8df29d169c The overflow check mul_overflows_s64(int64_t, int64_t) overflows and triggers UB :-) Remove it 
The overflow check `mul_overflows_s64(int64_t, int64_t)` overflows.
Since this is an signed integer overflow this triggers UB, which
in turn means that we cannot trust the check.

Luckily mul_overflows_s64(int64_t, int64_t) is unused. Removing it.

8c22bd9ee1 headers: fix up header idempotent lines. 
For future reference, done via:
	for f in `find wire/ bitcoin/ common/ lightningd -name '*.h' ! -name 'gen*'`; do ID=`echo -n LIGHTNING/$f | tr 'a-z' 'A-Z' | tr -cs 'A-Z0-9' _`; sed 's/^#\(ifndef\|define\) .*_H$/#\1 '$ID/ < $f | sed 's,#endif /..*_H ./$,#endif /* '$ID' */,' | bagto $f; done

85ff95e829 common: new directory for any shared objects. 
To avoid everything pulling in HTLCs stuff to the opening daemon, we
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.
