Modified Files:
	basesrc/lib/libpthread/arch/i386 [nathanw_sa]: pthread_switch.S

Log Message:
Substantial rework:
 - Make pthread__switch() just a plain switch, and move the
   switch-to-next code to pthread__switch_away. Saves a stack switch,
   test, and branch in the pthread_switch case, a _getcontext_u() and
   associated stack frobbing in the switch_away case, and several
   points of sanity.
 - Remove a poorly-thought-out ucontext-dodge in STACK_SWITCH.
 - Fill in PT_SWITCHTO and PT_SWITCHTOUC in the new_preempt path as
   well as the old_preempt path in pthread__locked_switch() and
   pthread__upcall_switch().
