Free holding cell on monitor-updating-restored when there's no upd

If there is no pending channel update messages when monitor updating
is restored (though there may be an RAA to send), and we're
connected to our peer and not awaiting a remote RAA, we need to
free anything in our holding cell.

However, we don't want to immediately free the holding cell during
channel_monitor_updated as it presents a somewhat bug-prone case of
reentrancy:
 a) it would re-enter user code around a monitor update while being
    called from user code notifying us of the same monitor being
    updated, making deadlocs very likely (in fact, our fuzzers
    would have a bug here!),
 b) the re-entrancy only occurs in a very rare case, making it
    likely users will not hit it in testing, only deadlocking in
    production.

Thus, we add a holding-cell-free pass over each channel in
get_and_clear_pending_msg_events. This fits up nicely with the
anticipated bug - users almost certainly need to process new
network messages immediately after monitor updating has been
restored to send messages which were not sent originally when the
monitor updating was paused.

Without this, chanmon_fail_consistency was able to find a stuck
condition where we sit on an HTLC failure in our holding cell and
don't ever handle it (at least until we have other actions to take
which empty the holding cell).

Make payments not duplicatively fail/succeed on reload/reconnect

We currently generate duplicative PaymentFailed/PaymentSent events
in two cases:

a) If we receive a update_fulfill_htlc message, followed by a
   disconnect, then a resend of the same update_fulfill_htlc
   message, we will generate a PaymentSent event for each message.

b) When a Channel is closed, any outbound HTLCs which were relayed
   through it are simply dropped when the Channel is. From there,
   the ChannelManager relies on the ChannelMonitor having a copy of
   the relevant fail-/claim-back data and processes the HTLC
   fail/claim when the ChannelMonitor tells it to.

   If, due to an on-chain event, an HTLC is failed/claimed, and
   then we serialize the ChannelManager, but do not re-serialize
   the relevant ChannelMonitor, we may end up getting a duplicative
   event.

In order to provide the expected consistency, we add explicit
tracking of pending outbound payments using their unique
session_priv field which is generated when the payment is sent.
Then, before generating PaymentFailed/PaymentSent events, we check
that the session_priv for the payment is still pending.

Thix fixes #209.

Since InvoiceFeatures are an implementation detail of InvoiceBuilder, an
explicit call is needed to support the basic_mpp feature. Since it is
dependent on the payment_secret feature, conditionally define the

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
non-propagating transactions in casee of failing fee festimation.
