[Libburn] Thoughts about writting writting progress

[Tiago Cogumbreiro]

Hi again,
I was trying to develop the writting progress for libburn, while
browsing throughout each part of the write_disc code i encountered a
minor sitback, how would i describe the progress of writting when we are
writting the lead-out and lead-in, could the user have access to
detailed status of the progress? 
On a lesser imporant issue, maybe users would like to know when they the
drive is performing lead-in/out so maybe a more detailed progress could
be implemented with a status for describing the device work.
