implement baseic uplink measurement processing + reporting * gather measurements from each PH-DATA.ind * check every TDMA frame about meas period expiration * compute averages after period expired * put MS DL MEAS REP into RSL MEAS RES messages, include UL meas bugs: * L3 INFO content seems to have some offset * is_sub is not set anywhere * measurement periods might have up/downlink offset

measurement: fix measurement computation Timing advance is currently not taken into account when computing the measurement results, this commit fixes that Change-Id: I2e0dfd13b53e8aa2822985f12bf2985e683ab553

measurement.c: Hand Frame Number into measurement computation This is currently only used for logging, but will be needed for proper RX{LEV,QUAL}-SUB reporting in upcoming patches. Related: OS#2978 Change-Id: I07fd06e8a379cab7c0c2eb111c3f5600037d3c9e

measurement: make lchan_meas_check_compute() available to l1sap.c lchan_meas_check_compute() is a static function measurement.c. In order to distribute the measurement result calculation events, we need to be able to call lchan_meas_check_compute() from l1sap.c Change-Id: Ideffe896613e0feda443bc13dac59dcdbbc605aa

int lchan_meas_check_compute(struct gsm_lchan *lchan, uint32_t fn);
cosmetic: unify measurement sample handling in one function In l1sap.c we call lchan_new_ul_meas() and lchan_meas_check_compute() directly in sequence. Lets unify thos two steps inside measurement.c so that we only need to call one function from l1sap.c. Change-Id: If48bc7442dfaab8c36b93949f741de6e836e792a Related: OS#2975

void lchan_meas_process_measurement(struct gsm_lchan *lchan, struct bts_ul_meas *ulm, uint32_t fn);
measurement: make sure state is reset on chan act. At the moment only lchan_meas_reset is reset on channel activation. All other states are not reset. This may lead to irretations in the first measurement interval if there are still leftover messages from a previous connection. Lets ensure everything is reset to zero by zeroing out the whole .meas struct in struct lchan. - Add a centralized function that does the reset - Call that function from rsl_tx_chan_act_ack() in rsl.c Change-Id: I880ae3030df6dcd60c32b7144c3430528429bdea Related: OS#2975 Related: OS#2987

void lchan_meas_reset(struct gsm_lchan *lchan);
measurement: add unit tests for is_meas_complete() We do not test is_meas_complete() individually yet, but it is an integral part of the measurement processings since this function decides where a measurement interval ends. - Add unit tests that test TCH/F, TCH/H, SDCCH/4 and STDCH/8 Change-Id: I8f89d9e7092cd65ba4d5c5649140692dcc20bdd6 Related: OS#2987

int is_meas_complete(struct gsm_lchan *lchan, uint32_t fn);
measurement: make sure measurement interval end is detected the measurement interval end is detected by using the measurement indication that is related to the SACCH block as a trigger to start the computation. If the measurement indication for the SACCH gets lost because the block could not be received then the processing is not executed. This may cause wrong results or when it happens condecutively an overflow of the measurement sample buffer. - Store the frame number of the last received measurement indication - Use the stored frame number to check if an interval was crossed when the next measurement indication is received. If we detect that we missed the interval, catch up by running the computation and start the next interval. Change-Id: I3a86cd8185cc6b94258373fe929f0c2f1cf27cfa Related: OS#2975
