Now we correctly use the remote revocation basepoint, we need to set
it in run-channel (instead of the local revocation basepoint).
We also update all the comments, as per (pending) spec commit:

This was included in the lightningnetwork/lightning-rfc#105 update
to the test vectors, and it's a good idea. Takes a bit of work to
calculate (particularly, being aware of rounding issues).

aka "BOLT 3: Use revocation key hash rather than revocation key",
which builds on top of lightningnetwork/lightning-rfc#105 "BOLT 2,3,5:
Make htlc outputs of the commitment tx spendable with revocation key".
This affects callers, since they now need to hand us the revocation
pubkey, but commit_tx has that already anyway.

Only minor changes, but I add some more spec text to
lightningd/test/run-commit_tx.c to be sure to catch if it changes
again.
One reference isn't upstream yet, so had to be commented out.

It's currently written to produce "local" commit-txs, but of course we
need to produce remote ones too, for signing.
Thus instead of using "remote" and "local" we use "other" and "self",
and indicate with a single "side" flag which we're generating (because
that changes how HTLCs are interpreted).
This also adds to the tests: generate the remote view of the commit_tx
and make sure it matches!

We were using the remote per_commitment_point instead of the local
per_commitment_point to generate the remotekey for the local transaction.
