changed POOL_resize() return type to int
...
return is now just en error code.
This guarantee that `ctx` remains valid after POOL_resize().
Gets rid of internal POOL_free() operation.

reduced POOL_resize() restriction
...
It's not necessary to ensure that no job is ongoing.
The pool is only expanded, existing threads are preserved.
In case of error, the only option is to return NULL and terminate the thread pool anyway.

POOL_ctx* POOL_resize(POOL_ctx* ctx, size_t numThreads)
The function may fail, and returns a NULL pointer in this case.
