The tests create temporary files and fifos in a number of places.
Some of them can interfere with later test runs, and are awkward to
clean up.  Consolidate them in a single per-run directory in /tmp
which gets cleaned up automatically.

This is based on the earlier userns cleanup series.

Chances since v1:
 * Fixed a number of straightforward bugs where things were missed
 * Also removed files we're no longer putting into the source tree
   from .gitignore
 * Added an extra patch moving the video processing files

David Gibson (32):
  test: Correctly match "background" with "wait" commands
  test: Context execution helpers
  test: Allow a tmux pane to watch commands executed in contexts
  test: Integration of old-style pane execution and new context
    execution
  test: Issue host commands via context for most tests
  test: Use new-style contexts for passt pane in the pasta and passt
    tests
  test: Add nsholder utility
  test: Extend context system to run commands in namespace for pasta
    tests
  test: Use context system for guest commands
  test: Use context system for two_guests tests

  Allow --userns when pasta spawns a command
  test: Group tests by context then protocol, rather than the reverse
  test: Remove unused variable FFMPEG_PID_FILE
  test: Actually run cleanup function
  test: Create common state directories for temporary files
  test: Move context temporary files to state dir
  test: Dont regnerate small test file in pasta/tcp
  test: Use paths in __STATEDIR__ instead of 'temp' and 'tempdir'
    directives
