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.

protocol: increase HTLC precision to 1/1000 satoshi.
This gets truncated for on-chain transactions (thus, rounding may
contribute to fees).
This also means we currently have an upper bound of 0.04 BTC per HTLC;
this can be increased later if required.

protocol: rename locktime fields to "delay" and "expiry"

For HTLCs, it's an absolute expiry time.
