    <signal.h>: Sanitize the feature tests.
    
    * Generally, in our headers, we don't check the (user-settable)
      _POSIX_SOURCE and _ANSI_SOURCE, but instead __XSI_VISIBLE,
      __POSIX_VISIBLE and __BSD_VISIBLE, which are set by <sys/cdefs.h>
      based on what the user chose. Do the same in the CPU specific
      signal headers.
    
    * psignal() is now a standard function (per 200809).
    
    * Add missing __restrict qualifiers.
