Get-mac

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

Added
* Full support for Windows Subsystem for Linux (WSL). This is working for
all features, including default interface selection! The only edge case
is lookup of remote host IP addresses that are actually local interfaces
will not resolve to a MAC (which should be ff-ff-ff-ff-ff-ff).
Changed
* Require `argparse` if Python version is 2.6 or older
Dev
* Updated tox tests: added Jython and IronPython, removed 2.6

Added
* New methods for remote host MACs
* Windows: `arp`
* POSIX: `arpreq` package
* New methods for interface MACs
* Windows: `wmic nic`
* DEBUG levels: DEBUG value is now an integer, and increasing it will
increase the amount and verbosity of output. On the CLI, it can be
configured by increasing the amount of characters for the debug argument,
e.g. '-dd' for DEBUG level 2.
* Jython support (Note: on Windows Jython currently only works with interfaces)
* IronPython support

Changed
* **Significant** performance improvement for remote hosts. Previously,
the average for `get_mac_address(ip='10.0.0.100')` was 1.71 seconds.
Now, the average is `12.7 miliseconds`, with the special case of a unpopulated
arp table being only slightly higher. This was brought about by changes in
how the arp table is populated. The original method was to use the
host's `ping` command to send an ICMP packet to the host. This took time,
which heavily delayed the ability to actually get an address. The solution
is to instead simply send a empty UDP packet to a high port. The port
this packet is sent to can be configured using the module variable `getmac.PORT`.
* "Fixed" resolution of localhost/127.0.0.1 by hardcoding the response.
This should resolve a lot of problematic edge cases. I'm ok with this
for now since I don't know of a case when it isn't all zeroes.
* Greatly increased the reliability of getting host and interface MACs on Windows
* Improved debugging output
* Tightened up the size of `getmac.py`
* Various minor stability and performance improvements
* Add LICENSE to PyPI package

Removed
* Support for Python 3.2 and 3.3. The total downloads from PyPI with
those versions in August was ~53k and ~407K, respectfully. The majority
of those are likely from automated testing (e.g. TravisCI) and not
actual users. Therefore, I've decided to drop support to simplify
development, especially since before 3.4 the 3.x series was still
very much a "work in progress".

Dev
* Added automated tests for Windows using Appveyor
* Tox runner for tests
* Added github.io page
* Improved TravisCI testing
