This is the layout expected by the "distro boot" effort in U-Boot.
As far as I understand, the contract is:
- U-Boot built for `fooboard` by `vendor`, will set the `fdtfile`
variable to `vendor/fooboard.dtb` - or more precisely: matching
whatever path the dtb is built at in the kernel tree.
- A distro (e.g. Infix) then just needs to specify the `fdtdir` in its
syslinux config (/boot in our case), and U-Boot will be able to find
the correct dtb.
Also renames all klix_SYM@klinfix to SYM@infix, this is fine since we're
always calling these symbols with @infix.

Turns out one of the reasons some keys did not work as they should in
certain commnands, most notably the Home/End in 'less', was due to the
default TERM variable being set to 'linux'. Changing to 'xterm' fixes
this issue, works with both console and ssh login, and from testing do
not seem to have any adverse effects on existing functionality.

This patch does two main things:
1) Breaks "statd" free from "confd".
2) Introduces netlink monitoring of interfaces for sysrepo data.
Prior to this patch, sysrepo operation status was handled by code
named "statd" inside "confd". (Where confd is a sysrepo-plugin and
not a real daemon, which its name implies)
In this patch, we break out the interface part of the operational
sysrepo status, previously "statd", into a new daemon, also called
"statd".
The main reason for doing this is to avoid sysrepo threading, which
allows the new "statd" to have control over sysrepo events in the
same event pool as netlink events from the kernel. This in turn allows
statd to subscribe and unsubscribe dynamically to interfaces that
comes and goes during runtime (such as vlans).
It also makes sense that "statd" is in fact a finit daemon.

To set up proper factory defaults in Infix we need to drop the default
/etc/sysrepo datastores, initialized at compile-time by Buildroot when
installing netopeer2. The pre-initialized datastores cannot be set up
with new {factory} data in any other way.
The system factory-config is constructed from two parts: static data and
generated data. The latter is:
- hostname (product name + the three last octets of the base MAC)
- interface defaults (depends on number of ports on the device) that
enable IPv6 link-local on all interfaces, and
- per-device unique SSH hostkey for remote NETCONF access, requires
openssl binary on target. Can maybe use openssh for this (TODO).
The hostkeys are saved in /cfg/factory.d/ to prevent them from being
regenerated on every boot.
The script gen-hostkeys and the update of 10-netconf-server.json are
inspired by the netopeer2 scripts merge_hostkey.sh and merge_config.sh,
which do just about the same thing for regular systems.
We bootstrap sysrepo early with all the required models, netopeer2 as
well as our own, by calling sysrepoctl with initial data for {factory}
and {startup} datastores. A local patch to sysrepo is used to allow it
to look for an /etc/factory-default.json instead of compile-time default
data, the patch allows us to have variable amount of objects in the init
data, e.g. number of interface objects.
A system startup-config is generated, if one is mising, from {running}.
We then drop the initial {running} datastore before starting the daemons
sysrepo-plugind and netopeer2-server so that they, and our plugins, are
ready when we load the system startup-config.
Some sanity checks and debug possibilities:
- Ensure /etc/sysrepo exists before copying factory-config
- Keep factory-default.json for debug

These packages are not (yet) used in the NETCONF build, only make sense
in the Classic Infix builds. SMCRoute will be needed later on, but not
right now, so also remove.
The dhcpcd package is only used by ifupdown-ng in Classic, in NETCONF we
use avahi-autoipd and udhcpc.
iproute2 is selected by the net tool, so collapsed by menuconfig.

Initial analysis of system default users gives that there is no real
need for a default 'factory' user to trigger a factory reset. On an
actual physical device we will have a reset button or a menu option in
the bootloader to trigger factory reset, and in both physical and
virtual (GNS3) devices a logged in admin user can call the factory
command.
A virtual device that cannot be logged in to will have to be removed and
have its persistent backing store deleted, but that is the only real
downside to removing this user. The idea is to set a kernel command
line flag from the bootloader, and that could also be done from, e.g.,
GNS3.

This means that:
- The full boot order is now respected, using the magic "fallback"
varible in GRUB. This means that if an entry fails to load, we move
on to the next one in the defined order.
- Netbooting is supported. In this mode, GRUB will acquire an IP
address using DHCP, after which it downloads an image using TFTP.
- If we run out of valid entries, we always make sure to reboot. This
ensures that, e.g., a temporary TFTP server outage does not cause an
Infix device to get stuck in GRUB.
At the moment, the image handling is excruciatingly inefficient when
netbooting, as the image is downloaded multiple times behind the
scenes. Ideally, downloads would be cached, but a quick investigation
indicates that an implementation of this would take more time than we
can spare at the moment. Therefore, we settle for the working, though
wasteful, implementation.
Things we really want later, but don't use right now:
- MRP
- MSTP
Neat to have in a networking product, but not used at all by us atm:
- ttyd
- tmux

Infix integration of klish and klish-plugin-sysrepo.
Initially we add:
More flexible management of running vs. startup: Instead of always
committing changes both to running and startup, commit only modifies
running. To persist changes to startup, the copy command is
introduced. This lets the user copy from factory/startup/running to
startup/running at any time.
Well-known verbs like abort, leave, end, etc.

Add support for firmware updates via RAUC on aarch64. The created RAUC
bundle (images/infix-$BR2_ARCH.pkg) is signed with the same key used
to sign the raw FIT image.
On amd64, we use grub instead of U-Boot, because yours truly can't
figure out how to handle ACPI handover to the kernel.
The resulting image is now called disk.img instead of the old mmc.img,
since we can use it over any interface (e.g. virtio or SCSI).
This is not the full environment used by U-Boot, just the bits needed
for U-Boot to know which slot to boot and for Infix to know how the
boot process went.
U-Boot will selectively import/export only these keys during boot,
which avoids a malicious user from altering the boot in a way that
might bypass signature validation.
- Drop unused com32 modules
- Fix duplicate prompt output (serial not needed)
- Reduce timeout before booting default to 0.5 sec
- UI or DEFAULT must be set, otherwise isolinux complains
so replace ONTIMEOUT with DEFAULT
- Increase user-walked-away timeout to 5 minutes
- Always show the prompt
