This stuff should go in a C file, not in a header. Also you should use
ERR instead of fprintf, and error messages should be in English <g>

This is not used, it would be better to wait until you actually need
per-thread data to add it.

Do you really need locking around Carbon calls, or is this just
imitating x11drv?  (either way there's no reason to export those).

GetProp is not the best choice for associating data to a window as it
requires a server round trip. A process-local mechanism is preferable.
