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.

2b87e94242 Use explicit iterators instead of the implicit (built-in) ones due to the thread-safety requirements. 
This change affects GenericMap only, as it's used globally in a few places and we have a proven crash there.
I have a more complete solution (total cleanup of default accessors from BePlusTree and SparseBitmap) in my local tree (thanks to Dmitry Kovalenko), but it's incomplete (requires more changes inside the engine) and IMHO risky (~20 core modules are affected), so I'd like to defer finalization of this cleanup till v3.0.
All objects of these types seem being protected by dbb_sync, so they shouldn't cause us any problems currently.

0a9e8c8382 Implemented CORE-1751. The changes include: 
1) Make memory counters aggregated.
2) Add attachment pool and allocate appropriate resources out of this pool.
3) Always release attachments explicitly (via destructor).
4) Always delete user requests prior to attachment deletion.
5) Introduce memory usage counters per every monitoring object.
6) Misc refactoring.
Some pieces are still incomplete (although everything basically works), but I'd like to get feedback and testing sooner rather than later.

58d381edd7 1. Remove blr_src_info code as it is prevents database downgrade from ODS 11.1 
2. Put debug information (mapping between blr offset and source line\column and names of local variables) into new blob field RDB$DEBUG_INFO
This is first step to implement native SQL debugger i believe

af8ecc26ca Solve three problems with arrays: 
- Don't allow to apply scalar/subscript syntax to fields that aren't array.
- Detect if we get corrupt database containing array with more than 16 dimensions.
- Reject attempt to subscript array with more than 16 dimensions and thus fix the buffer overrun.
