ProcessMessages will now return earlier when processing headers
messages, rather than continuing on (and do nothing).

Currently we have no rotation of outbound peers. If an outbound peer
stops serving us blocks, or is on a consensus-incompatible chain with
less work than our tip (but otherwise valid headers), then we will never
disconnect that peer, even though that peer is using one of our 8
outbound connection slots. Because we rely on our outbound peers to
find an honest node in order to reach consensus, allowing an
incompatible peer to occupy one of those slots is undesirable,
particularly if it is possible for all such slots to be occupied by such
peers.
Protect against this by always checking to see if a peer's best known
block has less work than our tip, and if so, set a 20 minute timeout --
if the peer is still not known to have caught up to a chain with as much
work as ours after 20 minutes, then send a single getheaders message,
wait 2 more minutes, and if a better header hasn't been received by then,
disconnect that peer.
Note:
- we do not require that our peer sync to the same tip as ours, just an
equal or greater work tip. (Doing otherwise would risk partitioning the
network in the event of a chain split, and is also unnecessary.)
- we pick 4 of our outbound peers and do not subject them to this logic,
to be more conservative. We don't wish to permit temporary network
issues (or an attacker) to excessively disrupt network topology.

When in IBD, we'd like to use all our outbound peers to help us
sync the chain. Disconnect any outbound peers whose headers have
insufficient work.

There are a few too many edge-cases here to make this a scripted diff.
The following commits will move a few functions into PeerLogicValidation, where
the local connman instance can be used. This change prepares for that usage.

A peer could try to waste our resources by sending us unrequested blocks with
low work, eg to fill up our disk. Since
e2652002b6011f793185d473f87f1730c625593b we no longer request blocks until we
know we're on a chain with more than nMinimumChainWork (our anti-DoS
threshold), but we would still process unrequested blocks that had more work
than our tip. This commit fixes that behavior.

Nodes don't consider themselves out of "initial block download" until
their active chain has more work than nMinimumChainWork.
While in initial block download, nodes won't relay blocks to their
peers, so test that this parameter functions as intended by verifying
that block relay only succeeds past a given node once its
nMinimumChainWork has been exceeded.

This should fix issues with the multiwallet test and symlinks
when the tmpdir is a relative path.
Rather than fixing os.symlink to work with paths relative to a
directory descriptor, which does not work on Windows, normalize
the path instead.

Make sure wallet databases have unique fileids. If they don't, throw an error.
BDB caches do not work properly when more than one open database has the same
fileid, because values written to one database may show up in reads to other
databases.
Bitcoin will never create different databases with the same fileid, but users
can create them by manually copying database files.
BDB caching bug was reported by Chris Moore <dooglus@gmail.com>

The most recent update replaced the minimal image with a large one for the
'generic' image. Switching back to 'minimal' should reduce dependencies and
maybe speed us up some.
It should also eliminiate the need for aa2e0f09e.

Pull request description:
This includes test related backports for 0.15.1. The motivation is twofold:
* Make backporting new tests written for current master easier
* Fix the most common test issues that happen(ed) frequently on travis
Even though this includes the new TestNode class, which comes with a lot
of refactoring, I believe that the issues caused by refactoring are found
and fixed by now.
