Neels Hofmeyr 063868e1e6 handover_logic.c: always do inter-cell channel activation 
In commit [1], the channel activation kind was modified out-of-context to use
Immediate Assignment in case of intra-cell re-assignment. This so far hasn't
worked out in tests, so instead stay with the strategy to use
RSL_ACT_INTER_ASYNC also for re-assignment within the same cell. We may move to
RSL_ACT_INTRA_IMM_ASS in a separate patch after proper testing.

[1]: 5eaa4fb821,
     I2d91765c1f9719c64fd99426a872cecc724215db
     "HO: add indicators for inter-cell and async ho, use for chan act type",

Note that so far, no re-assignment within cells is triggered by the current
handover decision algorithm, so the effect will be really noticeable with
handover decision 2 that is coming up.

See feature OS#2949 which asks for implementing actual RR Assignment to
handover within a cell.

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.
