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.

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.

Fix the discordant data types between flags and the vars used to work with them (really dangerous if the flag is USHORT and you hold it in a UCHAR). Also, get rid of some debris of the uppercased typedefs.

Nickolay may want to undo my ods.h changes if gcc insists
in its crusade against non-PODs and poodles.

Enhanced Index Structure.
...
1) NULLs on top when sorting on ASC index, DESC stays the same.
2) Support for larger index lengths, can be up to 1/4 page size.
3) Store record-number on non-leafpages for faster lookup in many duplicates.
4) Jump-nodes for faster key-lookup in index on larger page-sizes.
5) Segment selectivity calculation added.
