If the state dir is preserved then the VM should come up with the same mac
address on subsequent reboots.
Fixes regression in #2498.
Rather than fixing the typo in the associated comments just remove them since
they don't really convey any useful information.

This enables per task (IO) accounting which is useful
for monitoring IO activity and the like.

This PR is used to fix the issue #2488.
Currently we use '-net' the old way to initialize a host nic
interface, this method will not work on arm64 platform(#2488 issue),
so we use the '-netdev' method which will work on both arm64 and amd64.

This picks the correct GIC version to be emulated.
Without it you get an error on Thunder-X (and possibly others):
KVM_SET_DEVICE_ATTR failed: No such device

Newer 4.11.x kernels seem to trigger a bug (either in Linux or the
NVDIMM backend in Hyper-V) which causes silent failures of the
container VM.

Commit 5a3651b4a92c ("ext4: return to starting transaction in
ext4_dax_huge_fault()") introduced between 4.11.1 and 4.11.2
causes LCOW to stop working (VM silently exits). It is unclear
if this commit is the root cause or if it triggers something
in the Hyper-V backend or if it is unrelated.
But, in order make progress on other LCOW testing, we temporarily
use need to use this older kernel untile the issue has been
root caused.

This adds support for the updated Hyperkit API, which is needed to
request a specific IP address in new versions of VPNKit / Docker for
Mac. IPs encoded in the UUID (the old method) will now be ignored by
VPNKit.
A preferred IPv4 address can be requested directly via the new API. The
IP is then associated with the VPNKit UUID identifying the connection.
The UUID is either user specified or randomly assigned if left empty.
VMs launched with the same VPNKit UUID it will get the same IP address.
To avoid having to copy the assigned UUID manually, a file `uuid.vpnkit`
is now saved in the state directory when the UUID is generated. The UUID
from this file is reused automatically if it exists, unless a different
VPNKit UUID is specified on the command line. This also means that VMs
that use dynamically assigned IPs will by default get the same IP each
time they are started, as long as the state directory exists.
This change is incompatible with earlier versions of VPNKit / Hyperkit
and a recent version of Docker for Mac has to be installed. If the
feature is unsupported using the `--ip` parameter will exit with an
error message.

This adds building the zfs-kmod package to the kernel build.
The zfs-kmod packages contains the matching ZFS kernel modules
for a given kernel in /lib/modules/$(uname -r)/extra.
The zfs-kmod package also contains the standard kernel modules
and depmod is run over them so that modprobe works
The zfs-kmod package is not build by default due to unclarity
about licenses. Users will have to build it themselves.

Note this is not the latest ZFS version but the version matched
