add setting gs/fsbase
* i386/i386/i386asm.sym: add offsets for asm
* i386/i386/pcb.c: switch FSBASE/GSBASE on context switch and
implement accessors in thread setstatus/getstatus
* i386/i386/thread.h: add new state to thread saved state
* kern/thread.c: add i386_FSGS_BASE_STATE handler
* x86_64/locore.S: fix fs/gs handling, skipping the base address and
avoid resetting it by manually re-loading fs/gs
