IMPALA-3201: in-memory buffer pool implementation

This patch implements basic in-memory buffer management, with
reservations managed by ReservationTrackers.

Locks are fine-grained so that the buffer pool can scale to many
concurrent queries.

Includes basic tests for buffer pool setup, allocation and reservations.
