Merged, I did some changes to the code. The most visible change is
that loopcxt_find_overlap() (originally loopcxt_check_conflict())
returns info about full match (offset and sizelimit matches).
This allows to use just one iteration (loopdevs scan) in mount(8) to
check for overlaps as well as to found device to re-use.
All works as expected, but re-test if you can :-)
Tomorrow I'm going to work on the losetup patches.
