Add kernel support needed for the KSE-aware libpthread:
	- Use ucontext_t's to store KSE thread state.
	- Synthesize state for the UTS upon each upcall, rather than
	  saving and copying a trapframe.
	- Save and restore FPU state properly in ucontext_t's.
	- Deliver signals to KSE-aware processes via upcall.
	- Rename kse mailbox structure fields to be more BSD-like.
	- Store the UTS's stack in struct proc in a stack_t.
