Port performance counters to Python 3.

/proc/<pid>/status is opened in binary mode, so we need to parse it using
bytes-like regexes.

TestPerformanceCounter.test_get_memory needs similar minor adjustments to
use bytes where appropriate.

There were various combinations of tabs and spaces which Python 3 now
complains about.

Update _scanner for Python 3 types.

PyDict, PyUnicode, PyLong all are different in 3.*, and have even changed a bit
during the 3.x lifetime. But these all pass the new test suite, and avoid
allocating a PyLong for every object that we know about.

Python 3 doesn't have the old FILE interface.

Now we just use raw write() to file descriptors. It may mean we aren't doing
buffered IO, which is a bit of a shame, but at least it works on both Python2
and Python3 and still allows us to take a memory dump with fewer allocations.

Remove _format_list and _set_default as they were no longer used.

Use six.string_types instead of basestring.

216. By John A Meinel on 2020-02-03

Use cleaner import statements, since cython does it in a nicer way.

215. By John A Meinel on 2020-02-03

Update tests to be clearer about bytes vs text.

This is to avoid confusion where Python2 str objects are bytes while Python3 str objects are Unicode.

Better Unicode handling on Python 3

Change version string.

Officially it should be '.dev0' not '.dev.0' according to the python versioning
documentation.

Skip old-style classes on python 3
