stdlib: update packages for python 3.9
By utilizing the packages listed in
https://github.com/jackmaney/python-stdlib-list
for python 3.8 and 3.9, we were able to drop all stdlib packages that
existed solely in python 2 and add the missing stdlib python 3 packages
This reverts commit 90102acdbb23c09574d27df8bd1f568d34e0cfd3.
Now that we are ready to make a new release we can revert the revert and
hopefuly never have to solve a mess like this again to keep master
synchronized with the latest release
By reverting all commits done since release v0.4.10 we will have the
master branch synchronized with the latest release available in pipy.
All commits done since the latest release will be moved to another
branch called `next` where we will centralize development. Once we are ready
for a new release of pipreqs, the `next` branch will be merged back on to
master and a new release will be made.
This change will make development more organized and will avoid new
issues from users complaining about features only present in master not working
on their installation of pipreqs.
I would also like to thank @pedroteosousa for his help on reverting and
squashing all commits
Currently, flake8 is accessible via `make lint`, but it does not run
along side the rest of the test suite. This change adds flake8 checks to
the tox.ini file to enable linting as a routine part of running tests.
Additionally, drop the changes made in #100.
By using tox instead of the default Travis-CI Python environments, we
ensure that we have a single entrypoint to testing both locally and in
CI. This reduces redundant code and makes it clear when test
environments don't match up on different platforms.
[tox-travis](https://tox-travis.readthedocs.io/en/stable/) is introduced
here to automatically run tox jobs under the proper Travis-CI
environments. Additionally, the coveralls step is moved to a [build
stage](https://docs.travis-ci.com/user/build-stages) to run once after
all other Travis-CI tests complete.
