Include platform definitions file common.h in firebird.h. Use OS-specific ThreadId instead artificial FB_THREAD_ID, avoiding unneeded casts in the code. This should fix BSD and MAC ports.

I believe this flag is redundant as it duplicates the information already available on the index root page.

Slightly refactored the b-tree nodes. This commit includes cleaning up ods.h from the runtime (in memory) structures and encapsulating the b-tree nodes implementation inside their corresponding objects. To be continued.

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Cleaned up the outdated code that never worked (mapping DISTINCT to an index, some VMS remainings).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 ;-)
