dix: Allow zero-height PutImage requests (fix for X.Org's CVE-2015-3418).pr/dix-cve-fixes
The length checking code validates PutImage height and byte width by
making sure that byte-width >= INT32_MAX / height. If height is zero,
this generates a divide by zero exception. Allow zero height requests
explicitly, bypassing the INT32_MAX check.
Fix for regression introduced by fix for CVE-2014-8092.
v2: backports to nx-libs 3.6.x (Mike Gabriel)
v3: port to NXdispatch.c rather than dispatch.c (Mike DePaulo)
