    Revert "Don't call XInitThreads in Wayland"
    
    This reverts commit a9ede294c57bc5738be3c33cba4ef88b9a7d4a0e.
    
    It causes empathy-call to crash when run in X11, and fixes absolutely
    nothing. See the bug for details.
    
    Thanks to Diane Trout for investigating and preparing a substantially-
    identical patch.
