/** Program isoburn_disc_get_msc1() to return a fabricated value.
This makes only sense between aquiring the drive and reading the
image. After isoburn_read_image() it will confuse the coordination
of libisoburn and libisofs.
Note: Sessions and tracks are counted beginning with 1, not with 0.
@since 0.1.6
@param drive The drive where msc1 is to be set
@param adr_mode Determines how to interpret adr_value and to set msc1.
If adr_value shall represent a number then decimal ASCII
digits are expected.
0= start lba of last session in TOC, ignore adr_value
1= start lba of session number given by adr_value
2= start lba of track given number by adr_value
3= adr_value itself is the lba to be used
4= start lba of last session with volume id
given by adr_value
@parm adr_value A string describing the value to be eventually used.
@param flag Bitfield for control purposes. Unused yet. Submit 0.
