To test the code under the influence of time jumps, add the option
(--timewarp) to the VM tests to reset the clock all the time, which
makes the wall clock time jump speed up 20x, causing gettimeofday()
to be unreliable for timeout calculations.

The vm-config in the subdirectory is less useful as it
will get removed by "git clean" and similar, so read a
config file from ~/.wpas-vm-config in addition.

Use a more robust design for collecting the gcov logs from the case
where test cases are run within a virtual machine. This generates a
writable-from-vm build tree for each component separately so that the
lcov and gcov can easily find the matching source code and data files.
In addition, prepare the reports automatically at the end of the
vm-run.sh --codecov execution.

Add a CHANNELS configuration to the script running the VM
that can be added to the vm-config file to allow running
the tests with hwsim devices supporting more than a single
channel.
Eventually, with the (hopefully) upcoming dynamic work in
mac80211_hwsim, this might go away entirely, but for now
this allows testing more code paths.

Rather than just having KERNELDIR, allow setting KERNEL directly.
Also remove the -s option that prevents running multiple machines
at the same time, but add a KVMARGS= variable that can be used to
restore that if needed.

Instead of running on the host, it can be useful to run in a
VM, particularly to test kernel rather than userspace changes,
so add a few scripts that allow doing so easily.
The basic idea is that the VM kernel is the same architecture
as the host kernel, so the host's root filesystem can be used
(in read-only mode) to run everything. Only a log filesystem
is mounted read-write and will get all the test output.
The kernel console output is collected to a special 'console'
file in the logs directory and kernel crashes are detected.
