    Remove SIGIO support for input [v5] · 6a5a4e60
    Keith Packard authored
    This removes all of the SIGIO handling support used for input
    throughout the X server, preparing the way for using threads for input
    handling instead.
    
    Places calling OsBlockSIGIO and OsReleaseSIGIO are marked with calls
    to stub functions input_lock/input_unlock so that we don't lose this
    information.
    
    xfree86 SIGIO support is reworked to use internal versions of
    OsBlockSIGIO and OsReleaseSIGIO.
    
    v2: Don't change locking order (Peter Hutterer)
    v3: Comment weird && FALSE in xf86Helper.c
        Leave errno save/restore in xf86ReadInput
        Squash with stub adding patch (Peter Hutterer)
    v4: Leave UseSIGIO config parameter so that
        existing config files don't break (Peter Hutterer)
    v5: Split a couple of independent patch bits out
        of kinput.c (Peter Hutterer)
