When I removed the __ from the 'private' symbols exported, this
internal driver typedef now clashes with the following public
symbol:

The DrvDrv looks a little odd, but it is actually consistent with
the naming for driver.h, which is basically s/vir/virDrv/ against
the public API :-)

Yeah, that'd be a reasonable thing todo - just add .1 to the existing
version. If we end up adding lots of new symbols, it'll be fairly obvious
that we should increment a major version number instead.
