The LO-locked sensors on these devices were getting routed to the MPM
API call get_lo_lock_sensor(), which takes a 'which' argument (rx or
tx). However, UHD wants to pass a 'chan' argument (0 or 1). The way the
code was structured, it would always return 'False' (LO not locked) when
the argument was neither 'rx' or 'tx'.
The solution is to add get_rx_lo_lock_sensor() and
get_tx_lo_lock_sensor(), which generate the appropriate 'which'
argument, but discard the 'chan' argument (there is only one LO per Tx
and Rx, respectively).
In UHD 3, we had two sensors names for LO lock on these devices:
lo_lock, and lo_locked. The latter is the more standard, and is checked
in examples like rx_samples_to_file.
In UHD 4, the latter was removed without comment. This adds the sensor
back again and also updates the documentation accordingly.
- Turns the E310 into an MPM device (like N3xx, E320)
- Factor out common code between E320 and E310, maximize sharing between
the two devices
- Remove all pre-MPM E310 code that is no longer needed
- Modify MPM to remove all existing overlays before applying new ones
(this is necessary to enable idle image mode for E310)
