Nemu previously had an issue with PIDs above 4 hex digits (> 65535) where created network interfaces would have names of length exceeding IFNAMSIZ. These fixes have been upstreamed in nemu3.
Problems around the @ notation used by iproute have also been fixed and/or upstreamed in nemu3.

This reverts cfb2c159, 06f33ff2 and 27a27263.

Same as demo, tests expect a clean work directory, otherwise weird behavior will occur.

Python3 added automatic detection of leaked resources, which causes lots of warnings in Re6st, mostly because of unclosed subprocess streams.

In the end, we should migrate completely to cryptography. A lot of bits of the legacy OpenSSL module are being deprecated, some that we use (notably signature and verification tools) already are.

The demo expects its storage directory to be clean at start, otherwise undefined behavior will occur.

style: stop using deprecated getargspec for rpc

python3: migrate setup.py

style: remove new-style class code from the Python2 days

demo: properly escape screen command parameters

bug: fix wrong sending of HMAC header causing test failure

setup: indicate minimum Python versions

doc: update dependencies in readme

Fix permission for ovpn-client and ovpn-server

vcs: add test-related generated files to gitignore

No need for more logging since the culprit is visible everywhere
in routing tables.

This fixes default packet redirection when merging multiple re6st
networks. Nodes will then install multiple default routes for each re6st
network with the correspond src-prefix.

The changes include:

- redistribute default route with src prefix on gateways
- remove the now obsolete default option
- if subtrees is not available in the kernel, delete src prefix from
  the default route and don't advertise the default route to other
  nodes
- if there is no src prefix in the redistributed default route, add
  one to be retro-compatible with the old gateway behaviour

Implement select in multicast.py to fix immediate return causing 100% cpu load

This reverts commit f9b112a7

python-unshare and python-passfd are dependencies of nemu: https://github.com/NightTsarina/nemu/blob/master/setup.py#L18,
but nemu in pypi: https://pypi.org/project/nemu/0.3.1/ is outdated, it has no dependency defined
so keep those here

This is required for 47f69a00
("redistribute default routes with src-prefix").

See merge request !38

For instance 89.30.119.100 has an entry in the geoip2 database without country
key

anyway, let test failed if any error

modify fixnemu device name comment, remove extra line, space, remove dup
definition, eek

Remove duplicate definitions of DEMO_DIR, and define it in the tests
module
