Sort the list of mount points by destination. This makes the list
deterministic for reproducible builds and also ensures that, e.g.,
the mount for /dev happens before the mount for /dev/pts.

Currently 'docker export' is used to convert a linuxkit entry
in the YAML file to a tar file of the root filesystem. This
process creates a number of files and directories which have
the timestamp of when the 'docker export' is run. Fix 'em up.

When creating files for the "intermediate" tar ball,
fix the ModTime. This reduces the difference between
LinuxKit images build from identical inputs.

Support plain gzip'ed files, as used on arm64, and bzImage with
embedded gzip'ed kernel, as used on x86.

Add the '-vmlinux' flag to build and pass it all
the way to the kernel filter.
Note, this commit only adds the flag but does not
yet perform the decompression. This will be added
with the next commit.

Stash the kernel image in a local buffer and
flush it out once done.
This is preparation work for supporting uncompressed
kernels in the next commit.

On Linux a key in `~/.docker/config.json` indicates if a credentials helper is
in use (and which), if one is then the method is identical to the Darwin case
so refactor to support that.

If the YAML does not specify a kernel, kernel commandline
or any containers, don't create empty files. Note, an
initrd file is still created if the kernel image contains
CPU ucode.
This only applies to kernel+initrd and tar-kernel-initrd
output formats.

Using filepath primitives instead of manipulating file paths manually takes care of platform specific formats.

Note: this patch introduces an incompatibility in the
`linuxkit run vbox` arguments.
It wasn't impossible to specify more than one network adapter
to the `linuxkit run vbox` command.
This patch allows to specify more than one `-networking` argument to specify
different network adapters.
For instance:
~~~sh
linuxkit run vbox -networking type=nat -networking type=hostonly,adapter=vboxnet0
~~~
will setup the VM with 2 NICs.
It is also possible to get rid of the `type` argument.

VirtualBox hardware (like physical hardware) has only a limited number
of IDE device on an IDE Controller.
Unfortunately when using an additional drive, it was given the port
value of 2, which doesn't exists in VirtualBox IDE controllers (as
only 0 and 1 are permitted).
This change makes use of the SATA Controller which can host much
more drives, to hook the additional drives.

While processing the content of a tar image, linuxkit's moby tool is
blindly reusing the original tar format.
Moreover it locates the files under a new prefix, so if the original
file was stored as USTAR in the original archive, the filename length
and new prefix could be greater than the USTAR name limit leading
to a fatal error.
The fix is to always enforce PAX format on all copied files from the
original image archive.

When building the build context, symlink need special
treatment as the link name needs to be added when
building the tar.FileInfoHeader. This code does that.
We may also need to add a special case for hard links
as the moby/moby package 'archive' does, but this
should for now

This is the final piece. If 'sources' are defined, tar up
the sources and rewrite them accordingly. Pass it as build
build context to 'docker'.
This allows building from something like this:
├── etc
│ ├── foo
└── foo
├── Dockerfile
├── build.yml
└── main.go
With 'build.yml':
image: foo
extra-sources:
- ../etc:etc

This commit adds the ability to add a build context to
docker for the package build. The build context is passed
on stdin to the docker process.
