Here's yet another batch of fixes to make the tests more robust
against different environments.  With this lot, I'm now able to run
the pasta, passt, passt_in_ns and two_guests tests on my Fedora
system.  I'm still hitting problems with the perf tests.

This series (specifically 11/18) updates the demo to use socat instead
of openbsd netcat.  This is needed, or the change to socat in the
mbuto image would break the demo.  However, I'm hitting unrelated
problems trying to run the demos, so the switch to socat is, alas,
untested.

David Gibson (18):
  tests: Remove no longer needed /usr/bin/bash link
  tests: Let Fedora find dhclient-script in /usr/sbin
  tests: Add rudimentary debugging to dhclient-script
  tests: Add some extra dhclient support directories to mbuto.img
  tests: More robust parsing of resolv.conf for DHCP tests
  tests: Handle the case of a nameserver on host localhost
  tests: Correctly handle domain search list in dhclient-script
  tests: Fix detection of empty 'hout' responses in passt{,_in_ns} tests
  tests: Fix creation of test file in udp passt tests
  valgrind needs futex
  tests: Use socat instead of netcat
  tests: Remove unnecessary ^D in passt_in_ns teardown
  tests: Remove unnecessary truncation of temporary files in udp tests
  tests: Use dhclient --no-pid for namespaces in two_guests tests
  tests: Clean up better after iperf tests
  tests: No need to retrieve host ifname in ndp/pasta
  tests: Correct determination of host interface name in tests
  demo: Use git protocol downloads
