DOwnload and verify the Intel microcode package and convert it
to a cpio archive which can be prepended to the initrd.
It also adds the license file to the kernel package.

The iucode_tool is used to convert the Intel CPU microcode
binaries into a cpio archive. There is no alpine package
for it, so compile it from source.
This is for x86_64 only and on other archs we create a empty
file.

This is similar to ae64ab6b82 from #2849 which
did the same for runtime.mkdir.
This makes it possible to specify both host (absolute) or container (relative)
paths.

and choose one at random to use.

This simply starts a web server serving the specified directory.
It's useful for PXE booting.

This currently just copies the kernel/initrd to a destination
and writes the iPXE script there as well. The scheme is flexible
enough to support scp or other means for pushing in the future.
The kernel/initrd are conditionally decompressed (default for arm64).

Using the userdat to pass the iPXE script precludes us from passing
actual userdata to the instance. Instead pass a URL to the iPXE script.
The script is expected to be a <base-url>/<name>-packet.ipxe.
When starting a server also serve the iPXE script from memory (not
the file system). The http server needed extending to differentiate
between the serving files and the iPXE script and ServeMux is used
to differentiate based on path.
A subsequent commit will provide an option to write the iPXE script
to disk.

prefix packet.net specific functions with 'packet' and make
non-packet specific functions, such as validateHTTPURL()
more generic so that they can easily be moved to 'utils.go'
should they be needed elsewhere.

This looks like there are a couple of minor fixes to the
recent KPTI changes but nothing major...
