superproject: support a new revision attribute.
Tested:
$ ./run_tests
Verified that a manifest that specified superproject revision would use
the specified revision, and superproject will use the default revision.
Note that this is a slight behavior change from earlier repo versions,
which would always use the branch name of the manifest itself. However,
the new behavior would be more consisitent with regular "project"
element and would allow superproject be used even if it is not enabled
for the particular manifest branch, so we have decided to make the
change as it would provide more flexibility and better matches what
other elements would do.
