[BSC] Move the BTS-type specific code from bcs_init.c to bts_*.c
bsc_init.c was a big mess even only for two supported BTS models,
so before adding more BTS types, this needs a cleanup.
All the BTS specific code from bsc_init.c has now moved into
bts_{siemens_bs11,ipaccess_nanobts}.c
This has required that input_event() and nm_state_event() get both
converted to proper libosmocore signals instead of referencing external
symbols.
