    l1sap: Pass is_sub from L1 primitive into the Uplink Measurement
    
    info_meas_ind on the L1SAP always allowed the lower layers to pass
    in whether a given measurement is part of the "SUB", or not.
    
    However, the existing l1sap code before this patch simply drops this
    information, despite the measurement.c code also having "is_sub" state.
    
    Let's make sure this state is passed from L1SAP into measurement
    processing as intended.
    
    Fact is, none of our current lower-layers actually set this is_sub flag
    for their primitives passed up in L1SAP, but at least now *if* they
    would set that flag, the measurement code would process it as intended.

    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.

    Revert "measurement: fix measurement computation"
    
    This reverts commit d5fdcfe6d95f52fb76c4f4201969347a062fc9fd, which
    introduces a new function lchan_meas_update_ordered_TA whose
    functionality I still haven't yet managed to fully understand. It
    appears to be adjusting the requested timing advance (lchan->rqd_ta) but
    outside osmo-bts-trx/loops.c code. This is odd, as rqd_ta is a state
    variable of that loops.c code.
    
    So for one part, it is a failure of encapsulation. The TA loop code
    should be self-contained, particularly as it is only used for
    omso-bts-trx, and not for the other BTS models. The new
    lchan_meas_update_ordered_TA() function is used from common code,
    applicable to all BTS models.
    
    The resulting interaction between loops.c code and this new (now
    reverted) function cause the TA value to only ever grow, despite the MS
    never moving at all.
