Maintain the sequence number as a uint64_t.

We spend a lot of effort implementing a big-endian sequence number
update, etc., when the sequence number is just a 64-bit counter. (Or
48-bit counter in DTLS because we currently retain the epoch
separately. We can probably tidy that a bit too, but I'll leave that
for later. Right now the DTLS record layer state is a bit entwined
with the TLS one.)

Just store it as uint64_t. This should also simplify
