Inherit fpu control word from parent to child
* i386/i386/thread.h (struct pcb): Add init_control field.
* i386/i386/fpu.h (fpinherit): New prototype.
* i386/i386/fpu.c (fpinit): Add thread parameter. When init_control field is
set, use that value instead of a hardcoded one.
(fpinherit): New function.
(fp_load): Pass thread parameter to fpinit().
* kern/thread.c (thread_create): Pass parent task to pcb_init().
* i386/i386/pcb.c (pcb_init): Add parent_task parameter, call fpinherit when
it is equal to current_task().
