1) Fixed CORE-1696 - "Deadlock in LM by using nbackup utility" with priority rating of lock requesting for LCK_backup_database and LCK_bdb.
2) A lot of stability fixes were made.
3) The key thing is using new GlobalRWLock for removing LCK_set_owner_handle function and speed up performance.
4) The code is still ready for using both in shared cache architecture and in claster architecture.
related with local events from isc_sync.cpp.
2. Cleanup - removed unused parameter 'number of events' from ISC_event_wait()
and two unused parameters from ISC_event_init().
3. Added SYSV-semaphore based implementation of IPC to isc_sync.cpp.
This should fix CORE-2102: Firebird 2.5 does not build on MacOS (Darwin).
4. Fixed use of posic CS without (x)inetd (i.e. fb_inet_server -s).
5. Fixed (to be reviewed by Dmitry) recovery after some process death in lock manager.
- do not write pages of temporary tables to the NBAK delta files (engine still does a lot of unneeded locking and synchronization for temp pages, especially in CS builds, but this is another problem)
- refactor and clean up potential problems in the logic of dirty page -> clean page transition
- obsolete items like WAL and JOURNAL (cleaned in the past)
- crud from attempts never finished like the shared cache manager for Classic
- DSQL nodes that aren't used. This allowed freeing some keywords.
The functionality was disabled by commenting the code. No code has been deleted.
- old implementation is still in place and can be turned on (see BALANCED_DIRTY_PAGE_TREE macro)
- both implementations are unconditional to keep them in sync until the old one is dropped completely
2) Increased MAX_PAGE_BUFFERS to 128K (2GB for 16K page size)
PandoraBox* pbox = reinterpret_cast<PandoraBox*>(&can_of_worms);
pbox->open();
pbox->flush();
Nickolay may want to undo my ods.h changes if gcc insists
in its crusade against non-PODs and poodles.

alice's STR -> alice_str*

etc.
It creates entities and backups and restores for me. :-)
