Robert Watson f6c0cce6d9 Introduce a mutex into struct sockbuf, sb_mtx, which will be used to 
protect fields in the socket buffer.  Add accessor macros to use the
mutex (SOCKBUF_*()).  Initialize the mutex in soalloc(), and destroy
it in sodealloc().  Add addition, add SOCK_*() access macros which
will protect most remaining fields in the socket; for the time being,
use the receive socket buffer mutex to implement socket level locking
to reduce memory overhead.
