/** Format media for use with libburn. This currently applies to DVD-RW
in state "Sequential Recording" (profile 0014h) which get formatted to
state "Restricted Overwrite" (profile 0013h). DVD+RW can be "de-iced"
by setting bit2 of flag. DVD-RAM and BD-RE may get formatted initially
by setting bit4 of flag. DVD-RAM and BD-RE may get formatted initially
or re-formatted to adjust their Defect Managment.
This function usually returns while the drive is still in the process
of formatting. The formatting is done, when burn_drive_get_status()
