jack 0.80.0

[Junichi Uekawa <dancer@netfort.gr.jp>]

Jack 0.80 has been released, and some apps that requires 0.80 
(like ecasound 2.3) have already come out.

I'm not quite sure of the binary compatibility; it should 
somehow work. 

Status of current jack is that currently it compiles on all arches, 
but actually runs on 
  ia64, i386, x86_64
only (to my dismay, which I found by running on my Zaurus PDA).

Therefore, we probably only need to consider binary compatibility 
with previous versions of ia64, and i386 packages.
