[TYPO3-core] using t3lib_db for non-TYPO3 databases on the same host

[Martin Kutschker]

Hi!

Currently it is not possible to connect to the same db host but use another db.

Why? typo3_db uses mysql_[p]connect() using the connection pool. So any 
connect to the same server will get the same handle. Any further 
select_db() will affect the main handle of $TYPO3_DB.

I suggest a fourth parameter 'new_link' that will force a connect with 
mysql_connect($server,$user,$pwd,TRUE); which became available in PHP 4.2.

It's not urgent but a nice one for HEAD.
