Improve disc size reporting. The current discsize thats reported is the
current recorded extent and not the complete maximum extent of the disc.
An empty CD/DVD disc is seen as having an invalid length and given 800 Mb
size. This makes it possible to write to a CD-R using `dd' as some tend to
However when an extent is recorded the initial recorded length is seen as
valid and is thus set as absolute upperbound to read and write actions
preventing extention of the disc.
