RC calibration and mapping debug

Add "skip" buttons in msg box (instead of cancel); allow user to cancel
upload of rc params after reviewing them

Add persistRcValuesButt to allow mappings to be persisted outside the
calibration mode; cleanup const params in param dataq model;  add some
debug for mapping problems

Cleanup pending items tree completely when we receive an update
