It fits in a u32, but we mix it with other values which could cause
overflow, so let's just use u64 everywhere.

This is generally redundant, since HTLC pointer is in that side's
commit_info, but makes HTLC completely self-contained.

No more copies!
I tried changing the cstate->side[].htlcs to htlc_map rather than a
simple pointer array, but we rely on those array indices heavily for
permutation mapping, and it turned into a major rewrite (especially
for the steal case).
Eventually, we're going to want to reconstruct the commit info for
older commit txs rather than keeping all the permutation and
per-commit-info HTLC information in memory, so we can do the work
then.

It's a more logical name, and a more logical place. We change
"funding" to "channel" in the remaining exposed symbols, too.
