protocol: split message update_remove_htlc into update_timedout_htlc and update_routefail_htlc, remove update_remove_htlc_delay.
...
For the moment, there's no way to remove an in-progress HTLC before
it's timed out. The other side can remove it with a routefail, but
you can't push for it to be removed.
We may add that later, but by definition it's only a polited request, and
normally we should rely on timeouts.

This gets truncated for on-chain transactions (thus, rounding may

For open transactions, locktime is a delay we require on the other

off if necessary.
For HTLCs, it's an absolute expiry time.
