When sysrepo-plugind is processing callback events, make sure to log the
error and exit(1) the entire process so the system can handle the problem.
For example, restart all dependent services.

As of KernelKit Klish @ 710a631 the script plugin has been refactored to
run all commands as the logged in user instead of as root. The default
admin user is member of the wheel group, which allows access to sysrepo
and sudo access to containers thanks to NOPASSWD rights.
The doas script is a dummy wrapper to silence 'sudo -n' output for users
without any privileges.
As of this commit, unprivileged users can no longer copy, show, or in
any other way manipulate the system configuraiton.

This is a refactor to ensure sysrepo functionality guarded by NACM works
as intended in Infix.
Relocate infix_rpc() to klish-plugin-sysrepo, ensuring unauthenticated
users are denied access.
Drop infix_commit() in favor of slightly modified srp_commit(), this to
ensure sysrepo audit trail logs are visible at all times.

This commit introduces a new SECURITY() log macro that logs to facility
'audit' (sometimes called 'security') with severity set to 'alert'. It
is then used to instrument the single most important things to log; all
changes to users and their privileges.
We also add logging to sysrepo, which knows the username for changes to
running-config, copies to startup-config, and RPCs.

- For consistency and clarity, rename format -> log-format
- Add must expression to ban 'bsd' format from file logging
Note: technically, sysklogd silently reverts back to rfc3164 for file
logging, but it's better to be clear with the user with what is
possible to configure and is going to be used.

As a bare minimum, all augments and deviations made to standard models
should have a description denoting *why* they exist.
In the case of ietf-syslog the base model is still a draft and carries
some odd defaults we want to disable, or replace with better ones. The
augments are global log rotation and and log format.

This refactor changes the callback subscription for log-file and remote
log actions to ensure they are called for *all* changes. Even changes
to deeply nested sub-trees like file-rotation when no other changes are
made. The previous attempt failed to address that.
The refactored callbacks replace sr_get_changes() with srx_get_changes()
for better control over what they iterate over. The callbacks always
regenerate the syslogd *.conf file snippets for each log action, so
there is no need for the overly granular sr_get_changes(), ever.

Reduces the overhead/repetition for module callbacks by combining the
forces of srx_get_diff() and lydx_get_descendant() into one API. The
resulting function supports both XPath and simplified paths to get the
subtree of changes applicable to the callback.

This augments ietf-syslog.yang with global file rotation settings which
are used when per-file rotation is not configured. The defaults chosen
match previously decided defaults for Infix: 1M:10, i.e., rotate every
file at 1 MiB and keep up to 10 gzipped aged-out archives.
The standard model includes a default value of 1 for the number of files
kept, which is removed (deviated). There is also a unit specified for
max-file-size, 'megabytes', replaced with 'kilobytes' in this change.
On smaller embedded systems, smaller sizes may be required.

When a the type of a leaf node (of a list) is buried inside a union we
need to fish out the module prefix if one of the types in the union is
an identityref. It's all very simple really.
Also, when tab completing for possible identities, always make sure to
strip any leading module prefix.

These changes are designed to make the experience working with log files
easier. Both listing available log files and viewing them.
- replace C dir@infix with a shell script for easier extensions,
e.g., we want to show both available .cfg and log files
- add support for gunzipping .gz log files before viewing them

To support testing, the test-config.cfg file has been introduced in Infix.
Additionally, a "test mode" for the running image is required for this
configuration to be applied.
Basically the test-config will only be loaded when the device is in test mode,
which is determined by the presence of the /mnt/aux/test-mode file.
However, placing this file via the Qeneth system proved to be
inconvenient in the test environment. Therefore, it the entire image is
built in test mode, with the 'test-mode' file preloaded onto the disk
image (specifically in the auxiliary partition).
To support this, a new variable, (bool) DISK_IMAGE_TEST_MODE, has been
introduced:
enabled: the image will be built in the test mode;
disabled: the image will be built in the standard mode.
Part of issue #568
Currently, it's not possible to run infix tests from an external
project (based on infix) due to an incompatibility between the
configuration used in the tests (the default configuration
within the image generated by the external project) and the infix
base configuration expected by the test cases. Therefore, a simple
configuration specifically for testing purposes needs to be generated
within an image. This test-config should always be generated
but only loaded when the device is in test mode.
Part of issue #568
If a container has not yet stopped/started we may for proto RESTCONF get
"invalid URI" result back for some container actions. With this change
we allow the action to be retried up to three times before passing on
the error.
In tests on Qemu (x86_64) this happens very rarely and need at most one
retry before succeeding. Verified by iterating the same basic test over
night (9000+ iterations).

These changes are intended to make yanger a bit more robust. Instead of
bailing out on command errors, we now return empty string or object back
to the callee in run_cmd() and run_json_cmd().
One example where yanger previously exited hard, and dragged with it the
entire session, is when inspecting container status or when attempting
to restart container instances which have yet to be created/stopped.
