py3: convert hg executable path to bytes in missing case in procutil We (Google) noticed this in our tests when we use chg and a hg wrapper script not called 'hg'. The executable then ended up being a native string, which then failed in chgserver when trying to convert the environment dict to a byte string.

py3: make statprof's chrome output work With this patch, this command works: python3 hg --profile --config profiling.statformat=chrome st (and it works with s/python3/python2/ as well) Differential Revision: https://phab.mercurial-scm.org/D6777

py3: for statprof's Chrome output, write json to string, then encode to bytes `json.dump(obj, fp)` requires `fp.write()` to accept str output, and since the file pointer we have there only accepts bytes, we need to change to json.dumps() and then encode as utf-8. We have already done the same thing for the json (non-Chrome) format in 4b7eb862692e (py3: encode json output to bytes and use write(), 2018-10-12).

upgrade: make sure we reclone all revlogs when updating to some format Adding or removing some requirement (eg: sparserevlog), requires to reclone revlog to use the new format. We cannot simply copy the original files. In this case, we issue a warning to proceed with clone every revlogs.

upgrade: add an argument to control changelog upgrade Same as for `--manifest` we can now select more selection.

upgrade: add an argument to control manifest upgrade The argument can be used to only "clone" manifest revlog or clone all of them but this one. The selection will make more sense once we have a `--changelog` flag in the next changesets.
