    [cairo-xlib] Fix max-request size calculations

    First, XMaxRequestSize returns number of 4-byte words.  So multiply by 4 is
    needed in all uses.  Next, XRenderAddGlyphs uses BIG-REQUEST extension if
    available, so when checking for glyph size overflow, we should use
    XExtendedMaxRequestSize() first.

    Also use the right format when calculating glyph size.

    See bug #4339 for history.
