infinitepush: avoid using push during debugbackup Summary: `hg push` takes a lock because it updates phases and may receive other bundle2 parts from remote server. We don't need it in debugbackup. And since debugbackup is intended to run in background we want to avoid taking locks. Instead let's use raw `unbundle()` wireproto method and disable pushback bundle2 parts.

codemod: import from the edenscm package Summary: D13853115 adds `edenscm/` to `sys.path` and code still uses `import mercurial`. That has nasty problems if both `import mercurial` and `import edenscm.mercurial` are used, because Python would think `mercurial.foo` and `edenscm.mercurial.foo` are different modules so code like `try: ... except mercurial.error.Foo: ...`, or `isinstance(x, mercurial.foo.Bar)` would fail to handle the `edenscm.mercurial` version. There are also some module-level states (ex. `extensions._extensions`) that would cause trouble if they have multiple versions in a single process. Change imports to use the `edenscm` so ideally the `mercurial` is no longer imported at all. Add checks in extensions.py to catch unexpected extensions importing modules from the old (wrong) locations when running tests.

codemod: join the auto-formatter party Summary: Turned on the auto formatter. Ran `arc lint --apply-patches --take BLACK */.py`. Then run `arc lint` again so some other autofixers like spellchecker etc. looked at the code base. Manually accept the changes whenever they make sense, or use a workaround (ex. changing "dict()" to "dict constructor") where autofix is false positive. Disabled linters on files that are hard (i18n/polib.py) to fix, or less interesting to fix (hgsubversion tests), or cannot be fixed without breaking OSS build (FBPYTHON4). Conflicted linters (test-check-module-imports.t, part of test-check-code.t, test-check-pyflakes.t) are removed or disabled. Duplicated linters (test-check-pyflakes.t, test-check-pylint.t) are removed. An issue of the auto-formatter is lines are no longer guarnateed to be <= 80 chars. But that seems less important comparing with the benefit auto-formatter provides. As we're here, also remove test-check-py3-compat.t, as it is currently broken if `PYTHON3=/bin/python3` is set.
