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;

Simplify DSQL removing a lot of copy-and-paste and recursion that change some parameters some times.
...
Some assertion errors may have been introduced. It would be easy to revert them.

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).

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.
