Backported 4.1 charset field info changes from Connector/J 3.1.

Fixed Statement.setMaxRows() to stop sending LIMIT type queries when not needed (performance).

Fixed DBMD.getTypeInfo() and DBMD.getColumns() returning different value for precision in TEXT and BLOB types.

Fixed SQLExceptions getting swallowed on initial connect.

Fixed ResultSetMetaData to return "" when catalog not known. Fixes NullPointerExceptions with Sun's CachedRowSet.

Allow ignoring of warning for “non transactional tables” during rollback (compliance/usability) by setting ignoreNonTxTables property to true.

Clean up Statement query/method mismatch tests (that is, INSERT not permitted with .executeQuery()).

Fixed ResultSetMetaData.isWritable() to return correct value.

More checks added in ResultSet traversal method to catch when in closed state.

Implemented Blob.setBytes(). You still need to pass the resultant Blob back into an updatable ResultSet or PreparedStatement to persist the changes, because MySQL does not support “locators”.

Add “window” of different NULL sorting behavior to DBMD.nullsAreSortedAtStart (4.0.2 to 4.0.10, true; otherwise, no).
