    runtime: minor simplifications to signal code · eb268cb3
    Ian Lance Taylor authored
    Change setsig, setsigstack, getsig, raise, raiseproc to take uint32 for
    signal number parameter, as that is the type mostly used for signal
    numbers.  Same for dieFromSignal, sigInstallGoHandler, raisebadsignal.
    
    Remove setsig restart parameter, as it is always either true or
    irrelevant.
    
    Don't check the handler in setsigstack, as the only caller does that
    anyhow.
    
    Don't bother to convert the handler from sigtramp to sighandler in
    getsig, as it will never be called when the handler is sigtramp or
    sighandler.
    
    Don't check the return value from rt_sigaction in the GNU/Linux version
    of setsigstack; no other setsigstack checks it, and it never fails.
