Modified files:
sys/sys kse.h proc.h
sys/kern kern_switch.c kern_synch.c kern_thread.c
Log:
Adjust code for userland preemptive. Userland can set a quantum in
kse_mailbox to schedule an upcall, this is useful for userland timeout
routine, for example pthread_cond_timedwait().
Also extract upcall scheduling code from kse_reassign and create
a new function called thread_switchout to include these code.
