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.

Pull request description:
Similar to #12967 this contains all relevant bugfixes and improvements to the functional test suite.
I didn't include fixes to make the tests run on Windows, since that is still an ongoing effort and doesn't seem worth to backport.
As all of these are clean cherry-picks, I suggest reviewers redo the cherry-picks to get the same branch and then run the extended test suite.

If a cookie file exists in a datadir prior to node startup, it must have
been leftover from a prior unclean shutdown. As bitcoind will overwrite
it anyway, delete it before starting up to prevent the test framework
from inadvertently trying to connect using stale credentials.

rpc_net.py would intermittently fail on Travis, probably
due to assuming that two consecutive RPC calls were atomic.
Fix this by only testing that amounts are bounded above and
below rather than equal.

The output would produce arbitrary number of decimal points, sometimes resulting in 9 decimals:
AssertionError: Fee of 0.00000415 BTC too low! (Should be 0.000006175 BTC)
The above looks like the expected fee is 6175 sats when in reality it's 618.

25afebc2ba depends: Switch expat download to GitHub (fanquake)
Pull request description:
@droark [mentioned](https://github.com/bitcoin/bitcoin/pull/12402#issuecomment-370098383) the expat download was failing when trying to gitian build 0.16.
I tried locally and also saw issues:
```
make download

This switches to downloading from GitHub, as we are doing in master.

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.
