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

like Alpine may have stricter requirements.

split the channel and commit_tx routines into initial_channel and
initial_commit_tx (no HTLC support) and move full HTLC supporting versions
into channeld.

Otherwise valgrind tells you when you test a hash; you want to
know if you hash uninitialized memory long before that.
