kernel - Fix numerous MP issues with sockbuf's and ssb_flags part 1/2
* Use atomic ops for ssb_flags handling
* Use atomic_cmpset_int() to interlock SSB_LOCK with SSB_WANT, and
SSB_WAIT with SSB_WAKEUP.
Note in particular that WAIT/WAKEUP assumes the client side of the
socket is single threaded via an appropriate lock. This needs more
work.
