some updates for release process, docs, testing (#26)

ThomasWaldmann · web-flow · commit afb3fd1da899 · 2020-10-04T14:52:52.000+01:00
* setup.cfg: use default format for sdist (.tar.gz), see #25 * we need a very recent cython to support python 3.9 there were some incompatible changes in python 3.9, thus code generated by old cython versions won't compile. * fix typo in changelog it still worked for py38, but py39 was broken because they removed some deprecated stuff still present in the old cython-generated C code. * travis: testing on all python versions also: on differently old linux dists * pypi metadata: be more precise about python versions Note: I used the same python versions as for borgbackup because I run extensive release testing for these versions (which indirectly tests llfuse also) plus python 3.9 which should also work after fixing llfuse's cythonized code for it. There might be a need to drop 3.4 and 3.5 later again because they are EOL, but for right now, they're still working and tested. * disable developer mode on travis-ci
