[arch-dev-public] Do not update packages that are part of the C++11 ABI change rebuilds

[Evangelos Foutras]

Reposting this with the main point in the title since some updates made
their way into [community]; see Allan's message for details. [1]

Doing minor version bumps in [staging]/[community-staging] is fine,
however, the repo hierarchy needs to maintain monotonic versioning
(can't have newer packages in the stable repos compared to staging).

The following packages will be redone automatically at the end of the
current rebuilds:

mediainfo      =>  [trunk]  0.7.80-1  !=  0.7.79-2  [staging]
atanks         =>  [trunk]  6.3-1     !=  6.2-2     [staging]
mediainfo-gui  =>  [trunk]  0.7.80-1  !=  0.7.79-2  [staging]
libmediainfo   =>  [trunk]  0.7.80-1  !=  0.7.79-2  [staging]
