  Log Message:
  -----------
  emulator: btvirt: check pkt lengths, don't get stuck on malformed

Don't try to parse packet before whole header is received.

If received data has unknown packet type, reset buffer so that we don't
get stuck.

  Log Message:
  -----------
  emulator: btdev: clear more state on Reset

On controller Reset command, initialize most fields in struct btdev to
zero, similarly to the state just after btdev_create().

This excludes some fields like command bitmasks, which hciemu may have
adjusted.

To make this easier, add struct_group() macro similar to what kernel
uses.

  -----------
  test-runner: use virtio-serial for implementing -u device forwarding

Using pci-serial to forward eg. btvirt sockets is unreliable, as qemu or
kernel seems to be sometimes dropping part of the sent data or insert
spurious \0 bytes, leading to sporadic errors like:

    kernel: Bluetooth: hci0: command 0x0c52 tx timeout
    kernel: Bluetooth: hci0: Opcode 0x0c52 failed: -110
    btvirt: packet error, unknown type: 0

This appears to occur most often when host system is under load, e.g.
due to multiple test-runners running at the same time.  The problem is
not specific to btvirt, but seems to be in the qemu serial device layer
vs. kernel interaction.

Change test-runner to use virtserialport to forward the btvirt
connection inside the VM, as virtio-serial doesn't appear to have these
problems.

  doc: enable CONFIG_VIRTIO_CONSOLE in tester config

Enable kernel option that allows using -device virtserialport in qemu.
This is easier to make work reliably than pci-serial channel.

Enable KVM guest and PTP options in tester kernel config.

This allows synchronizing tester VM guest with host clock, needed for
testers that want to compare timestamps outside the VM guest.
