From: Sebastian Glita <gseba at cs.upt.ro>

A simple fixup in "dixutils.c:_CallCallbacks":
- by moving recursion count check *before* list iteration and actual callbacks'
invocation;
- can say for sure, though, whether counters (member `int inCallback' from
"include/dixstruct.h:171:CallbackListRec" structure) were supposed to grow
greater than 1 before iteration,
- so cannot ascertain whether the new behavior is required.

The mutual recursive functions' chain:

1. dix/dixutils.c:CallCallbacks:877
2. dix/dixutils.c:_CallCallbacks:743
3. record/record.c:RecordFlushAllContexts:867
4. record/record.c:RecordFlushReplyBuffer:251
5. os/io.c:WriteToClient:824
