Personally I would prefer to avoid doing this. This isn't a very big
library so unlike gstreamer or gtk I think it won't take much to
switch to v2.0. If anything - I prefer a compatibility layer included
in the package where - if an option is passed to configure - the old
header would be installed alongside the v2.0 .so file + another .so
for translating the calls.

If you see a very good reason to make them both live together - let me know.
