4c4a77a4fe Refactored SQZ into a class. Fixed all the SCHAR* pointers to be UCHAR* + appropriate cleanup. 
Make the interface and internals friendly to any byte sequence, even the one longer than 32K.

ce9fd62c3c Swept flag implementation. 
A little optimisation of mark_full() - don't call it if not necessary, don't mark PP if its flags already matched to DP flags.

8c757b0f30 ODS change : implement dpg_secondary flag. 
Other : make table scan skip secondary data pages, propagate record type to the store_big_record to allow record head be stored at the primary record page.

559494bfd3 A couple of ODS changes : 
- abandon page checksums and use page number for validation
- PIP have now pip_used field to track number of allocated pages
- two more flag bits per data page is now reserved on pointer page. One is for the swept flag and second is still not used but makes calculations easy
- misc changes
Don't forget to rebuild your DBs !

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.

dimitr
1a943d1990 Splitted the undo log into two parts: in-memory one for initial undo items (but they're much more dense now) and on-disk (cached up to TempSpaceLimit) one for full record versions (used in update-in-place). 
This dramatically reduces the memory usage for bulk updates, thus solving CORE-1575 (serious memory bug on multiple update a table in a single transaction) and CORE-1477 (Avoiding excessive memory consumption by undo-log after series of updates) and predicting out-of-memory conditions that could often lead to record-level corruptions.

39896cb955 Fixed CORE-1671: atexit() calls in client libraries cause segfaults

To do it:
- created new template GlobalPtr, controlling access to destructors of global objects.
- applied it to global objects.

Also some related cleanup.
