This change introduces a new GetTableStatus method on DeviceMapper,
which returns a vector of information about each target in a device's
table. Some target types (such as verity) can also return additional
information as a string.
Support for this call has also been added to the "dmctl" tool via a
"table" command. Examples:
$ dmctl create blah zero 0 8000 linear 8000 1000 /dev/block/sdd1 0
$ dmctl table blah
Targets in the device-mapper table for blah:
0-8000: zero
8000-9000: linear
For verity:
sailfish:/ # dmctl table system
Targets in the device-mapper table for system:
0-4128792: android-verity, V
Bug: 110035986
Test: libdm_test gtest; AVB1 device still boots
