composite: add panoramix support

Taken from:

With minor style fixes, ported to dixLookupResourceByType, and ported
away from client->noClientException and xalloc/xfree.

v2: Fix a memory leak in PanoramiXCompositeNameWindowPixmap, spotted by
James Jones.
v3: Fix a buglet in PanoramiXCompositeUnredirectSubwindows, spotted by
Dave Airlie.
v4: Fix a style issue with resource lookup noted by Jamey Sharp.
