1) Cleanup and renaming in the SCL code.

3) Added USAGE permission checks for generators/sequences and exceptions.
4) Supported USAGE in GRANT/REVOKE for all object types.
5) Refactored SET GENERATOR and ALTER SEQUENCE as true DDL. blr_set_generator is supported only for backward compatibility, it's not generated by DSQL anymore.
6) Added START WITH clause for [RE]CREATE SEQUENCE and CREATE OR ALTER SEQUENCE.
7) Fixed a number of related errors.

- 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.
