    * configure.in: Added check for socket library and SendMsg
    check.
    * acconfig.h: Added this file with a HAVE_SENDMSG definition.
    * gnome-pty-helper/configure.in: Added checks needed for the
    source code, including the SendMsg check.
    * src/pty.c: Corrected _vte_pty_pipe_open so it works on
    Solaris.
    *src/vte.c: Made some speed improvements so vte_invalidate_cells
    is not called for every character in the while loop in
    vte_process_incoming, but only once when the while loop is done.
