rsl: ensure measurement reports are sent
osmo-bts currently does not generate a measurement report in case the
SACCH of the related traffic channel is lost. This is a problem because
the moment when reception gets bad measurmenet reporting is crucial to
carry out handover decisions effectively.
The presence of a SACCH block controls the conclusion of the measurement
interval and the sending of the RSL measurement report. The latter one
not only requires a measurmenet indication, it also requires a fully
intact SACCH block.
Lets use the NOPE / IDLE indications from V1 of the TRXD protocol to
ensure a SACCH block is always reported up to l1sap.c. In cases where
the SACCH is bad, trigger the sending of the RSL measurement report
manually without attaching the measurmenet data from the MS (which we do
not have in this case)
