        * libc/machine/i386/i386mach.h: added SOTYPE_FUNCTION to set type
        of global entry points if _I386MACH_NEED_SOTYPE_FUNCTION is defined;
        Added __CLI and __STI macros (controlled via
        _I386MACH_ALLOW_HW_INTERRUPTS macro).

        (that's libc/machine/i386/*.S) added SOTYPE_FUNCTION(symbol)
        for all global entry points.
        * libc/machine/i386/setjmp.S: removed code replicated in
        libc/machine/i386/i386mach.h and included i386mach.h instead;
        Use __CLI and __STI instead of cli and sti.
