commands: rename clone --uncompressed to --stream and document --uncompressed isn't a very good name and its description in the help documentation isn't very useful. We refer to this concept as "stream clones" in a number of places. I think it makes sense to change the user-facing argument to use the mode --stream. So this commit does that. We keep --uncompressed around for backwards compatibility. While we're here, we overhaul the help docs for streaming clones to be somewhat useful. All tests have been updated to reflect the new preferred --stream argument. A test for backwards compatibility of --uncompressed has been added. .. bc:: `hg clone --stream` should now be used instead of --uncompressed. --uncompressed is marked as deprecated and is an alias for --stream. There is no schedule for elimination of --uncompressed. Differential Revision: https://phab.mercurial-scm.org/D864
