Refactored the conjuncts handling code in the optimizer to be simpler and avoid duplication. As a side effect, this also fixes CORE-4365: Equality predicate distribution does not work for some complex queries. Cleanup up some legacy checks that I consider unnecessary.

- 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.
