Proposing new USE_ knob for p5-DBD-mysql*

[Chris Rees]

Hi Sergey and Alex,

Problem: p5-DBD-mysql[45][0-5] ports are a pain to depend upon in a
port, because of the need to differentiate between the mysql versions.

I've thrown together [1] as an example of how we could approach
this... I've had to put this logic into sympa, and it looks a common
problem unless I've missed something obvious.

Anyone have any opinions or better ideas?
