History
Robert Watson 2082ca5d57 Use the IPX PCB list mutex and IPX PCB mutexes to lock down the SPX 
portion of IPX/SPX:

- Protect IPX PCB lists with the IPX PCB list mutex, in particular
  when calling PCB and PCB list manipulation routines in ipx_pcb.c.
- Protect both IPX PCB state and SPX PCB state using the IPX PCB
  mutex.
- Generally annotate locking, as well as adding liberal use of lock
  assertions to document locking requirements.
- Where possible, use unlocked reads when reading integer or smaller
  sized socket options on SPX sockets.
- De-spl throughout.

Notes:

- spx_input() expects both the list mutex and PCB mutex to be held
  on entry, but will release both on return.  Because sonewconn() is
  called from spx_input(), it may actually drop one PCB lock and
  acquire another during generation of a new connection, meaning the
  caller is not in a position to unlock the PCB mutex.
