This commit adds optional support for conversion from hashbrown's [1]
HashMap [2] and HashSet [3] types. The HashMap and HashSet implementation
in std::collections is a copy from HashBrown, but Hashbrown still
provides some features over the std::collections version. Primarily this
is rayon support and also using a default hasher which is faster
(although not DOS resistent). The hashbrown versions provide a drop in
replacement over std::collections to get these features. To take
advantage of native type conversion in PyO3 this commit adds hashbrown
as an optional dependency and when the feature is enabled the traits for
going between python and hashbrown::HashMap and hashbrown::HashSet are
available. This is handy for users of hashbrown which have to inline
these conversions manually in functions that take dicts as args.

* Add (failing) tests for issue #1064
* Return NotImplemented when richcmp doesn't match the expected type.
* Fix tests that expect TypeError when richcmp returns NotImplemented.
- The python code 'class Other: pass; c2 {} Other()' was raising a NameError:
c2 not found
- eq and ne never raise a TypeError, so I split the those cases.
* Return NotImplemented for number-like binary operations.
* Add dummy impl PyNumberProtocol for the test struct.
* Rework tests of NotImplemented.
* Make py_ternary_num_func return NotImplemented when type mismatches.
* Return NotImplement for type mismatches in binary inplace operators.
* Reduce boilerplate with `extract_or_return_not_implemented!`
* Extract common definition 'Other' into a function.
* Test explicitly for NotImplemented in the __ipow__ test.
* Add entry in CHANGELOG for PR #1072.
* Add the section 'Emulating numeric types' to the guide.
* Ensure we're returning NotImplemented in tests.
* Simplify the tests: only test we return NotImplemented.
Our previous test were rather indirect: were relying that Python
behaves correctly when we return NotImplemented.
Now we only test that calling a pyclass dunder method returns NotImplemented
when the argument doesn't match the type signature. This is the expected
behavior.
* Remove reverse operators in tests of NotImplemented
The won't be used because of #844.
* Apply suggestions from code review

* Add a note about #844 below the list of reflected operations.

* Added Rust initialisation of Python-allocated bytes
* Added unsafe PyBytes::new_with_unit constructor

* Fixed doc test imports for PyBytes::new_with and PyBytes::new_with_uninit
* Fixed clippy error in PyBytes::new_with_uninit test
* Added PyByteArray::new_with and Removed PyBytes::new_with_uninit

Offsets for dict and weakref are calculated from the end of the
PyCell struct. When using the non-dummy ThreadChecker, the offsets
were invalid since the `ThreadCheckerImpl` is not zero-sized.
This prototype implements use of Py<BaseException> as the instance to
use for exception instances. These instances integrate reasonably well
with the Rust’s standard error mechanisms by implementing the `Display`
and `Error` traits. These error types can also be stored into e.g.
`failure::Fail`s or other error types as a cause of some greater error.
