libglusterfs: Provide a way to disable mempool effects
Problems:
- Mempool comes in the way of debugging mem-leaks/corruptions
because tools like valgrind can't detect mem-pools.
- Accessing freed pointers may crash only when the mem-pool
is completely exhausted.
Solution:
In DEBUG builds set mempool count to 0 irrespective of the
pool size requested. This should help in debugging
memory-leaks/corruptions.
