We have been defaulting to using raw kernels and initrds for awhile
now. Lets not make the legacy version anymore. Anyone that needs one
should be able to make their own with the correct variables.

fedup is deprecated and abandoned. Let's save time and disk by not
building `upgrade.img` when nothing is going to use it anymore.
For the record, performing upgrades using an initramfs from the new
system turns out to be fragile and hard to support:
* dracut initramfs isn't generic enough to handle booting all systems
(e.g. missing vconsole.conf means you get keymaps wrong, so users
can't unlock encrypted disks)
* The ABI differences between the two versions of plymouth, systemd,
etc. requires nasty workarounds at best and causes nightmarish
systemd crashes at worst
This patch removes all the code that built and installed `upgrade.img`.
For backwards compatibility, the API retains the `doupgrade` keyword
argument, and the `--noupgrade` flag is still accepted.
I originally added --add-template to support doing something similar
to pungi, which injects content into the system to be used by default.
However, this causes the content to be part of the squashfs, which
means PXE installations have to download significantly more data that
they may not need (if they actually want to pull the tree data from
the network, which is not an unusual case).
What I actually need is to be able to modify *both* the runtime image
and the arch-specific content. For the runtime, I need to change
/usr/share/anaconda/interactive-defaults.ks to point to the new
content. (Although, potentially we could patch Anaconda itself to
auto-detect an ostree repository configured in disk image, similar to
what it does for yum repositories)
For the arch-specfic image, I want to drop my content into the ISO
root.
So this patch adds --add-arch-template and --add-arch-template-var
in order to do the latter, while preserving the --add-template
to affect the runtime image.
Further, the templates will automatically graft in a directory named
"iso-graft/" from the working directory (if it exists).
(I suggest that external templates create a subdirectory named
"content" to avoid clashes with any future lorax work)
Thus, this will be used by the Atomic Host lorax templates to inject
content/repo, but could be used by e.g. pungi to add content/rpms as
well.
I tried to avoid code deduplication by creating a new template for the
product.img bits and this, but that broke because the parent boot.iso
code needs access to the `${imggraft}` variable. I think a real fix
here would involve turning the product.img, content/, *and* boot.iso
into a new template.
Use the same stage2 location for all arches, put it in images with all
the other images. This only effects boot.iso, live images still use
LiveOS/squashfs.img because that's where dracut's 90dmsquashfs-live
module expects to find it.
For boot.iso anaconda-dracut handles finding stage2, looking at
images/install.img and LiveOS/squashfs.img
The list of ARM platforms was represented as a static list to be
installed in .treeinfo for Beaker support, but as ARM moves to use
the multiplatform kernel the platform specific kernel images will
no longer be needed. This process is beginning in F18 (3.7 kernel)
with HighBank being the first to use the baseline kernel. Due to
this change, there will be no 'highbank' platform images, but Beaker
tries to import all platforms listed in .treeinfo. To avoid errors,
we should dynamically create the list of ARM plaforms, including
only those that are actually provided.

For ARM systems that require U-Boot wrapped images,
perform mkimage to create one for 'upgrade.img'.
