    mem-pool: track and verify initialization state

    It is possible that pthread_getspecific() returns a non-NULL value in
    case the pthread_key_t is not initialized. The behaviour for
    pthread_getspecific() is not defined in this case. This can happen when
    applications use mem-pools from libglusterfs.so, but did not call
    mem_pools_init_early().

    By tracking the status of the mem-pools initialization, it is now
    possible to prevent calling pthread_getspecific() in case the
    pthread_key_t is not initialized. In future, we might want to exend this
    more to faciliate debugging.
