histedit: rename variables so they have "ctx" in them It is convention for context instances to end with "ctx." Until we have type annotations, this makes auditing much, much easier. Differential Revision: https://phab.mercurial-scm.org/D2425

templatekw: use ctx.rev() instead of casting context to int basectx has __int__ implemented. Per mailing list discussion with Yuya, we don't like having this implemented because it is too much magic and in some cases rev() will return None, which isn't an int. So convert a `'%d' % ctx` to ctx.rev() instead. Differential Revision: https://phab.mercurial-scm.org/D2423

py3: fix handling of keyword arguments at more places The keys of keyword arguments of Python 3 should be str, which is why we need to prevent getting the b'' prefix added by the transformer or convert keys to str using pycompat.strkwargs() Differential Revision: https://phab.mercurial-scm.org/D2420

setup: only allow Python 3 from a source checkout (issue5804) People are running `pip install Mercurial` with Python 3 and that is working because not everything performs a Python version compatibility check. Modern versions of pip do recognize the "python_requires" keyword (https://packaging.python.org/tutorials/distributing-packages/#python-requires) which we set if using setuptools. But this isn't set nor recognized everywhere. To prevent people from accidentally installing Mercurial with Python 3 until Python 3 is officially supported, have setup.py fail when run with Python 3. But don't fail if we're running from a source checkout, as we don't want to anger Mercurial developers hacking on Python 3 nor Mercurial's test automation running from source checkouts. People running setup.py from source checkouts could still fall through a Python 3 crack. But at least the `pip install Mercurial` attempt will get nipped in the bud.

tests: add HTTP POST and PUT support to the $LOGDATE$ substitution The lfs serving code uses both POST and PUT requests (and there's existing support for POST).
