Get rid of the RSMBLY macros.
Turn them into static functions that take in an hm_fragment. It's not
immediately obvious that the frag_off/frag_len bounds checks and the msg_len
consistency check are critical to avoiding an out-of-bounds write. Better to
have dtls1_hm_fragment_mark also check internally.
Also rework the bitmask logic to be clearer and avoid a table.
