70d5ebdfdf - 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.

- it doesn't make sense to return -1, as the result is void* with PTHREADS

ed0e0daeb3 - External Engines implementation. 
- Plugins API.

- Feature CORE-2700 - UDR (User Defined Routines) Engine - C++ API supporting functions, triggers and stored procedures.
- Feature CORE-2470 - Support for alternate format of strings literals.
- Feature CORE-2310 - DDL triggers.
- Feature CORE-2312 - PSQL Packages.
- Feature CORE-1209 - CONTINUE statement.
- Feature CORE-1180 - DDL syntax to change (not) nullable state of columns.
- Feature CORE-2090 - Support OVER () clause with current aggregate functions.

- Fixed CORE-2699 - Common table expression context could be used with parameters.

- Introduce ODS 12.0.

- Work in progress in type-safe parser.
- Refactor some DDL commands (procedures and triggers) from DYN to DdlNodes.
- Refactor virtual tables to use a class hierarchy instead of namespaces. This is basic thing, not based on the changes done in Vulcan. Window functions is based on this work.
- Refactor COMMENT ON and DROP FUNCTION from DYN to DdlNodes. COMMENT ON do not use GDML anymore, it uses DSQL with PreparedStatement class.
- Refactor EXECUTE BLOCK to StmtNodes.
- Refactor the IUDF to SysFunctions. That eliminates RDB$GET_CONTEXT and RDB$SET_CONTEXT from RDB$FUNCTIONS.

1a4949891b Refactored NBackup subsystem. 
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.

e79f55708d 1. Cleanup - use Firebird::Semaphore instead of local events, removed code 
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.
