c737d6a807 Create ExprNode class hierarchy. 
Convert CONCATENATE and aggregate functions to it.

Fix some bugs:
- select sum(n) over (order by n2), sum(n) over (), n, n2 from x1;
- select (select 1 from x1 b where list(1, a.n) = 1) from x1 a;

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).

488eb40fe0 Refactor DSQL, continuing the work I started in 2.5: 
- Renamed CompiledStatement to DsqlCompilerScratch and removed inheritance to dsql_req.
- Introduced DsqlCompilerStatement, moving things from dsql_req - not completelly shareable yet.
- Make dsql_req reference a DsqlCompilerStatement. DsqlCompilerScratch may be discarded in the future.
- Replaced AlterCharSetNode usage by PreparedStatement for the default collation in database creation.
- Changed METD API.

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.

d4bf9ab246 Split dsql_req into dsql_req and CompiledStatement. This should be my last refactoring to 2.5: 
- dsql_req becomes a running request;
- CompiledStatement is derived from dsql_req. The compilation state previously in dsql_req comes to here;
- Rename many "request" parameters to "statement" where type is changed from dsql_req to CompiledStatement.
This changes makes easy the path to support compiled statement cache.
