This will be used by onchaind for now, but also for openingd and channeld
in future, so it returns the old revocation secret as well.
Of course, the HSM should refuse to sign a commitment transaction if it
has handed out the revocation secret previously!

We had a number of entry points into the HSM, all with different
behavior, so this is my attempt at unifying the way we handle
clients. Every client, except master, now takes the same path entry
point to the HSM and we use capability bit flags to indicate whether
the client is allowed to execute a set of operations.
