[PATCH 4/6] fms: Support the DVD/BD images size over 2.1Gb

[Igor Kononenko]

Adds the ability to use the FMS image size greater than 2.1Gb.  This
limitation is due to the maximum number of available frames on the
CD-ROM media.

An incoming implementation of additional media formats (DVD-ROM, BD-ROM)
should support both formats' possible capacity.

End-user-impact: Now, the FMS able to use a medium-image backend  file,
                 which size is more significant than 2.1Gb
