move to libcommon-cs: global vty gsm_network pointer
Move gsmnet_from_vty() and the bsc_gsmnet global to common_cs_vty.c.
Rename bsc_gsmnet to vty_global_gsm_network and make it static to common_cs_vty.c, to
clearly mark the global variable for VTY use only.
Introduce common_cs_vty_init() to set vty_global_gsm_network.
