manifest: remove optional default= argument on flags(path) It had only one caller inside manifest.py, and treemanifest was actually incorrectly implemented. treemanifest is still missing the fastdelta() method from the interface (and so doesn't yet conform), but this is at least progress.

py3: fully fix bundlepart.__repr__ to return str not bytes My previous fix did not fully fix the issue: it would attempt to use %-formatting to combine two strs into a bytes, which won't work. Let's just switch the entire function to operating in strs. This can cause a small output difference that will likely not be noticed since no one noticed that the method wasn't working at all before: if `id` or `type` are not-None, they'll be shown as `b'val'` instead of `val`. Since this is a debugging aid and these strings shouldn't be shown to the user, slightly rough output is most likely fine and it's likely not worthwhile to add the necessary conditionals to marginally improve it.

heptapod-ci: add a job to test the rust version of Mercurial The rust version of Mercurial is not currently tested by anything else. So it get quite important that developer runs it. Differential Revision: https://phab.mercurial-scm.org/D8017

heptapod-ci: run the --pure test too These are usually rarely run by individual developper because they are slow. However it is important that they stay happy. Differential Revision: https://phab.mercurial-scm.org/D8016
