[layer23] Adding application generated measurement report

The cell provides SYSTEM INFORMATION 5* and 6. These are used to create a
list of neighbor cells to monitor. Because there is no neighbor cell
monitoring supported by layer1, the list has no valid results yet.

Currently the average RX level of received frames are used to generate a new
report every second. The report is transmitted to layer1 and used there
whenever a measurement report has to be transmitted.

The timing advance and the current transmit power (as requested by network),
is included with every report.
