[apparmor] AppArmor release versions

[John Johansen]

The use of ~beta1, ... in our release versions has proven to be problematic from
both a packaging and repository mirroring pov.  To address this it has been
proposed we move to a new format relying solely on numbers.

The proposal is the next development release moves to a

  2.7.0.99.xx  format

and when the release comes the major versioning numbers will be bumped. ie.
  2.8.0 or even 3.0.0

The specifics of how betas for point releases will be handled has not been
worked out yet.
  2.7.1.xxx will not work for 2.7.1 bump a 2.7.0.50.xxx or something would.


So far no changes have been made, so any feedback on the proposal is welcome.
