And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).
config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

For quiescence, we can't have sent any updates at all.
But for upgrades on reconnection, we may have already added
uncommitted HTLCs for retransmission, but they don't count towards
"are we quiesced" since they're not sent yet.

There are several reports of desynchronization with LND here; a simple
approach is to only have one feerate change in flight at any time.
Even if this turns out to be our fault, it's been a historic area of
confusion, so this restriction seems reasonable.
Changelog-Fixed: Protocol: Don't create more than one feerate change at a time, as this seems to desync with LND.
Fixes: #4152

Previously we've used the term 'funder' to refer to the peer
paying the fees for a transaction; v2 of openchannel will make
this no longer true. Instead we rename this to 'opener', or the
peer sending the 'open_channel' message, since this will be universally
true in a dual-funding world.
This uses the same state machine as HTLCs, but they're only
ever added, not removed. Since we can only have one in each
state, we use a simple array; mostly NULL.
We could make this more space-efficient by folding everything into the
first 5 states, but that would be more complex than just using the
identical state machine.
One subtlety: we don't send uncommitted fee_states over the wire.
