PartialVolume 2acaff5c3f Multiple loop device test mode for developers & testers. ...

The main purpose of this commit is to allow the developer
or tester the ability to specify /dev/loop0 .. /dev/loopn on the
kernel command line in /boot/grub/grub.cfg and /EFI/BOOT/grub.cfg
where n is unlimited, although it is recommended that no more
than 20-30 loop devices are specified. The loop devices are of a
fixed size alternating between 500Kbytes and 1 MByte in size. Due
to their small size you would typically select 500 or 1000 rounds
when testing. To create loop devices append the following to
grub.cfg nwipe_options='--nousb /dev/loop0 /dev/loop1 ... /dev/loopn'
loop devices should be sequential starting at loop0, any break in
the sequence will cause creation of loop devices to stop.

This commit also includes a ffmpeg module
+BR2_PACKAGE_FFMPEG_SWSCALE=y for creation of
videos of the display. This may be useful for creating
training material, youtube videos etc using the command
ffmpeg -f fbdev -framerate 30 -i /dev/fb0 output.mp4

Initial work was started on excluding the boot disc if
the following shredos_exclude_boot_disc is appended
to the kernel command line.
