[PATCH] Run background processes in varnishtest

I would like to add non-blocking process execution in varnishtest,
something different than the existing shell and err_shell commands.

I have found several use cases:
- testing varnish tools (there's a varnishncsa test)
- running unrelated programs (eg. redis for a redis vmod)
- attach strace to a pid (varnish or other process)

The second patch introduces a new macro for "-n" options, eg. ${v1_name}.

This was inspired by #1742.

Of course it's useless for all interactive executions, but you can
currently start a process, send signals, write to its stdin, and
stdout/err redirection to files... That's probably enough for many
use cases.

I haven't done much more (like -expect on the status code) because
it can easily be added afterwards if needed.

Best Regards,
