[ Impact ]

wminput is completey unusable as it will immediately crash with
undefined symbol error.

$ sudo wminput <any random mac address>
ImportError: /usr/lib/python3/dist-packages/cwiid.cpython-310-x86_64-linux-gnu.so: undefined symbol: PyVarObject_CallFunction

This is mostly because the code was not properly ported to Python-3.

[ Test Plan ]

1. install wminput
2. execute wminput with a mac address

If the package is not fixed, it will fail with undefined symbol error.

Ideally someone with the hardware should test.

[ Where problems could occur ]

There are changes in the code and there are chances of regression due to
this change. But wminput as of now is already unusable, so any
regression can not be worse than that.

[ Other Info ]

The patch, even though looks big is mostly changing all the PyVarObject to PyObject, and few other changes.
Initially I tried to pick only the changes for PyVarObject but that resulted in errors for PyInt_FromLong. After fixing that, errors from PyCObject_Check appeared. So, I thought its best to use all the fixes from the Debian patch.


[ Original Bug Description ]

When trying to invoke wminput I get the following:

james at thelio:~$ sudo wminput [redacted MAC address]
ImportError: /usr/lib/python3/dist-packages/cwiid.cpython-310-x86_64-linux-gnu.so: undefined symbol: PyVarObject_CallFunction

This is a duplicate of 1958466, but I could not run apport-collect
against it because it was not my bug. Since it's been orphaned for over
a year, I made this bug and ran apport-bug to file it. I'm happy to
provide any additional data.
