Implement a new CLA pair (mqttcli/mqttclo) that uses an MQTT broker
for direct or store-and-forward bundle delivery.
this uses the Eclipse Paho MQTT C synchronous client (libpaho-mqtt3cs)
mqtt specifics:
- Persistent sessions (cleansession=0) for offline queuing
- Topic scheme: ion/bundles/<duct_suffix>
- Optional username/password auth (-u/-p flags)
- Optional TLS with server and mutual authentication (-t/-c/-C/-k/-K)
New files:
- bpv7/mqtt/mqttcla.h — shared constants, duct parser, config helpers
- bpv7/mqtt/mqttclo.c — output daemon (MQTT publisher)
- bpv7/mqtt/mqttcli.c — input daemon (MQTT subscriber)
- bpv7/doc/pod1/mqttcli.pod — man page
- bpv7/doc/pod1/mqttclo.pod — man page
Build system:
- configure.ac: --with-paho-mqtt option, prefers libpaho-mqtt3cs (TLS),
falls back to libpaho-mqtt3c with warning
- Makefile.am: conditional ENABLE_MQTT build rules
Tests (both marked .optional, require mosquitto broker):
- tests/loopback-mqtt — basic loopback send/receive
- tests/mqtt-store-forward — offline subscriber queuing and redelivery
