Support feature branches in branch-stx.sh
This changes branch-stx.sh to not assume that a manifest file will be used to create the list of repos to process, and allow direct repo URLs on the command line. Change-Id: Ie2bbfa314b33d2b2b810ee479b4a0158e9d819bf Signed-off-by: Dean Troyer <dtroyer@gmail.com>
