Add a drain hook to each pool. This hook is called in three cases.
1. When a pool hit the hard limit. Just before bailing out/sleeping.
2. When an allocator fails to allocate memory (with PR_NOWAIT).
3. Just before trying to reclaim some page in pool_reclaim.
The function called form the hook should try to free some items to the
pool if possible.
Convert m_reclaim hooks that were embedded in MCLGET, MGET and MGETHDR
into a pool drain hook (making the code much cleaner).
