Log Message:
Don't bother keeping sa_nstackentries stored; it's a constant.

Add a sa_woken field, for optimizing the switch between sa_yield and a
recently-woken LWP.

Add sa_rstacks and sa_nrstacks for "reserving" upcall stacks for
UNBLOCKED upcalls at sa_switch() time, so that such upcalls are always
generated in pairs.

Define SA_FLAG_ALL for internal use.

Adjust to sa_upcall0() prototype change.

Add prototype for sa_yield() and sa_yieldcall().
