Breaking: #68401 - SqlParser moved into EXT:dbal 

See forge#68401

Description 

The SQL Parser included with the core has not been in use by anything except EXT:dbal for some time. The SQL parser has been merged with the version in EXT:dbal which now provides parsing and compiling of SQL statements for MySQL as well as other DBMS.

Impact 

There is no impact for the core as EXT:dbal was the sole user of the SQL parser and it has been migrated into EXT:dbal.

As the parsing and the compiling of SQL statements has been separated into multiple classes the non-public interface of SqlParser has changed. Classes extending SqlParser need to be adjusted to the new interface.

Affected Installations 

Installations with 3rd party extensions that use TYPO3CMSCoreDatabaseSqlParser.

Migration 

Update the code to use TYPO3CMSDbalDatabaseSqlParser instead of TYPO3CMSCoreDatabaseSqlParser or install EXT:compatibility6 which maps the old class names to the new ones in EXT:dbal.
