Have c-lightning nodes send out the largest value for
`htlc_maximum_msat` that makes sense, ie the lesser of
the peer's max_inflight_htlc value or the total channel
capacity minus the total channel reserve.
LND does this, and we get upset with it. I had assumed we would only
do this after funding_locked (since we don't consider the channel
shortid stable until that point), but TBH 6 confirms is probably
enough.

Under stress, it fails (test_restart_many_payments, the next test).
I suspect a deep misunderstanding in the comparison code, will chase
separately.

We do this a lot, and had boutique helpers in various places. So add
a more generic one; for convenience it returns a pointer to the new
end element.
I prefer the name tal_arr_expand to tal_arr_append, since it's up to
the caller to populate the new array entry.

That matches the other CSV names (HSM was the first, so it was written
before the pattern emerged).

@renepickhardt: why is it actually lightningd.c with a d but hsm.c without d ?
And delete unused gossipd/gossip.h.
