- Got rid of the fixed array that kept the stream count in the first element and 255 streams after it.
...
- Changed streams from UCHAR to ULONG as Dmitry wanted
- Got rid of some redundant flags to indicate BLR level
- Misc changes (for example, converted to test for DBB_read_only in Database to a function)
- BLR v6 is left commented (waiting for a better solution to appear, if any exists)
- This change is not going to raise the engine limits until a solution is found to express more than 255 streams in BLR.

Splitted the undo log into two parts: in-memory one for initial undo items (but they're much more dense now) and on-disk (cached up to TempSpaceLimit) one for full record versions (used in update-in-place).

This dramatically reduces the memory usage for bulk updates, thus solving CORE-1575 (serious memory bug on multiple update a table in a single transaction) and CORE-1477 (Avoiding excessive memory consumption by undo-log after series of updates) and predicting out-of-memory conditions that could often lead to record-level corruptions.
