Implement _ia64_enter_uts(). The purpose of this function is to switch

the register stack and memory stack and call the function given to it.

While here, provide empty, non-working, stubs for the context functions
(_ia64_save_context() and _ia64_restore_context()) so that anyone can at
least compile libkse from CVS sources. Real implementations will follow
soon.
