Hack adding C11 atomics for setting pool->top
The attached patch uses C11 atomics for setting and reading pool->top. Could
someone check if this patch makes TSan happy?
If so, that someone should also pick up this work and add C11 atomic support
for cairo-atomic-private.h (and configure). Afterwards, _cairo_atomic_int_set()
could be added to this and the freed pool can be fixed up to work properly.
I'm not interested in doing this work myself.</pre>
