Adds the AT-command-based GPS daemon for the Quectel EC25 modem (the
device has no u-blox chip and qcomgpsd's diag interface hangs on this
hardware). Trimmed from broken's version: dropped cloudlog calls and
the IsDaylight / ScreenDisplayMode auto-switching (those belong to the
display-modes feature, port later).
Used solely for system clock initialization, on-screen UI speed, and
per-segment dashcam GPS metadata.
Self-driving must NOT consume gpsLocation — feeding it to locationd's
kalman filter screws up the math. Patch locationd to skip GPS:
- locationd_thread() no longer subscribes to gpsLocation/gpsLocationExternal
- handle_msg's GPS branches commented (dead code without subscription)
- the "save LastGPSPosition once a minute when gpsOK" block commented
(dead because gpsOK is now permanently false)
Result: liveLocationKalman.gpsOK = false for all self-driving consumers
(controlsd, paramsd, torqued, frogpilot_planner). They already handle
that case. Other liveLocationKalman fields still publish from the
camera-odometry + IMU + calibration kalman state.
system/clearpilot/__init__.py added so system.clearpilot.gpsd is a
valid Python module.
