  Modified files:
    sys/sys              proc.h 
  Log:
  - In the locking key for struct proc, generalize the '+' symbol to mean
    that write access to a member requires both locks and read access only
    requires one of the given locks.  Convert instances of '(c+)' to
    '(c + k)' as a result.
  - Change p_pptr from (e) to (c + e).
  - Change p_oppid from (c) to (c + e).
  - Change p_args from (b?) to (c + k).
  - Move the actual work of STOPEVENT, PHOLD, and PRELE to _STOPEVENT,
    _PHOLD, and _PRELE.  The new macros do not acquire the proc lock and
    simply assert that it is held.  The non _ prefixed macros acquire the
    proc lock and then call the _ prefixed macros.
  - Add a PROC_LOCK_NOSWITCH() macro to be used when releasing the proc lock
    while already holding a spin lock (usually sched_lock).
  - Add a PROC_LOCK_ASSERT() macro to be used to make assertions about the
    proc lock.  It takes the usual mtx_assert() macro arguments as its
    second argument.
