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

1. Reworked internal_info implementation in both DSQL and JRD.
...
New helper class created to serve it properly.
2. Added exception re-raise semantics.
Syntax: EXCEPTION;
If there was handled exception, re-initiate it, otherwise evaluate to no-op.
3. Implemented run-time exception messages.
Syntax: EXCEPTION <exception_name> [<value>];
If <value> is specified, evaluate it and use instead of RDB$EXCEPTION_MESSAGE.
4. Added new SQLCODE and GDSCODE system variables.
Available in procedures/triggers only.
If there wasn't any exception raised, return zero (success), otherwise return an error code.
5. Implemented ROWS_AFFECTED system variable.
Available in procedures/triggers only.
Count rows affected by the last INSERT/UPDATE/DELETE statement.
For any other statement, result is always zero.
