Here's get another batch of fixes and cleanups for passt/pasta tests.
Some of these are preliminary fixes before an upcoming series changing
to use more reliable (less tmux screen-scraping dependent) methods for
dispatching commands in various contexts.  Others are just
miscellaneous fixes.

David Gibson (10):
  test: Convert distro tests to use socat instead of nc/ncat
  test: Split cppcheck and clang-tidy tests into different files
  test: Remove unused *_XTERM variables
  test: Ignore video processing temporary files
  test: Split setup/teardown functions for build and distro tests
  test: Only select a single interface or gateway in tests
  test: Rename slightly misleading "valgrind" tests
  test: Use shutdown test for pasta
  test: Log debugging output from test script
  test: Kill qemu by pidfile rather than ^C
