Replace BusyBox udhcpc6 with OpenWrt's odhcp6c for improved DHCPv6
functionality and better integration with Router Advertisements (RA).
The primary motivation is support for a common ISP deployment scenario
where IPv6 addresses are assigned via SLAAC (from Router Advertisements)
and DHCPv6 is used in stateless/information-only mode to provide DNS
servers and other configuration options. This hybrid RA+DHCPv6 setup is
standard practice for many ISPs but was not supported by udhcpc6, which
treats RA and DHCPv6 as separate, non-integrated mechanisms.
Additional benefits of odhcp6c:
- Better IPv6 Prefix Delegation (IA-PD) support with proper handling
of delegated prefix lifetimes and renewal
- Native integration of RA-provided configuration (DNS servers, routes,
addresses) with DHCPv6-provided options
- Support for stateless DHCPv6 via information-only mode
To verify stateless DHCPv6 integration with SLAAC addresses - the ISP
scenario that motivated this migration, a new test case has been added.

This update got pretty messy, since libyang had some
breaking changes. And unfortunatly rousette, libyang-cpp
and sysrepo-cpp has not made any new release yet.
Dump operational datastore to timestamped JSON snapshots every 5 minutes
(in /var/lib/statd/). The operational.json symlink always points to the
latest snapshot.
Implement hierarchical retention policy that keeps the first snapshot of
each time period (hour/day/week/month/year), providing fine-grained recent
history while preventing unbounded disk usage.
This will allow us to plot / track how the system state evolves as
well as give us somewhat fine-grained info in the case of an event,
such as a crash.
Add unit test simulating months of snapshots to verify retention
behavior using a statd stub that only runs the retention code locally
(unit test)

Validate keys in gen_hostkey() before passing empty keys to shell scripts,
preventing:
Nov 04 2024 10:54:25 confd[2697]: SSH key (genkey) does not exist, generating...
Nov 04 2024 10:54:25 confd[2697]: writing RSA key
Nov 04 2024 10:54:26 confd[2697]: do_convert_from_pkcs8: /tmp/tmp.FH1Hr1 is not a recognised public key format
Also, fix base64 content formatting with proper 64-character line wrapping
using printf+fold instead of echo.
Use PKCS#1 RSA format for public keys as required by netopeer2-server, while
keeping PKCS#8 format for private keys. Use proper ssh-keygen format flag
(PKCS8) for correct conversion.

Neither the IPv6 autonconf container, nor the recently moved DHCP client
container have an 'enabled' flag.
Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
Please note, this change drops not only the global enabled flag, but also the
per-interface enabled flag, converting it to a presence container. The name
of the container is also shortened from dhcp-client -> dhcp. A pattern that
expected to be reused also for the DHCPv6 client.

Bridge ports should not have IP addresses configured. The IP address
should be configured on the bridge interface itself, not its member ports.
Add YANG must expression to enforce this rule at configuration time.

A valid DHCP server setup for a subnet is one of pool and/or at least one
static host entry/lease. If pool is enabled the pool must have a start
and an end address.
To allow setting up a DHCP server with no pool and at least one static host
entry/lease, we make the pool a presence container, otherwise the pool will
always be set and trigger the below inference.
When an interactive CLI/Web user enables the address pool we infer a default
range .100-.250, but only for /24, C-class networks. This is what most users
know and expect.
The YANG model now validates that:
- If an address pool is created, both start-address and end-address must be set
- Each subnet must have either a pool or at least one static host entry
- The pool container is now a presence container, so "no pool" fully deletes it
