This commit implements Infix mDNS TXT records, version 1, for available
services. Hard coded for the moment.

This commit includes a small prestudy, done over a period of two weeks,
to gather information about common txt records used by hosts. The most
well-documented is the Apple Printing Spec, which among other things
defines adminurl. A proposed version 1 of the Infix txt record spec is
included in the document. I'm recommending alternative 2:
"vv=1" "vendor=Qemu" "product=VM" "ty=x86-64" "vn=KernelKit" "on=Infix" "ov=v24.03.0"
Including this information would enable quickly scanning a network to
see if the latest version of the software has been deployed. Please
note, I've not included the U-Boot firmware version in this proposal,
but it could be included as "vs=2023.10-kkit3", or similar.

Converting to gunicorn, which is the recommended production server for
Flask apps, means app main() function is no longer called at startup, so
we have to factor out the mDNS CNAME functionality for infix.local and
network.local to a separate app.
We take this opportunity to collapse the structure, move non-class
methods to __init.py__, and rename the AvahiAlias class. A prototype
for replacing the overhead of mdns-alias with a C daemon is in its
early stages.

This change also requires another restructure for netbrowse itself, hence
the relocation of files in the tree.

- Advertises the build-time $hostname.local as a CNAME to the A and
AAAA records already advertised by Avahi
- Advertises a special network.local CNAME and provides a fastcgi
service on unix:/tmp/netbrowse.sock for browsing mDNS services
This commit also activates netbrowse by default with nginx listeing
to port 80 on IPv4 and IPv6 /browse by default but also / if called
with server name network.local.

With an increase in requests to confine users to the CLI, access using
SSH/SCP/SFTP to the configuration is becoming more and more important.
The admin role in Infix is mapped to the UNIX group 'wheel', meaning we
want all users in that group to be able to read and write files with
that ownership.
This patch fixes the initial ownership of startup-config, and /cfg, and
ensures the copy command in the CLI retain wheel group permissions.

Both L2 and L3 is supported.
With VLAN-filtering:
admin@infix-00-00-00:/config/interface/br0/> set bridge vlans vlan 1 multicast-filter 224.1.3.4 ports e0
Without VLAN-filtering:
admin@infix-00-00-00:/config/interface/br0/> set bridge multicast-filter 224.1.2.3 ports e0
- Rename mdb -> multicast-filters
- Add support for L2 multicast groups
- Change vlan, multicast and mulitcast-filters containers to presence
containers. This will result in that snooping will be disabled when
creating a bridge (or a vlan if vlan-filtered)
- Force the user to choose between VLANs and Multicast on top level bridge configuration
- Force L2 multicast to be state permanent
If an absolute path contains '../' we disallow it because what are you
doing, possible security violation.
Built-ins for running, startup, etc. remain as-is.

On any change to a container network interface we should schedule a
restart of the container to activate the changes. This code triggers
also at boot, when applying the whole startup-config, which initctl
handles by queuing any create/touch events for services.
This patch depends on the two previous commtis backporing fixes to
Finit's initctl tool and an upgrade of the k8s-logger.

In 4bfedf7a9 support for disabling IPv6/IPv4 link-local addresses was
added, which in turn caused this regression.
Regression in the v24.03 release cycle, not released -- low severity.

This change adds limited support for container capabilities. It allows
a more fine-grained control than priviliged mode does.

In a host interface setup, i.e., moving an interface from the host to a
container, often using VETH pairs, any route should only be set when an
IP address has been set. This because the CNI ipam plugin, which we
use, require routes be part of ipam, which in turn requires an address.
For details, see <https://www.cni.dev/plugins/current/ipam/static/>

All querier functionality for IGMP now handled by mcd, even if there are
no VLAN interfaces on top of the bridge. Also, mcd now handles unique
query interval per interface, or per VLAN, so we no longer need multiple
daemons running.

This patch adds support for small incremental changes to bridge ports.
Changes where the libyang diff does not include a bridge reference so
that it will have to be synthesized from the current configuration.
For example, forgetting to set a port's PVID in a VLAN filtering bridge
setup, changing a bridge port's multicast flooding properties, or any
other per-bridge-port setting after the fact.
Fixes#349.

Temporary fix to prevent odd log messages. The fix is to add RAW VLAN
support to mcd so it can run as a proxy querier even if there is no
upper VLAN interface or IP address.

This patch adds validation of bridge port VLAN memberships and IP
addressing for VLAN filtering bridges:
1. Ports must be a member of this bridge
2. Ports cannot be tagged and untagged member at the same time
3. A VLAN filtering bridge does not support IP addressing
A VLAN filtering bridge can only be a tagged member of a VLAN. Any IP
addressing needs to be done using an upper VLAN interface.
NOTE: while technically possible break up these long must expressions
into multiple must expressions per node (split at 'and'), it will
break libyang in interesting ways that in turn make the confd
inference functionality stop working. E.g., creating VETH pairs.

A bridge port in a VLAN filtering bridge should be possible to configure
as "tagged only", i.e., to not assign ingressing untagged frames a VLAN
and instead drop them.

This patch fixes a runtime error triggered by modifying an interface
currently used by a container. The CNI code must always return the
CNI status (reserved for container or not).
How to trigger:
- Create veth pair
- Make one end container-network and add to container
- Leave
- Return to configure and set an IP address on container interface
- Leave - BOOM

Simplify interface generation by collapsing eth_ and ethlike_ifaces to a
single list. Let gen_iface_json() determine interface type by querying
each interface. This allows us to create bridge setups also for qemu
use-cases.
