[L] Change in osmo-bsc[master]: ASCI: Add System Information 10 support

by jolly

jolly has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-bsc/+/34626?usp=email ) Change subject: ASCI: Add System Information 10 support ...................................................................... ASCI: Add System Information 10 support A timer is used to wait some seconds before sending SI 10 to all BTS. This ensures that all channels are established by the MSC, before sending a complete list of VGCS/VBS neighbor cells for a call. For each BTS, an SI 10 is gerated with all other neighbor BTS. The SI 10 will only define neighbor cells within the same BSC, because it does not know about neighbor cells within other BSCs.
