SomberNight	acb0d7ebac	lnchannel: better checks for "update_add_htlc" ... I believe this now implements all the checks listed in BOLT-02 for update_add_htlc, however, the BOLT is sometimes ambiguous, and actually the checks listed there IMO are insufficient.

SomberNight	777e350fae	lnchannel: partly fix available_to_spend ... we were looking at inconsistent ctns and we were looking at the wrong subject's ctx all the FIXMEs and TODOs here will still warrant some attention.
