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.

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

Fix a bug where systems with OSPF enabled on some, but not all,
interfaces would cause the OSPF iterator to fail when accessing
iface['area'], which was missing. This caused the ospf_status.py
tool to return {}, resulting in empty OSPF data in sysrepo.
Fixes#1169 Expected neighbors not shown in sysrepocfg
