In Python 3, the default encoding of source files is utf-8. The encoding
cookie is now unnecessary and redundant so remove it. For more details,
see the docs:
https://docs.python.org/3/howto/unicode.html#the-string-type
> The default encoding for Python source code is UTF-8, so you can
> simply include a Unicode character in a string literal ...
Includes a fix for the flake8 header checks to stop expecting an
encoding cookie.
Parameter and variable types in the Python domain have the
counter-intuitive behavior of matching instance methods (or likely any
other objects) rather than classes, e.g.:
```python
class Foo(object):
def list(self):
"""List some things."""
def bar(x):
"""
:param x: x
:type x: list
"""
```
`bar()` will link to `Foo.list()` rather than the standard library
`list` type.
Moved #3465 here, to address this in `stable` instead.
This fixes a problem with the Python domain object nesting. Because only one
object name was stored in `ref_context`, and reset to `None` in `after_content`,
nesting broke if you put anything after a nested class:
```rst
.. py:class:: Parent
.. py:method:: foo()
This wouldn't resolve: :py:meth:`bar`
.. py:class:: Child
In the `after_content` method, the object is reset to `None`, so
anything after this in the same nesting is considered to be top level
instead.
.. py:method:: bar()
This is top level, as the domain thinks the surrounding object is `None`
```
This depends on #3519 and can be rebased after that is merged into stable
Fixes#3065

These are just the passing test cases for the domains currently. I am going to
patch up issues with nesting on both domains to start, so these are the test
cases I'll be testing against. I'll see about addressing the other core
domains, or at very least the cpp domain, with similar tests if this looks
okay.
So far, these tests only test against methods/functions for the basic nesting
structure. More complete tests will test additional domain roles.

* rename a few test modules to make the names more consistent
* do not copy/use Sphinx from build/ (unnecessary without 2to3)
* use a temporary dir for *all* test projects, the source tree
will stay pristine that way (default is tests/build)
* speed up tests by ~3x by splitting up test projects and avoiding
rebuilds
