Attached is a privates.c where dixLookupPrivate has been reduced to a
test + array index.
The problem is that it needs to store the array index into the memory
referenced by the "key" pointer. Currently there is no requirement on
"key" other than being a unique value.
So committing this requires some refactoring first. Basically turning
"static DevPrivateKey foo = &foo" into "static int blah; static
DevPrivateKey foo = &blah". After it's done it can be committed. Maybe
