It seems xcb/x11 have some bugs related to sizeof(long), in concrete using 32 bit variables for dpy->request et al in AMD64.
This patch fixes some crashes for me.

I've used uint64_t instead unsigned long as it seems preferred through the
codebase.
Note that both req->sequence and dpy->request are defined as unsigned long.
