* libc/include/sys/signal.h: Add more complete set of POSIX
signal functionality including real-time and threaded signals.

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.
* libc/stdlib/mprec.c (ulp, b2d, d2b): changed a few expressions
like x << y-z to the equivalent x << (y-z).

initializers for __infinity (need three: for __infinity[1] array,
