bundlerepo: drop the `baserevision` hack It is not used anywhere anymore, so we can safely drop it.

bundlerepo: simplify code to take advantage of `_rawtext` In the revlog code, the code getting the raw text is now isolated. We take advantage of this to simplify the bundlerepo code.

py3: use pycompat.maplist() in chgserver test-chg.t almost passes on py3 after this patch. Differential Revision: https://phab.mercurial-scm.org/D6771

run-tests: handle --local before --with-hg We no longer support them both together, so this is now safe to do. By checking --local first, we avoid error out about an invalid --with-hg script if --local was also given (we instead tell the user that the options are mutually exclusive). I also had to wrap the 'binpath' we pass to setattr() in _strpath() to keep `python3 run-tests.py -l` working. That change also made `python3 run-tests.py -l --chg` work, which was the reason for this series. Differential Revision: https://phab.mercurial-scm.org/D6760

run-tests: error out on `--local --with-[c]hg` I don't see much reason to allow these combinations. You could use --local and override only one of --with-hg or --with-chg, but I don't see much practical use for that. It would be easy to work around anyway by passing both --with-hg and --with-chg. By erroring out, it makes the code a bit easier to reason about to allow the next few patches. Differential Revision: https://phab.mercurial-scm.org/D6759

contrib: simplify the genosxversion.py command to find the hg libraries I forget what problem I ran into while trying to teach the makefile to use a non-system python. (It might have ben missing hg-evolve and/or keyring, but `check_output()` was raising an error.) This still isn't great because it will return non zero for something like the username not being set, even though we aren't asking for it. But I suppose it's still useful to simplify.

interfaceutil: move to interfaces/ Now that we have a dedicated folder for interfaces, let's move interfaceutil there. Differential Revision: https://phab.mercurial-scm.org/D6742

interfaces: create a new folder for interfaces and move repository.py in it I was trying to understand current interfaces and write new ones and I realized we need to improve how current interfaces are organised. This creates a dedicated folder for defining interfaces and move `repository.py` which defines all the current interfaces inside it. Differential Revision: https://phab.mercurial-scm.org/D6741

python-zstandard: apply big-endian fix (issue6188) This is a port of commit d4baf1f95b811f40773f5df0d8780fb2111ba6f5 from the upstream project to fix python-zstandard on 64-bit big-endian.

exchange: abort on pushing bookmarks pointing to secret changesets (issue6159) Until now, if there is a bookmark points to a changeset which is in secret phase, hg will push the bookmark, but not the changeset referenced by that bookmark. This leaves the server bookmarks in a bad state, because that bookmark now points to a revision that does not exist on the server. This patch makes hg to abort on such cases.

packaging: add Bullseye, remove Jessie Jessie is oldoldstable now, and Bullseye is going to be the next stable (now testing). We're continuing to support the current oldstable, stable and testing releases. Differential Revision: https://phab.mercurial-scm.org/D6762

packaging: add Cosmic and Disco, remove Trusty and Artful - Trusty was publicly supported until 2019-04-30 - Artful was publicly supported until 2018-07-19 - Cosmic was publicly supported until 2019-07-18 - Disco will be publicly supported until 2020-01 Cosmic is officially out-of-date, but since it still may be in use, and because we didn't add it when it first came out, I think it would be nice to support it until the next time somebody decides to update this list of Ubuntu releases.
