devtool: add: add explicit srcrev/branch options

At the moment when fetching source from a git repository you have to
know that you can specify the revision and branch in the URL with
';rev=' and ';branch=' respectively, and you can also get thrown off by
the shell splitting on the ; character if you forget to surround the URL
in quotes. Add explicit -S/--srcrev and -B/--srcbranch options
(consistent with devtool upgrade) to make this easier for the user to
discover and use. (The rev and branch URL parameters will continue to
work, however.)
