Adds support in the BE AnalyticEvalNode for ROWS windows with arbitrary
start bounds. If there is a start bound specified a sliding window must
be maintained. As input rows are processed they are added to the window.
As they expire from the window, they are 'removed' from the current
intermediate state of the evaluators (stored in curr_tuple_) by calling
AggFnEvaluator::Remove(). This is an initial implementation that keeps
the tuples in the window in memory. We can improve this later by using
the BufferedTupleStream with an Iterator interface supporting multiple
readers.
This also fixes IMPALA-1253: LAST_VALUE returns incorrect results

We weren't returning the right merge function for decimal in
GetAvgFunction(). Someday the functions will be registered in the FE
like for scalar functions.

Float/Doubles are lossy so using those as the default literal type
is problematic.
