f124367afb tests: parallel-vm: allow running without curses
Allow running without curses, in which case the log is simply written to
stdout instead of a file. This is useful for automated (but parallel)
testing. Note that in most cases, you'd want to specify --debug, and so
I added a .rstrip() there on the lines to clean that up a bit.

c64b6f62cd tests: Use python selector in the parallel-vm.py main loop
This gets rid of the loop that was polling for things to do every 0.25
seconds and instead, reacts to any data from VMs as soon as it becomes
available. This avoids unnecessary operations when no new data is
available and avoids unnecessary waits when new data becomes available
more quickly.

179279eb34 tests: Move VM starting delay control into parallel-vm.py
This is more efficient since we can now start only the necessary number
of VMs instead of always forcing all VMs to start with one second delay.
This can also control the starting delay by keeping at most two VMs
starting at a time instead of using the hardcoded one second wait for
each consecutive VM.

9dc07a1d55 tests: Fix 'unexpected exit' detection in parallel-vm.py
Now that parallel-vm.py is actually stopping VMs as soon as they are not
needed for retries, it is not really an unexpected exit to see a VM exit
while test cases remain in the queue as long as at least that many VMs
remain running. Get rid of confusing 'unexpected exit' status from the
UI in such cases.

4aaddecdd8 tests: Handle test retries through the same queue
This removes the separate rerun step from the parallel-vm.py processing
and instead, simply requeues the failed test cases into the same queue
that is used for the initial run. This is simpler and more efficient
since reruns start as soon as any VM is ready for processing them
instead of having to wait for all VMs to complete the first round.
Furthermore, this allows VMs to be stopped sooner when no more test
cases remain and that is helpful especially with the time travel patches
that make the wait-for-next-test step in the VM use all available CPU.

e339511007 tests: Optionally start telnet server inside VMs
If telnetd is installed and --telnet <port> is passed on the
vm-run.sh command line, start a telnet server (directly connected
to bash, no login) inside the VM(s) to be able to look into them
when something is wrong. Use a user network in qemu with a single
host forward from the specified port for this, listening only on
'localhost'.

Please note that this provides unauthenticated access to the guest
system from anything that can open a TCP connection on the host system.
The guess system does have access to reading all files on the host that
the user account running kvm has access to (and even write access if the
default ROTAG ,readonly parameter is cleared). In other words, this
option should not be used on any multiuser systems where kvm is run
under user accounts that are not dedicated for testing purposes (i.e.,
do not have access to any files that should not be readable to
everyone).

This needs CONFIG_VIRTIO_NET=y in the guest kernel.

For parallel-vm.py, the --telnet argument specifies the base port
and each VM index (0, 1, ...) is added to it.

addition, add the --long argument if it was specified for the test run
to avoid skipping test cases in the re-run case.
