Remove python 2.6 support and add python 3.7 test coverage

ngie-eign commented 5 years ago

About 2.6:

python 2.6 has been unsupported for at least 4 years. Drop support for the python version as there have been several changes made in recent years to fix functional and security bugs with the interpreter, etc.

It's best to upgrade to python 2.7 (if one is stuck on 2.x), or upgrade to py3.

About 3.7:

python 3.7.0 was released 10 months ago. As such, it's reasonable to add test coverage to ensure it functions.

It is reasonably close feature-wise to 3.6 that there will unlikely be any behavioral difference in this package. Some of the benefits of 3.7 over earlier versions is improved asyncio module support and general performance improvements.

More information about what's new in 3.7 can be found here.

About the Travis changes:

Switch from Trusty (the default Ubuntu distro) to Xenial in order to support python 3.7 testing with Travis, as Trusty lacks python 3.7 support.
Use pypy3.5 since the pypy package (unversioned) isn't available for Xenial, per the Travis CI docs.

About `dpkt.decorators`:

As part of this work, I realized that dpkt.decorators was unused. As such, reap all references to the module and the module itself.
