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, on x86_64 for 4.12.9 a new kernel option,
HARDLOCKUP_CHECK_TIMESTAMP was added which defaults to enabled. It enables
a low pass filter to compensate for perf based hard lockup detection.
Added this option to the x86_64 4.12.x kernel confog file.

Due to https://github.com/moby/moby/issues/34199 we can't supply
the FROM image via --build-arg and use DOCKER_CONTENT_TRUST=1 for build.
So we pull the image with DCT and then explicitly build it without.
This regression was introduced with 8b84baf2 ("kernel: Allow disabling content trust")

For some use cases, we may want to add additional kernel
configuration options (e.g. when adding AUFS). This commit
enables it by:
- renaming DEBUG to EXTRA
- append kernel_config${EXTRA} to the kernel config
- allowing passing in an EXTRA argument to the make file

specifying NOTRUST=1 on the make command line disables
content trust just like with packages.

- The x86_64 kernel config was derived from our 4.11 config
and then adjusted with the recent changes
- The arm64 kernel config was derived from the 4.9 config

The new Dockerfile.kconfig can be used, via the 'kconfig' make target
to build a 'linuxkit/kconfig' images. This images contains the patched
source and default kernel configs for all supported kernels.
It's useful to updating the kernel config files.
While at it, also update the alpine base.

The kernel build currently downloads the source tar ball every
time, which is a little tedious when experimenting with kernel
configs or when compiling the kernel multiple times.
This commit adds a new 'fetch' make target which downloads the
kernel sources into ./sources. Then in the Dockerfile we add
the directory and only download the source if it is not present.
The tarballs signature is till checked on each build.

Otherwise files which have an updated timestamp but no actual changes are
marked as changes because `git diff-index` only uses the `lstat` result and not
the actual file contents. Running `git update-index --refresh` updates the
cache.

The definition of `$(TAG)` differs from pkg/package.mk and is only the
HASH+DIRTY since the full tag is defined by the kernel macro and varies for
each kernel.
Also `show-tag` is `show-tags` here due to the multiple builds. Individual
`show-tag_FOO` rules are provided similar to the `build_FOO` rules.

- Combine 'sign' and 'push' targets like it is done for

- Append '-dirty' to the tag if the repository is dirty.
- Don't push to hub if the repository is dirty.

Extract the perf binary from the kernel package and create
a new perf package for each kernel. The perf package uses the
same tags as the kernel package and only contains the perf
binary under /usr/bin. The perf package can be added to the
init section or included as a stage in a multi-stage build
for other packages.

For local testinf it is useful to store packages under a different
organisation on the hub (or indeed to select a different registry).
This is enabled by making the ORG configurable when calling make.

This add a new version of the Hyper-V socket support based on
https://github.com/dcui/linux/commits/decui/hv_sock/next-20170504
Note, this changes the Linux side API to Hyper-V sockets as the
support is now based on the VMware/virtio socket implementation.
This means that the Address Family and the addressing changes.
Other patches from the 4.10 kernel are no longer needed as they
were already upstream.
The new Hyper-V socket code has not been tested, but the kernel
boots fine on HyperKit and Hyper-V.

Building debug kernels (with additional run time checks and debugging)
was broken a few commits back. This adds back support for building debug
kernels.
In addition, it builds and uploads debug kernels for selected kernel
series (4.9.x LTS and latest stable). The tag for these kernels has
a "_dbg" suffix.
Update documentation.
