Hello laforge, Jenkins Builder, 

I'd like you to reexamine a change. Please visit

    https://gerrit.osmocom.org/c/osmo-bts/+/16141

to look at the new patch set (#2).

power_control.c: Don't use announced MS Power level as input for loop calculations

Use instead the received MS Power currently in use by the MS matching
the measured signal. This way there's no need to wait for the MS to
reach the announced MS power level or add checks in case the MS doesn't
support that specific power level. Furthermore, more fine grained
announced power level value can be obtained faster due to more input
iterations not being dropped while waiting.

osmo-bts-trx specific algo was not following this approach and using
announced MS power instead because it's wowrking at a lower level and
henche was not using the transmitted MS Power level value by the MS as
input for the calculation.

The "if (diff < 2 && diff > -2))" condition is dropped since equal
signal strength may still result in a different MS power level announced
(the one currently used by the MS during tx of last SACCH block).
