[Bug 49203] Should check blank cd size before decoding files

[Amos Brocco]

Public bug reported:

As the decoding process is slow (see bug #49202 ), Serpentine should check
the blank cd available space/time before decoding files, and not at the end.

Also, if the media is too small (ex. 74min cd instead of 80min) the
decoded files should not be immediately erased, but a "Retry" button
should be offered (so that the user can change the media and retry
without having to wait another time for the files to be decoded)

** Affects: serpentine (Ubuntu)
     Importance: Untriaged
         Status: Unconfirmed
