Currently we try to ssh into the machine for 10 minutes
even if it crashed right away. Make qemu exit on kernel panic
and stop ssh'ing when qemu exits.
Handling bad kernels fast is actually important for bisection.
Update #501
Rather than writing the diagnosis to the kernel console, Diagnose can
now directly return the extra debugging info, which will be appended ot
the kernel console log.
* vm/qemu: Improve debug output.
When running in debug mode, the number of VMs is reduced to 1.
State this in the debug output.
* vm/qemu: Don't start debug output with a capital letter.
As requested by Dimitry.
* vm: Provide debug message when reduing number of VMs.
Apply this change to all affected platforms for consistency.
Suggested by Dmitry.
* Add myself to AUTHORS/CONTRIBUTORS files.
* vm: Fix compilation issues missed in earlier commit.
* vm: Use logging to write debug message.
We currently have this list in multiple places (somewhat diverged).
Specify this "overcommit" property in VM implementations.
In particular, we also want to allow overcommit for "vmm" type.
Update #712
When manager is stopped there are sometimes runaway qemu
processes still running. Set PDEATHSIG for all subprocesses.
We never need child processes outliving parents.
Do not fail a reboot if the reboot command returns an error. Reduces the
wait time per ssh commands to 30 seconds.

Add a new isolated VM for machines that you cannot easily manage. It
assumes the machine is only available through SSH and create a reverse
proxy to ensure the machine can connect back to syz-manager.
