integer overflow in XRRQueryOutputProperty() [CVE-2013-1986 1/4]

rep.length is a CARD32, while rbytes was a signed int, so
   rbytes = sizeof (XRRPropertyInfo) + rep.length * sizeof (long);
could result in integer overflow, leading to an undersized malloc
and reading data off the connection and writing it past the end of
the allocated buffer.
