IMPALA-3201: buffer pool header only

Implementation will follow in a subsequent commit.

The BufferPool interface and reservation bookkeeping are documented.

Includes documentation for some guarantees of new reservation mechanism
where reservations are always guaranteed and pages can't be pinned and
buffers can't be allocated without without a reservation. Reservations
are tracked via a hierarchy of ReservationTrackers.
