commit 5ab622d2b72ac6df9d71d42736a6a65ac76cfab5
Author: Harald Welte <laforge at gnumonks.org>
Date:   Thu Feb 22 22:24:19 2018 +0100

    fake_trx/ctrl_if_(bb|bts).py: add FAKE_TOA command
    
    FAKE_TOA is an auxilary CTRL command, which may be used to update
    the ToA (Timing of Arrival) value of forwarded bursts at runtime.
    This is useful for testing the measurement processing
    code in OsmoBTS.
    
    The command is implemented for both BTS and BB CTRL interfaces
    in two absolute and relative forms:
    
      CMD FAKE_TOA <BASE> <THRESH>
      CMD FAKE_TOA <+-BASE_DELTA>
    
    The first form overwrites both ToA value and its treshold.
    The second one is relative, and applies a delta
    to the current ToA value.
    
    The command affects Downlink bursts if sent on BTS CTRL
    interface, and Uplink bursts if sent on the BB CTRL.

    fake_trx/fake_trx.py: add options to enable field randomization
    
    By default, both RSSI and ToA fields randomization is disabled.
    Let's add command line options, which allow one to enable it.

    fake_trx/burst_fwd.py: disable field randomization by default
    
    Both RSSI and ToA fields randomization is only required in some
    specific test / use cases, so let's disable it by default.

    fake_trx/burst_fwd.py: calculate both RSSI and ToA separately
    
    In order to be able to simulate and randomize both RSSI and ToA
    values for Uplink and Downlink separately, let's calculate them
    in separate methods of the BurstForwarder.

    fake_trx: handle SETTA (Timing Advance) indicated by MS
    
    Timing Advance value is a timing correction value, indicated by
    the network to MS, which is used to compensate UL signal delay.
    In other words, the network instructs a phone to transmit bursts
    N=TA symbol periods earlier than expected.
    
    Since we are in virtual environment, let's use TA value to
    calculate the ToA (Timing of Arrival) value for BTS.

    fake_trx/data_msg.py: implement ToA parsing support
    
    This change implements ToA (Timing of Arrival) parsing, which
    was missing in the DATAMSG_TRX2L1. Since we use integer math,
    a ToA value is represented in units of 1/256 symbol periods.

    fake_trx/data_msg.py: use integer math for ToA
    
    In order to avoid both float arithmetic as well as loosing any
    precision, let's use integer math fot ToA (Timing of Arrival),
    i.e. let's express ToA values in units of 1/256 symbol periods.
