This patch annotates the `__call__` method of `PyCounter` in example: callable
objects with `#[args(args="*", kwargs="**")]`. Without it (at least in PyO3
0.15.0) the example fails with `TypeError: counter.__call__() missing 1
required positional argument: 'args'`.
* Add support for positional-only args
* Update changelog. Add a few more tests. Run rust-fmt.
* Fix test.
* Fix tests again.
* Update CHANGELOG.md to link PR instead of issue
* Update guide to mention positional-only params
* Add unreachable!() per code review
* Update and expand tests for pos args.
* Fix tests, lint, add UI tests.

* Add 'anyhow' feature which provides simple From<anyhow::Error> for PyErr impl
This makes it possible to use anyhow::Result<T> as the return type for
methods and functions exposed to Python.
The current implementation just stringifies the anyhow::Error before
shoving it into a PyRuntimeError. Conversion back to the anyhow::Error
is not possible, but it is better than nothing.

I have a use case in PyOxidizer where I want to use the
pyo3-build-config crate as a library crate so I can access the
`InterpreterConfig` struct so I can read/write config files without
reinventing the wheel.
This is doable before this commit. But it requires that the
build environment have a Python interpreter. This is undesirable
for library usage.
This commit introduces a cargo feature flag to control whether the
build script does anything. The feature flag must be present for
the build script to resolve a config. The feature flag is enabled
by default for backwards compatibility. The pyo3 and pyo3-macros-backend
crates use this feature by default, for backwards compatibility and
because it is the reasonable default.
This is probably room to conditionalize some APIs and other behavior
based on this feature flag. But we stop short of doing that for
the time being.
* Improve API docs regarding when we free memory, resolves#311

The setter function will receive a NULL value on deletion requests.
This wasn't properly handled before, leading to a panic.
The new code raises AttributeError in this scenario instead.
A test for the behavior has been added. Documentation has also
been updated to reflect the behavior.

The config header parsing code was supposed to be only invoked when
cross-compiling for Windows, but in reality it fails to correctly parse
the config header files shipped with the upstream Python for Windows.
Given that there are now better options for reliable cross-compiling
for Windows such as `PYO3_CROSS_PYTHON_VERSION` or the `abi3-py3*` features,
it should be OK to remove this config for v0.14.
Update the cross-compilation instructions section of the user guide.

* Add context manager example
A simple illustrative example on how to use context managers. I required this to use pymc3, which relies heavily on the context stack for modelling.
* Clippy changes to context example
* Extend context manager example with exit exceptions
* Context manager, s/call1/call_method1/ and comments for clarity
* Add newline to context manager section to avoid horizontal scrolling
* Change generic, potentially confusing label.
s/objects.py/house.py/
* Use call_function1 rather than call_method1.
* Missed a call_method0, change to call_function0
* Update guide/src/python_from_rust.md
