Reorder the mbuf defines to make more sense and group related flags

together.

Add M_FLAG_PRINTF for use with printf(9) %b indentifier.

Use the generic mbuf flags print names in the net80211 code and adjust
the protocol specific bits for their new positions.

Change SCTP M_PROTO mapping from 5 to 1 to fit within the 16bit field
they use internally to store some additional information.
