3) Reject NULL if no indicator specified.
4) Improve the handling of '_' in table name.
5) Unify internal begin/commit/abort operations.
6) Change SQLTables() to return null not "" for the
   table_owner.
7) Fix a bug about parameter handling reported by Benoit Menendez.
8) Add cast in handling ODBC date/time escape sequences.
9) Fix a bug about cache_size handing in declare/fetch mode.

[ODBC3.0 related]
10) Improve the handling of descriptor handles(ODBC3.0).
11) Improve the type handling of some types for ODBC3.0.

[Thanks to Marcelo Aceto for his useful patches]
