Ben Gras d3e3c78051 testmfs, testisofs: MFS format, ISO functionality
testmfs: catch MFS format changes

This test tests mkfs.mfs will generate the same FS image given the same
input files. mkproto creates a proto file (normalizing directory entry
order). The assumption is that a change in the output flags a tacit
change in FS format, and that a FS format change will cause the image
to change.

        . Changes to mkfs.mfs that innocently change the format can
          change the sha1 output in the script along with it.
        . The assumption is that corresponding versions of mkfs.mfs and
          MFS will always work together; otherwise a lot breaks (ramdisk etc.)
        . Therefore, as long as a generated FS image stays the same with the
          same input now, incompatible MFS changes will still be flagged,
          even if they work together with the current mkfs.mfs.

testisofs: test ISO filesystem

        . to test isofs: prepare an ISO FS image using writeisofs, copy it
          to a RAM device, mount it using the iso9660fs server, compare the
          SHA1 contents of the files on the ISO with the inputs.
        . use su to run certain commands in the script as root

run script: run shell script tests

	. they are installed without .sh so should be
	  searched for as such
	. add diagnostic when tests are skipped
