"parallel-vm.sh <number of VMs> [arguments..]" can now be used to run
multiple VMs in parallel to speed up full test cycle significantly. In
addition, the "--split srv/total" argument used in this design would
also make it possible to split this to multiple servers to speed up
testing.

This improves accuracy of the code coverage reports with hostapd-as-AS
and hlr_auc_gw getting analyzed separately.

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.

In order to handle regulatory domain requests, crda needs to be
installed on the host, but we also need to install a uevent helper in
the VM so that it gets executed (since we don't run udev).

If there's code coverage analysis data, copy it out of the VM
to be able to analyse it later. Also add a description to the
README file about how to use it.

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.

In some cases, e.g., with the VM tests if the VM crashes, it
can be useful to know which tests should have run but didn't
(or didn't finish). In order to catch these more easily, add
an option to prefill the database with all tests at the very
beginning of the testing (in a new NOTRUN state) and use the
option in the VM tests.

Create a results.db in the output directory when running
the tests in a VM. To make that easier, create the tables
in the python script if they don't exist.

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.
