Ericsson RBS series BTSs do not have a built in PCU. Rather than having
the PCU on board the PCU is co-located to the BSC in those cases. Just
like the MGW the PCU would connect to the CCU (Channel Coding Unit) via
E1 line. The PCU is connected via an unix domain socket (pcu_sock) to
the BSC to receive RACH requests and to control Paging and TBF assignment.
This patch adds all the required functionality to run an Ercisson RBS in
GPRS/EGPRS mode. It supports 16k I.460 E1 subslots and full 64k E1
timeslots (recommended)

Older commit started using OSMO_IMSI_BUF_SIZE, only available in
libosmocore 1.1.0 onwards, but forgot to increase the values in
configure.ac.

The BTS constructor uses functions of libosmocore that could in turn
want to log something. This requires the logging to be initialized
before.
The only way to achieve this is to add an __attribute__((constructor))
function *before* the BTS constructor is being run.
This solution might not be elegant, but I guess it's the only way to
initialize a C library before calling C++ constructors of global static
instance of a class.
In case anyone comes up with a better / cleaner approach, we can always
change later.
This change requires libosmocore >= 0.10.1, as only that permits
multiple calls to osmo_init_logging() which may now occur.
