d35f6e316b 1) Simplify the explicit plan handling between the parser and the engine. It makes no sense to pass the join type as it's ignored internally.
2) Support hash joins in the plan output and in the parser. For the latter, it's just the syntax sugar, same as loop vs merge join (see above).

e6909de7f7 Wipe out the SCROLLABLE_CURSORS code + minor cleanup.
Also, surfaced scrollability for PSQL cursors (without internal support yet).

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.

9150e6f4f2 This should fix regressions related to fixes of:
CORE-501 - Optimization problem with COALESCE
CORE-1343 - Bug with a simple case and a subquery
CORE-2041 - update or insert with gen_id() with wrong generator value

And should fix this one (snapshot build bug):
CORE-2051 - don't work subquery in COALESCE

d52dc96278 1) Move the new Node classes to appropriate files
2) Creation of StmtNode
3) Conversion of IN AUTONOMOUS TRANSACTION to InAutonomousTransactionNode (inherited from StmtNode) - it makes this feature almost self-contained

Please do a boot build or at least run blr_table.

procedures\triggers names but line\column numbers also.

3389149564 The files rng.cpp, rng.h, rng_proto.h, bookmark.cpp and bookmark.h belong exclusively to PC_ENGINE, that's obsolete functionality.
Tenth step: some code was tagged PC_ENGINE but was for SCROLLABLE_CURSORS instead, hence restore it. Also, clean unused data members, obsolete BLR verbs and the like.

09c51110b4 Added the equivalence operator. The major index optimizations are done.
Notes:
1) Some optimizations will follow after more deep analysis.
2) The syntax "==" is not yet agreed on. I'd prefer it to be changed.

ca4ea54a1e Small optimization of multiple OR booleans (or a constant IN predicate).
The idea is to use a single sparse bitmap for an index matching and hence avoid OR'ing bitmaps for every argument value.
Ported from Yaffil.
