* 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).
* libc/machine/i386/f_atan2.S libc/machine/i386/f_atan2f.S

libc/machine/i386/memset.S libc/machine/i386/setjmp.S
libc/machine/i386/strchr.S libc/machine/i386/strlen.S:
(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.
