Subject: [PATCH] mysqli interoperability

Hi everyone,

I'm working on an extension for an RDF triple store that is built on top
of MySQL 5+, and I'd like to be able to share the MySQL connection with
mysqli. Unfortunately, since the mysqli header isn't installed, I can't
seem to find a way that could withstand changes in mysqli.

What I've come up with is to create a trivial function which will take a
(zval *) and return a (MYSQL *). I know it's a bit of a hack, but I was
trying to be as unintrusive as possible.

Patch is attached.
