dc03621e9d fix(rowgroup): RGData now uses uint64_t counter for the fixed sizes columns data buf. 
The buffer can utilize > 4GB RAM that is necessary for PM side join.
	RGData ctor uses uint32_t allocating data buffer.
 	This fact causes implicit heap overflow.

1f190a6e75 MCOL-5477 Disk join step improvement. 
This patch:
1. Handles corner case when the bucket exceeded the memory limit, but we cannot redistribute the data in this bucket into new buckets based on a hash algorithm, because the rows have the same values.
2. Adds force option for disk join step.
3. Add a option to contol the depth of the partition tree.

e09d24cb8d [MCOL-5265] Change boost:shared_ptr to std::shared_ptr. 
This is attempt to make some part of the code more stable.
For some reason we can get a spurious nullptr for boost::shared_ptr
which cause an assert and abort.

d3bc68b02f MCOL-641 Refactor initial extent elimination support. 
This commit also adds support in TupleHashJoinStep::forwardCPData,
although we currently do not support wide decimals as join keys.

Row estimation to determine large-side of the join is also updated.

Re-added the mutex lock, but after risk of double lock grab.

a55495a73f MCOL-3713 - A UM join mem overflow abort bug 
Seems that segregateJoiners would double-lock a mutex.  Not sure why
we're only seeing it now.

This is a checkpoint commit, probably not final for this bug.

80ff0bfa56 Fixed a couple minor things I ran into working on another task 
- Made TupleUnion not allocate 64MB per frame.
 - Saw a crash, where a THJS would be destroyed w/o being used.
   Fixed the bad reference.
