VariableSizeFrame(VSizeFrame) support for Hyracks.

This patch replaced Frame/Accessor/Appender with the new API which

supports BigObject.

The ExternalSorter/TopKSorter/ExternalGroupSorter

have been implemented to support big object.

The Groupby && Join should work with BigObject also. But it will break the

memory budget when it encounter a big object. I will fix the memory

problem later in a separate CR.

The design about the frame allocation is

Suggest review order:

Patch 12: It includes all of the sorting operators.

Patch 13: It applys the new IFrame API to all Hyracks codes.

Patch 14: Some bug fixes to pass all Asterix's tests.

Patch 15: Skip it!

Patch 16: Some bug fixes to the Asterix's tests in small frame setting.

Later Patch: address the comments
