This was missed when things were renamed.
The intention with this code was (apparently) to provide a (pseudo)unique
hostname in the case where something more specific was not provided (e.g. by
DHCP). Make this a little clearer by using '(none)' rather than 'linuxkit' as
the default, in the normal case this will be overwritten by something more
specific and if it isn't we will change it to something somewhat unique derived
from the MAC address (as before). nb: '(none)' is already used by Debian so I
think it is a safe choice as the sentinel value.
The use of both CONFIG_DEFAULT_HOSTNAME and the explicit /etc/hostname from
mkimage.sh is likely to be redundant in some cases, but neither seems to
completely cover all cases so keep both.

This is the default NIC provided by virt-install, I think it is also pretty
common on other virtualisation platforms since both the drivers and the
emulation are pretty widespread (IIRC Xen HVM guests used to get this by
default, and may still do).
Personally I'd probably try and remember to switch to virtio (or even e1000) in
preference, but that's one more thing to do.
Bump the image number.

... and accept the defaults. Doing so enables some hw monitoring on Intel
(which enables some I2C thing) and explicitly disables a few Mellanox options.

On some hv_sock workloads which quickly open/close many connections
occasionally, channel IDs would get re-used while still having work
pending. This can cause a kernel crash on a NULL pointer exception.
The three patches added to the 4.9.x and 4.10.x kernels fixes
these bugs. The patches are being prepared to be upstreamed, but for
now we cherry-picked them from the developers tree.

The 4.9.19/4.10.7 kernels include the fix for the VMBus
memory leak, so we don't need to carry these patches anymore.
The patches against 4.9.x/4.10.x now also all have added a
"Origin" line pointing to the git tree the patches were cherry
picked from.

This adds a timestamp to the start of the kernel command line. Like this (from
a random system I have lying around, line truncated by me):
[ 0.000000] tsc: Detected 2665.038 MHz processor
[ 0.000021] Calibrating delay loop (skipped), value calculated using tim...
[ 0.000023] pid_max: default: 32768 minimum: 301

[ 0.003782] ACPI: 2 ACPI AML tables successfully acquired and loaded
This would be handy in relation to #1403.

A given image is pushed to hub twice, once as
kernel:<kernel version>.<major version>.x and once as
kernel:<kernel version>.<major version>.<minor version>-<n>.
The latter is used to decide if a new kernel image is pushed to hub.
Most users should use the former to pick up the latest kernel.

Note, the last two 4.9 patches are no properly
cherry-picked from linux-next. We previously had

0012-Drivers-hv-Log-the... is new, but may further aid
