00dc3068fe Implement the lazy caching mode. Rows are stored in the buffer while fetching forward. 
The switch to the fully cached mode is performed upon the first positioned access.

11495a55fb Refactored the whole RSB stuff into classes. They're inside the /recsrc sub-directory now. 
Fixed the layering for WITH LOCK and (partially) ANY/ALL predicates.
Cleaned up the outdated code that never worked (mapping DISTINCT to an index, some VMS remainings).
Wiped out a lot of the pre-ODS11 optimizer logic. Some minor adjustments there.
Re-implemented the full outer join from scratch. This resolves CORE-2678 (full outer join cannot use available indices).
Resolved CORE-2796: DB_KEY is always zero for external tables.
Implemented the core part of the scrollable PSQL cursors. Implementation is still incomplete, but ready for testing.
Some other changes I don't recall at the moment ;-)

WARNING! The engine may be unstable. Please email me about any issues found.
