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.

The `splashFinished` event was never sent if AppInitMain fails,
causing the splash screen to stick around, causing problems
later.
This bug has existed for a while but is now trigging potential crashed
because the splash screen subscribes to wallet events.

If the ShutdownRequested() check at the top of ActivateBestChain()
returns false during initial genesis block load we will fail an
assertion in UTXO DB flush as the best block hash IsNull(). To work
around this, we move the check until after one round of
ActivateBestChainStep(), ensuring the genesis block gets connected.

If the user somehow manages to get into ShutdownRequested before
ThreadImport gets to ActivateBestChain() we may hang waiting on
condvar_GenesisWait forever. A simple wait_for and
