common.sh parsing for api10 arguments

If OS_API_VERSION has value 10 we'll check and parse the arguments using
the version 10 style, as described by the relevant design doc, and save
them to the old names we used before. This makes the create and rename
scripts version 6 compatible (except for bugs, that is), while import
and export will need some more work.
