Do not wait until wsReader routine gracefully finishes its work before
WS connection close. Instead, firstly close the connection, and after
that wait for proper wsReader exit.
It's a harsh way, but I don't have any other options to try, because
wsReader routine hangs on `ws.ReadMessage()` operation for more than
ReadDeadline (more than 5 seconds) during test cleanup which results in
the test timeout.

Close#2956. The failure reason is similar to the one described in #3396
for TestNotary: Blockchain's notificationDispatcher is listening to
block events from storeBlock via separate channel. By the moment single
block addition is finished, notification may or may not be properly
handled by notificationDispatcher, especially given the fact that our
runners are slow. As a result, assert.Eventually with 1-second awaiting
period may fail. This issue is solved by adding one more block, because
the second AddBlock finishes only when it sends block addition event to
notificationDispatcher loop, which means that the previous event was
handled.

Made connections in parallel to check the limit and attempt to make one
more connection beyond the limit. Only "default" test case is failing,
because default number of connections is 64 (quite large for slow
runners). The failure reason is:
* given ~1 second for [dealing + request] per connection (time is taken
from the test log)
* by the moment 65-th connection is reached, some connections from the
start of the test have died due to inactivity (this process literally
takes 1 minute)

1. Replace isFinished atomic variable with a channel, no functional changes
here, just use more common way as all our services do.
2. Do not check erors from SetReadDeadline and ReadMessage on exit. It
seems to be not quite right because connection is not closed by this
moment, and thus, these error checks are racy.
3. Add read timeout for the message reader. It is needed because some
tests may leave message unread in the end which results in hanging
test cleanup.
4. Add drain loop to message reader in order not to block WS reader on
sending message.

It's clear that TestBadSubUnsub is hanging on test cleanup, in
particular, on attempt to wait for wsRead routine to exit. The only
place where wsRead routine may hang is sending to msgCh in case if
receiver is not going to read from this channel:

Default http.Client and http.Transport can be really slow. Also on
windows Timeout: time.Second was not enough. Probably network related
issue. As mentioned in https://github
.com/nspcc-dev/neo-go/issues/2975#issuecomment-1750523651 forcely use
only tcp4 and FallbackDelay: -1. This made TestRPC little bit faster so
gh windows runner can manage it without timeout or POST request fails.

This is not the way intended in https://github.com/neo-project/proposals/pull/156.
-511 covers _both_ cases because users hardly can distinguish one from another,
it's just that our mempool implementation has error codes for both..
Signed-off-by: Roman Khimov <roman@nspcc.ru>
mempool.ErrInsufficientFunds is used when sender doesn't have enough
balance to pay the submitted transaction fees (-511 code according to
https://github.com/neo-project/proposals/pull/156). mempool.ErrConflict is
used when sender is not able to pay the overall transactions fee sum in
the pool (generic -500 error according to the proposal).
This bugfix is kind of breaking change for those users who relied on the
old -511 code previously returning "insufficient funds" error.

Added sync logs for every service separately to provide the ability to
