The official package name *is* libmysqlclient-dev; there is no
libmysqlclient16-dev, even as a provided virtual package name. I
suspect specifiying
libmysqclient-dev (>= 5.1), libmysqlclient-dev (<< 5.2~)
would have the desired effect, though.

Oops, good point. As I understand it, any backward-incompatible
changes were at the ABI level, and so should only have broken anything
that had to hardcode details of structure layouts and the like, a set
that unfortunately turns out to include gnade at present. :-/

Automatically picking up structure layout and call details from C
headers definitely sounds like the way to go.

I'd just compare the headers to see how the relevant declarations
changed.
