Vadim Yanitskiy f4674e3f7a power_control: fix swapped lower/upper RxQual threshold values 
According to 3GPP TS 45.008, section A.3.2.1:

  c) Comparison of RXQUAL_XX with L_RXQUAL_XX_P (XX = DL or UL):

     Increase XX_TXPWR if at least P3 averaged values out of N3
     averaged values are greater (worse quality) than L_RXQUAL_XX_P.

  d) Comparison of RXQUAL_XX with U_RXQUAL_XX_P (XX = DL or UL):

     Decrease XX_TXPWR if at least P4 averaged values out of N4
     averaged values are lower (better quality) than U_RXQUAL_XX_P.

Given that RxQual is a value in range 0 .. 7, where 0 is the best
and 7 is the worst: L_RXQUAL_XX_P must define the worst quality,
while U_RXQUAL_XX_P must define the best quality value.

About OsmoBSC
=============

OsmoBSC originated from the OpenBSC project, which started as a minimalistic
all-in-one implementation of the GSM Network. In 2017, OpenBSC had reached
maturity and diversity (including M3UA SIGTRAN and 3G support in the form of
IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one
approach to fully independent separate programs as in typical GSM networks.

OsmoBSC was one of the parts split off from the old openbsc.git. Before, it
worked as a standalone osmo-bsc binary as well as a combination of libbsc and
libmsc, i.e. the old OsmoNITB. Since the standalone OsmoMSC with a true A
interface (and IuCS for 3G support) is available, OsmoBSC exists only as a
separate standalone entity.

OsmoBSC exposes
- A over IP towards an MSC (e.g. OsmoMSC);
- Abis interfaces towards various kinds of BTS;
- The Osmocom typical telnet VTY and CTRL interfaces.
