include/signal.h: There was massive namespace pollution from including <sys/types.h>. POSIX functions were declared even when _ANSI_SOURCE is defined. sys.sys/signal.h: NSIG was declared even if _ANSI_SOURCE or _POSIX_SOURCE is defined. sig_atomic_t wasn't declared if _POSIX_SOURCE is defined. Declare a typedef for signal handling functions and use it to unobfuscate declarations and to avoid half-baked function types that cause unwanted compiler warnings at certain warning levels. Fix confusing comment about SA_RESTART. sys/i386/include/signal.h: This has to be included to get the declaration of sig_atomic_t even when _ANSI_SOURCE is defined, so be more careful about polluting the ANSI namespace. Uniformize idempotency ifdefs.
