Unfortunately, BLR compatibility is not provided, so users have to recompile their SPs/triggers.

aab2d20725 - Get rid of DBB_v3 in DSQL and put a message just in case we find ODS<=7 (impossible in theory, since FB wouldn't open such db). 
- Put mnemonics for two hardcoded error msgs I hijacked from DYN years ago. Now they are defined for the SQLERR facility.

cd413c9b8a 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.

a1bbad7ccf The entire RSE handling in the parser is slightly rewritten. New join syntax is introduced. 
Notes:
1) Some features are disabled (via isc_wish_list) yet due to their incomplete implementation.
2) The parser may become unstable or cause regressions. It will be fixed ASAP.

536d8c0552 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.
