Replace config max counterpary `dust_limit_satoshis` by a constant.

Current Bitcoin Core's policy will reject a p2wsh as a dust if it's
under 330 satoshis. A typical p2wsh output is 43 bytes big to which
Core's `GetDustThreshold()` sums up a minimal spend of 67 bytes (even
if a p2wsh witnessScript might be smaller). `dustRelayFee` is set
to 3000 sat/kb, thus 110 * 3000 / 1000 = 330. As all time-sensitive
outputs are p2wsh, a value of 330 sat is the lower bound desired
to ensure good propagation of transactions. We give a bit margin to
our counterparty and pick up 660 satoshis as an accepted
`dust_limit_satoshis` upper bound.

As this reasoning is tricky and error-prone we hardcode it instead of
letting the user picking up a non-sense value.

Further, this lower bound of 330 sats is also hardcoded as another constant
(MIN_DUST_LIMIT_SATOSHIS) instead of being dynamically computed on
feerate (derive_holder_dust_limit_satoshis`). Reducing risks of

Fix (and test) panic when our counterparty uses a bogus funding tx

During the block API refactor, we started calling
Channel::force_shutdown when a channel is closed due to a bogus
funding tx. However, we still set the channel's state to Shutdown
prior to doing so, leading to an assertion in force_shutdown (that
the channel is not already closed).

This removes the state-set call and adds a (long-overdue) test for
this case.

[peer_handler] Take the peers lock before getting messages to send

Previously, if a user simultaneously called
`PeerHandler::process_events()` from two threads, we'd race, which
ended up sending messages out-of-order in the real world.
Specifically, we first called `get_and_clear_pending_msg_events`,
then take the `peers` lock and push the messages we got into the
sending queue. Two threads may both get some set of messages to
send, but then race each other into the `peers` lock and send the
messages in random order.

Because we already hold the `peers` lock when calling most message
handler functions, we can simply take the lock before calling
`get_and_clear_pending_msg_events`, solving the race.
