Correction for CORE-1550: Unnecessary index scan happens when the same index is mapped to both WHERE and ORDER BY clauses.

Also resolved CORE-1846: Allow index walk (ORDER plan) when there's a composite index {A, B} and the query looks like WHERE A = ? ORDER BY B.

- avoid unneeded h-file dependencies, making boot build engine dependent

- 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.
