Make aoTuv the libvorbis shipped in Ubuntu

[Ryan]

Binary package hint: libvorbisenc2

Ubuntu ships with full support for the popular, free software, and unpatented Vorbis codec by default.

This is good, however, the upstream libvorbis has not been meaningfully improved since September of 2004, when various outside patches including the "AoTuv" patch set were merged back in.

In the six years following this, there have been no patches reaching upstream relating to quality, while the AoTuv fork has been increasing in quality level significantly. The divide in quality between upstream (Xiph.org) and AoTuv is also widening over time, and has reached the point where a side by side comparison of the two reflects very badly on the official upstream Vorbis encoder, particularly but not limited to the lower quality settings.

In order to best serve the needs of the Ubuntu community at large, I propose replacing the upstream libvorbis packages with packages with AoTuv integrated.

License: BSD

Scope: Three packages will be changed due to this. libvorbisenc2, libvorbisfile3, libvorbis0a

Benefit to Ubuntu: Ubuntu ships with the highest quality Vorbis implementation available.

User Experience: "Hmm, this sounds better for some reason." "Wow! Now I can use lower quality settings and save on my monthly bandwidth bills for streaming!" User interface for using Vorbis remains unchanged as the patches affect only the backend which the users don't interact with anyway. All frontend utilities work as if nothing happened.

https://launchpad.net/~towolf/+archive/codecs - PPA for Tobias Rolf, which has carried AoTuV packages with the functionality I have outlined for some time now. Patching around limitations in Ubuntu with external packages is clearly suboptimal and not conducive to a good user experience. (Much thanks to Tobias Wolf for maintaining these though! They are tremendously helpful.)

Note: I'm currently on Lucid Lynx development, and have had to "downgrade" and version lock my Vorbis packages to Mr. Wolf's PPA for Karmic.
