Change subject: Headers and reservation logic for daemon-wide buffer pool
......................................................................


Patch Set 3:

This is an initial commit building the buffer pool off to the side of the rest 
of Impala. I think it will be easiest reviewing the work in chunks: in a later 
commit we can switch over operators to using the pool.

I started prototyping the switch for aggs and joins and was able to run some 
non-trivial queries.

Compared to the previous patchset I posted, the reservation tracking is split 
out from the pool and the locking is much simpler. There are many other small 
changes and improvements.
