lantz f0c726a42f Use /usr/bin/env python for virtualenv (#1025) 
This helps with virtualenv although it can open
up another security hole if you end up using an
unexpected python interpreter.

Overall it seems to make sense to err on the side
of usability but it's good to be aware of security.

However, for the remaining utility scripts that require
python 2, we explicitly note this with #!/usr/bin/python2.

lantz dffddc338f Install python3 mn last in install-mininet-vm.sh (#1021) 
This means that 'mn' will run be default in python3.

For python2, run

    sudo python2 `which mn`

Also:

- change mn execution line to /usr/bin/python
  (install seems to change it to python2 or python3)

- don't install python-is-python3 package

Sometimes we got no output with python 3 on ubuntu 20
This simplifies setLogLevel slightly and should work
on python 2 and python 3.

lantz 77c473687e Wait for exit to avoid leftover dp0 (#1002) 
In certain cases, dp0 and its interfaces were not
being cleaned up, probably due to scratchnet.py being
killed before it terminated. This in turn caused the
natnet test to fail.

lantz b7c412073a CI matrix build + 20.04 fixes (#990) 
Ubuntu 20.04 fixes:
- fixes sshd test
- speeds up examples/{treeping64,tree1024}.py
- debugging hacks/output for testLinkChange
- removes cfs from examples/popen.py
- improves nat in nodelib (netplan fixes?)
- makes some tests executable
- waits for switches to connect in tests to
  avoid race conditions
-- adds mn -w option and wait CLI command
Changes:
- REMOVES default "-v" argument for Controller()
  and adds verbose(=False) option; avoiding logging
  makes it faster
- CHANGES waitConnected to wait for 5 seconds
  as documented; we may wish to implement an argument
  to -w to set this timeout
Issues?
- There may still be an issue with the ovs-netplan-clean
  service causing the boot to hang ;-(

Bob Lantz 5100a38fcd pmonitor() fixes 
pmonitor() is hard to get right, but this seems like
a reasonable improvement:

1. non-blocking I/O so we can drain buffer with impunity
2. drain buffer after poll
3. unregister fd on POLLHUP

Note we may have a unicode splitting problem since we're
decoding chunks of bytes, but that is a problem for another
day I think.

lantz 9e5280b4d1 Python 3 Compatibility (Merge pull request #817 from lantz/py3-compat) 
Changes for compatibility with Python 3.

The approach is to make as few changes as possible to maintain compatibility with both Python 2 and Python 3.

We use whatever python is installed, and also support a PYTHON environment variable for installing another version.

For simplicity, we provide mininet.util.pexpect which works out of the box with Python 3 utf-8 strings.

Thanks to @cuihantao for looking at this as well and also for changes to MiniEdit.
