d9434918d2 qa: add a test to detect leaky p2p messages
This is certainly not exhaustive, but it's better than nothing. Adds checks
for:

- Any message received before sending a version
- Any message received other than version/reject before sending a verack

It also tries to goad the remote into sending a pong, address, or block
announcement.

cbfc5a6728 net: require a verack before responding to anything else
7a8c251901 made this logic hard to follow. After that change, messages would
not be sent to a peer via SendMessages() before the handshake was complete, but
messages could still be sent as a response to an incoming message.

For example, if a peer had not yet sent a verack, we wouldn't notify it about
new blocks, but we would respond to a PING with a PONG.

This change makes the behavior straightforward: until we've received a verack,
never send any message other than version/verack/reject.

The behavior until a VERACK is received has always been undefined, this change
just tightens our policy.

This also makes testing much easier, because we can now connect but not send
version/verack, and anything sent to us is an error.

8502e7acbe net: parse reject earlier
Prior to this change, all messages were ignored until a VERSION message was
received, as well as possibly incurring a ban score.

Since REJECT messages can be sent at any time (including as a response to a bad
VERSION message), make sure to always parse them.

Moving this parsing up keeps it from being caught in the
if (pfrom->nVersion == 0) check below.

c45b9fb54c net: correctly ban before the handshake is complete
7a8c251901 made a change to avoid getting into SendMessages() until the
version handshake (VERSION + VERACK) is complete. That was done to avoid
leaking out messages to nodes who could connect, but never bothered sending
us their version/verack.

Unfortunately, the ban tally and possible disconnect are done as part of
SendMessages(). So after 7a8c251901, if a peer managed to do something
bannable before completing the handshake (say send 100 non-version messages
before their version), they wouldn't actually end up getting
disconnected/banned. That's fixed here by checking the banscore as part of
ProcessMessages() in addition to SendMessages().

3cf991756c Add test to check new importmulti "now" value
Easiest way to test this was to expose the timestamp via the validateaddress
RPC (which was already looking up and returning key metadata).

442887f27f Require timestamps for importmulti keys
Additionally, accept a "now" timestamp, to allow avoiding rescans for keys
which are known never to have been used.

Note that the behavior when "now" is specified is slightly different than the
previous behavior when no timestamp was specified at all. Previously, when no
timestamp was specified, it would avoid rescanning during the importmulti call,
but set the key's nCreateTime value to 1, which would not prevent future block
reads in later ScanForWalletTransactions calls. With this change, passing a
"now" timestamp will set the key's nCreateTime to the current block time
instead of 1.

Fixes #9491

321d0fc6b6 net: fix a few races. Credit @TheBlueMatt
These are (afaik) all long-standing races or concurrent accesses. Going
forward, we can clean these up so that they're not all individual atomic
accesses.

- Reintroduce cs_vRecv to guard receive-specific vars
- Lock vRecv/vSend for CNodeStats
- Make some vars atomic.
- Only set the connection time in CNode's constructor so that it doesn't change

5e903a5ed9 devtools: Handle Qt formatting characters edge-case in update-translations.py
If both numeric format specifiers and "others" are used, assume we're
dealing with a Qt-formatted message. In the case of Qt formatting (see
https://doc.qt.io/qt-5/qstring.html#arg) only numeric formats are
replaced at all. This means "(percentage: %1%)" is valid (which was
introduced in #9461), without needing any kind of escaping that would be
necessary for strprintf.  Without this, this function would wrongly
detect '%)' as a printf format specifier.

Make sure that RPC tests are actually checking failures correctly by:

- Catching JSON RPC exceptions and verifying the error codes and messages.
- Failing the test case if the JSON RPC exception isn't raised.
