store errno on the private process stack so its always per process and not just per memory space. errno itself becomes a macro dereferencing int *_errnoloc; which is initialized from main9.s pointing to the private stack location. various fixes in programs that just imported errno variable with "extern int errno;" instead of including <errno.h>.
