integer overflow in _XQueryFont() on 32-bit platforms [CVE-2013-1981 1/13]
If the CARD32 reply.nCharInfos * sizeof(XCharStruct) overflows an
unsigned long, then too small of a buffer will be allocated for the
data copied in from the reply.
v2: Fix reply_left calculations, check calculated sizes fit in reply_left
