[L] Change in osmo-trx[master]: proxy: detect TSC of bursts relayed from TRXDv0/v1

Add burst_synch: detect the training/synch. sequence of a burst by comparing known positions within it against the GMSK and 8-PSK Normal Burst TSC sets (3GPP TS 45.002 tables 5.2.3a-d, 5.2.3f-g), Access Burst (table 5.2.7-3) and Synchronization Burst (table 5.2.5-3) sequences, mirroring fake_trx.py's TrainingSeqGMSK.pick(). burst_fwd.c calls this whenever the source BURST.req did not already carry real TSC info, filling in mod/tsc_set/tsc (and OSMO_TRXD_F_ACCESS_BURST for a detected Access Burst) before the burst is relayed onward.
