 Modified Files:
         src/sys/kern: sys_lwp.c
 
 Log Message:
 - Remove the LWP counters. The race between park/unpark rarely occurs
   so it's not worth counting.
 
 - lwp_wakeup: set LW_UNPARKED on the target. Ensures that _lwp_park will
   always be awoken even if another system call eats the wakeup, e.g. as a
   result of an intervening signal. To deal with this correctly for other
   system calls will require a different approach.
 
 - _lwp_unpark, _lwp_unpark_all: use setrunnable if the LWP is not parked
   on the same sync queue: (1) simplifies the code a bit as there no point
   doing anything special for this case (2) makes it possible for p_smutex
   to be replaced by p_mutex and (3) restores the guarantee that the 'hint'
   argument really is just a hint.
