Hi!

Nick Hudson <skrll@netbsd> recently updated pth to 2.0.0
but ran out of time, so I finished the PKGREVISION bump work
that was made necessary because of the pth library major bump.

I hope I got all dependency of pth, and only the necessary ones.
Some where bumped because they had optional dependencies (e.g.,
lame).

Please send-pr(1) or mail me if I overlooked anything or
a PKGREVISION line is in an incorrect place.

Thanks,
 Thomas
