Great idea! My recommendation is to create a new sql product/dialect akin 
to mysql in sql.el and either reuse the mysql settings/variables where 
appropriate, or create defvaralias's for the mariadb variables pointing back
to the mysql variables. 

That is, reuse the font-locking and login setup, but override the prompt string.

I'd also encourage you to update the shared font-lock settings to get it 
up-to-date with the latest features. It's been a very long time since I used 
MySQL so there is some bit-rot there.

Feel free to contact me with additional questions, and Happy Hacking!

PS. If you haven't already, I'd look into getting your copyright paperwork
done so that the Emacs project can easily accept your patches.
