Getmac

Changed
* Added support for Thomas Habets' version of `arping` in addition to the existing iputils one (contributed by Ville Skyttä (scop) in [52](https://github.com/GhostofGoes/getmac/pull/52) and [#54](https://github.com/GhostofGoes/getmac/pull/54))
* Added support for docker in network bridge mode (contributed by Tomasz Duda (tomaszduda23) in [57](https://github.com/GhostofGoes/getmac/pull/57))
* Add CHANGELOG URL to PyPI metadata (contributed by Ville Skyttä (scop) in [58](https://github.com/GhostofGoes/getmac/pull/58))
* Fixed code quality test suite errors (includes changes by Daniel Flanagan (FlantasticDan) in [67](https://github.com/GhostofGoes/getmac/pull/67))
* Improved Android support (contributed by emadmahdi in [71](https://github.com/GhostofGoes/getmac/pull/71))
* Minor code quality fixes (2 years of neglecting master branch)
* Add [Code of Conduct](https://github.com/GhostofGoes/getmac/blob/main/CODE_OF_CONDUCT.md) for project contributors
* Add [SECURITY.md](https://github.com/GhostofGoes/getmac/blob/main/SECURITY.md) for reporting security issues (e.g. vulnerabilities)
* Deprecate Python 3.4 and 3.5
* Issue deprecation message as a warning in addition to a log message

Changed
* Added warning about Python 2 compatibility being dropped in 1.0.0
* Officially support Python 3.8
* Documented a known issue with looking up IP of a local interface on Linux/WSL (See the "Known Issues" section in the README)
* Added remote host lookup using `arping` as last resort

Dev
* Standardized formatting on [Black](https://github.com/psf/black)
* Lint additions: `vulture`, several Flake8 plugins
* Pinned test dependencies (pytest 5 dropped Python 2 support)
* Various quality-of-life improvements for contributors/developers

Changed
* Fixed sockets being opened and not closed when `ip` or `ip6` were used,
which could lead to a `ResourceWarning` (GH-42)

Added
* OpenBSD support
* FreeBSD support
* Python logging is now used instead of `print` (logger: `getmac`)
* Include tests in the source distribution
* (CLI) Added aliases for `--no-network-requests`: `-N` and `--no-net`
* (CLI) New argument: `-v`/`--verbose`

Changed
* Errors are now logged instead of raising a `RuntimeWarning`
* Improved Ubuntu support
* Performance improvements

Development
* Significant increase in overall test coverage
* Fixed and migrated the sample tests to `pytest`
* Added tests for the CLI

Added
* Type annotations (PEP 484)

Removed
* Dropped support for Python 2.6
* Removed the usage of third-party packages (`netifaces`, `psutil`, `scapy`, and `arpreq`).
This should improve the performance of lookups of non-existent interfaces
or hosts, since this feature was punishing that path without providing much value.
If you want to use these packages directly, I have a guide on how to do so on a
[GitHub Gist](https://gist.github.com/GhostofGoes/0a8e82930e75afcefbd879a825ba4c26).

Changed
* Significantly improved the performance of the common cases on Linux
for interfaces and remote hosts
* Improved POSIX interface performance. Commands specific to OSX
will be run only on that platform, and vice-versa.
* Significantly improved the speed and accuracy of determining
the default interface on Linux
* Python 2 will install an executor named getmac2 and Python 3 an
executor named getmac so they do not conflict when both RPMs are
installed on the same system (Credit: hargoniX)
* The `warnings` module will only be imported if a error/warning
occurs (improve compatibility with some freezers, notably PyInstaller)
* Improved system platform detection
* Various other minor performance improvements

Development
* Added unit tests for the samples (Credit: Frizz925)
* Scripts for building RPMs in the /scripts directory (Credit: hargoniX)
* Improved code quality and health checks
* Include the CHANGELOG on the PyPI project page
* Using `pytest` for all tests now instead of `unittest`

Documentation
* Added instructions on how to build a Debian package (Credit: kofrezo)

Added
* Windows default interface detection if `network_request` is enabled (Credit: cyberhobbes)
* Docker container (Credit: Komish)

Changed
* Changed project name to `getmac`. This applies to the
command line tool, GitHub, and the documentation.
* Use proper Python 2-compatible print functions (Credit: martmists)

Removed
* Support for Python 2.5. It is not feasible to test, and potentially
breaks some useful language features, such as `__future__`
* Variables PORT and DEBUG from top-level package imports, since changing
them would have no actual effect on execution. Instead, use `getmac.getmac.DEBUG`.

Dev
* Added example videos demonstrating usage (Credit: fortunate-man)
* Added contribution guide
* Added documentation on ReadTheDocs
* Added a manpage
