History
Christian S.J. Peron 604afec496 Somewhat re-factor the read/write locking mechanism associated with the packet 
filtering mechanisms to use the new rwlock(9) locking API:

- Drop the variables stored in the phil_head structure which were specific to
  conditions and the home rolled read/write locking mechanism.
- Drop some includes which were used for condition variables
- Drop the inline functions, and convert them to macros. Also, move these
  macros into pfil.h
- Move pfil list locking macros intp phil.h as well
- Rename ph_busy_count to ph_nhooks. This variable will represent the number
  of IN/OUT hooks registered with the pfil head structure
- Define PFIL_HOOKED macro which evaluates to true if there are any
  hooks to be ran by pfil_run_hooks
- In the IP/IP6 stacks, change the ph_busy_count comparison to use the new
  PFIL_HOOKED macro.
- Drop optimization in pfil_run_hooks which checks to see if there are any
  hooks to be ran, and returns if not. This check is already performed by the
  IP stacks when they call:

        if (!PFIL_HOOKED(ph))
                goto skip_hooks;

- Drop in assertion which makes sure that the number of hooks never drops
  below 0 for good measure. This in theory should never happen, and if it
  does than there are problems somewhere
- Drop special logic around PFIL_WAITOK because rw_wlock(9) does not sleep
- Drop variables which support home rolled read/write locking mechanism from
  the IPFW firewall chain structure.
- Swap out the read/write firewall chain lock internal to use the rwlock(9)
  API instead of our home rolled version
- Convert the inlined functions to macros
