If a device has logical partitions but does not use a partition called
"super", we will need this to be configurable. Note that the "slot"
argument is currently unused, but will be necessary for update_engine if
there are A and B super partitions.

Test: super partition works

Note that in addition to waiting for the path to appear, we must also
wait for it to be unlinked. Otherwise, we could accidentally access an
older device when opening and closing the same partition twice in a row.

This implements getvar all by invoking each callback and writing an INFO
status for each result. For commands that take arguments, the variable
handler can specify a function that returns all possible arguments.
Currently this only applies to partition variables.

When flashing logical partitions, we read the "super" partition metadata
corresponding to the current slot. We then temporarily create a
device-mapper device for that partition, and immediately destroy the
device after all operations are complete. We do not mount partitions
ahead of time, or keep them mounted, because a fastboot operation may
change the layout of the logical partition table (or change which slot
is current).

Test: fastboot flash a logical partition under "super"
