6de249c1c6 fixed: bug when counting nb of active threads
when queueSize > 1

also : added a test in testpool.c
       verifying resizing is effective.

166901dc72 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.

4567c57199 finalized POOL_resize()
POOL_ctx* POOL_resize(POOL_ctx* ctx, size_t numThreads)

The function may fail, and returns a NULL pointer in this case.
