet/wallet.cpp:4259: CTxDestination GetDestinationForKey(const CPubKey&, OutputType): Assertion `false' failed.
unknown location(0): fatal error in "importwallet_rescan": signal: SIGABRT (application abort requested)
It's possible to reproduce the failure reliably by running:
src/test/test_bitcoin --log_level=test_suite --run_test=wallet_tests/importwallet_rescan
Failures happen nondeterministically because boost test framework doesn't run
tests in a specified order, and tests that run previously can set the global
variables and mask the bug.

This resolves an issue where getrawmempool() can race mempool
notification signals. Intuitively we use mempool.cs as a "read
lock" on the mempool with cs_main being the write lock, so holding
the read lock intermittently while doing write operations is
somewhat strange.
This also avoids the introduction of cs_main in getrawmempool()
which reviewers objected to in the previous fix in #12273

This prevents a potential race condition if control flow ends up in
`ShutdownHTTPServer` before the thread gets to `queue->Run()`,
deleting the work queue while workers are still going to use it.
