Sets the maximal allowed number of threads for @pool.
A value of -1 means that the maximal number of threads
is unlimited. If @pool is an exclusive thread pool, setting
the maximal number of threads to -1 is not allowed.
Setting @max_threads to 0 means stopping all work for @pool.
It is effectively frozen until @max_threads is set to a non-zero
value again.
A thread is never terminated while calling @func, as supplied by
g_thread_pool_new(). Instead the maximal number of threads only
has effect for the allocation of new threads in g_thread_pool_push().
A new thread is allocated, whenever the number of currently
running threads in @pool is smaller than the maximal number.
@error can be %NULL to ignore errors, or non-%NULL to report
errors. An error can only occur when a new thread couldn't be
created.
Before version 2.32, this function did not return a success status.
