Rudimentary support for setting login shell for new users. Currently
hard-coded from what's selected in the Buildroot config, if Bash is
available or not.

The writesf() API was hard coded to always open files in "r+" mode,
which fails if the file doesn't exist.
Add a mode option to writesf() and writedf().
Also, drop the default motd, we don't have one in NETCONF mode.

Bringing down the current generation is a step of its own, so it makes
sense to let finit clear out all old services before setting up the
new ones.
For example, with avahi-autoipd, without this step, we would run the
following sequence when disabling it on an interface:
initctl disable zeroconf@iface
ip link set dev iface down
ip link set dev iface up
initctl reload
But we really want to stop the zeroconf service before the down/up
cycle on the interface, since that is likely to disrupt the
daemon. With this additional step, the sequence becomes:
initctl disable zeroconf@iface
initctl reload
ip link set dev iface down
ip link set dev iface up
initctl reload
Which means that finit won't try to restart zeroconf if it dies during
the down/up cycle, since the service is already gone at that point.
Saving running to startup follows the same pattern as config update of
candidate to running, so we must employ the same hook mechanism here.

Refactor register_change() wrapper, for sr_module_change_subscribe(),
with an additional twist of setting up a commit DONE event catcher.
This creates a global event hook that ensures we call 'initctl reload'
after all module callbacks have completed, regardless of the xpath and
without having to have "shadow" subscriptions to all new modules being
added to confd.
Based on on ideas from https://github.com/sysrepo/sysrepo/issues/2188

finit is not ready to accept the messages anyway, so we end up waiting
for the 2s timeout (2 times). Since finit won't setup a utmp entry
until it leaves runlevel S, we use that as the sync point for when
finit is ready to receive reloads.
This patch introduces basic user authentication support via sysrepo.
Namely it adds:
* The ability to create or delete a UNIX user.
* The ability to set or delete a UNIX user password.
The password needs to be hashed and in a UNIX shadow format, such as
"$ALG$SALT$HASH". We want to avoid the handling of clear text
passwords as much as possible. In the meanwhile, passwords
can be generated in the infix shell using mkpasswd.
CLI Examples:
Add a user:
configure> set system authentication user foo
Delete a user:
configure> delete system authentication user foo
Set a user password:
configure> set system authentication user foo password ...

This is very ugly, what we really want is that the commit_done_hook()
runs when *all* DONE events have been processed in all models. The
side-effect of this hack is that the callback is run twice, both for
ietf-systm and ietf-interfaces if both are modified.

This patch adds a first Infix model to augment ietf-ip with a node,
similar to the IPv6 'autoconf' node, also for IPv4. For IPv6 the
autoconf feature comes built-in, for IPv4 it is defined in RFC3927.
The setting behaves the same as for IPv6, but in the case of IPv4 we
enable avahi-autoipd per interface to acquire the 169.254/16 address.
