A container's command line, as reported by podman, may comtain environment
variables, which the current regexp (added in ed4fe58) does not support.
Extend the regexp to allow environment variables and add an operational,
config false, 'cmdline' leaf node to allow any characters to be reported
for the full command line in the operational output.

Add reliable avahi client reconnect via explicit free+recreate, reduced
log verbosity (single 10s warning instead of 3×2s loop). Also, binary
TXT record filtering (UTF-8 + XML validity), and finally add a SIGHUP
handler for on-demand reconnect.

The operator sees Infix through YANG models and should not need to know
which library implements a given feature. Rename the public-facing
parts of the avahi module to use the mdns vocabulary:
- Log strings: "avahi: ..." → "mdns: ..."
- Public API: avahi_ctx_init/exit → mdns_ctx_init/exit
- Main type: struct avahi_ctx → struct mdns_ctx
- statd field: statd.avahi → statd.mdns
Internal types (struct avahi_neighbor, avahi_service, …) and file names
(avahi.c, avahi.h) are kept as-is — developers debugging at the C level
benefit from knowing the underlying implementation.

When the mdns service is stop-started (e.g. after a config change),
statd's avahi client fires AVAHI_CLIENT_FAILURE momentarily. With
AVAHI_CLIENT_NO_FAIL the client reconnects automatically, but the
immediate ERROR log is misleading:
ERROR: avahi: client failure: Daemon connection failed
New behavior:
- On AVAHI_CLIENT_FAILURE: start a 2 s deferred timer (no immediate log)
- Timer fires up to 3 times (~6 s total); on the 3rd attempt, check if
mDNS is enabled in the running config via a temporary sysrepo session
- Log ERROR only if the daemon is still down AND mDNS is enabled
- On AVAHI_CLIENT_S_RUNNING: cancel the timer, reset the counter, and
log NOTE "mDNS daemon reconnected" if a failure had been seen
This silences the error entirely when the operator has disabled mDNS
(expected), and defers it by ~6 s for a brief restart (self-heals
before the timer fires).

Replace logging + logging.handlers with a lightweight syslog wrapper,
and argparse with manual argv parsing. On a sama7g54, this cuts yanger
startup from ~770ms to ~470ms by eliminating ~300ms of stdlib imports.
Also batch external command invocations:
- ietf_routing: two sysctl calls instead of two per interface
- ietf_hardware: one ls per hwmon device instead of six
- bridge: fetch mctl querier data once instead of once per VLAN

This patch adds a background gps monitor to statd because the gpspipe
program, normally used to interface with gpsd, slows down access to the
operational datastore with *seconds*.
This background monitor is not load bearing for how chrony accesses the
gps + nmea information from gpsd, this is handled separately in SHM.

RSSI is a vendor-specific relative index (0-255), while dBm is an
absolute power measurement. Since we report dBm values from iw,
rename the leaf to signal-strength for accuracy.
Also, spruce up the table a bit. Allow it to resize, let the SSID column
be flexible, and right-align column(s) with numbers.

When fdopen() succeeds, the FILE stream takes ownership of the file
descriptor. Calling fclose() automatically closes the underlying fd, so
the subsequent close(fd) calls were double-close bugs that could cause
undefined behavior.

Service descriptions or command arguments may contain special characters
that need to be escaped in JSON strings.
Example:
{
...
"command": "udhcpc -f -p /run/dhcp-client-wan.pid -t 3 -T 5 -A 30 -a1000 -S -R -o -O 1 -O 3 -O 6 -O 12 -O 15 -O 28 -O 42 -i wan -V "NanoPi R2S"",
...
}
Also, wrap add_services() in a try/except instead of testing for keys.

This patch adds support for flexible columns. When a column is marked
as flexible it means it can be stretched when printing the table to an
optional minimal table width. Multiple columns can be marked and when
this occurs the padding is applied equally to all columns.
Also, make sure to only add 2 char padding between columns, not always
at the end, or we will require larger terminal than necessary.

Add resource-limit and resource-usage containers to YANG model. Podman,
and later conmon, enforce CPU and memory limits in a delegated cgroupsv2
hierarchy managed by Finit.
Resource usage is queried from 'podman inspect', which has more nodes
than what is currently possible to limit.
Requires Finit 4.15, or later.

Replace manual f-string formatting with SimpleTable/Column classes.
This new "framework" handles ANSI colors and padding. Removing the
hassle of manually calculating padding. You simply specify the header
with max number of chars the data can be and if you want left/right
padding and the "framework" calculates the padding for you.
We use this new "framework" to pretty print the newly added services
statistics.
