Unit data to an individual ID (>= 1000000) was copied to every OpenBridge
(VER > 1) even when the destination was just heard on a local system and the
SUB_MAP lookup already delivers it there. A D-APRS gateway's ARS/LRRP answers
(one per minute per radio) went out on every configured bridge, multiplying
traffic and causing remote masters that mis-classify those frames to create a
dynamic talkgroup named after the radio id.
Skip the OBP fan-out when the SUB_MAP entry for the destination is on a
non-OPENBRIDGE system and younger than UNIT_DATA_LOCAL_SUB_MAX_AGE (900s).
Subscribers learned via an OpenBridge, or stale entries, keep the current
behavior, so a radio that moved to another master stays reachable.
Rescued from #72 (opened and self-closed by pyopower without a merge),
adapted to the current file layout.
Use SUB_MAP's stored peer id for delivery (repeat, unit-data, and
pvt_call_received), add Talker Alias support for private calls, and
report the receiving hotspot to the monitor.
Normalize all Python sources to the standard ADN copyright block with
complete GPLv3 notice. Add legacy attribution on routing and dmr_utils
ports; drop SemVer wording from changelog and fix an unused test import.
Match legacy routerHBP so ARS/LRRP replies to private subscribers
use pvt_call when SUB_MAP idle check fails, without marking unit data
ingress as voice-busy on the source hotspot.
Replace internal bridge terminology with routing (RoutingUseCases, AclRouter,
routing_table export). SubscriptionStore remains runtime authority with O(1)
indexes for router and downlink filters. Fix STATIC TG parity on OPTIONS/RPTO,
parrot in-band edge cases, and remove per-packet routing_table export from the
hot path that caused high CPU under multi-hotspot OBP load.
