[M] Change in libosmo-sigtran[master]: Move sccp_address_book logic out of vty.c

pespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/libosmo-sigtran/+/40500?usp=email ) Change subject: Move sccp_address_book logic out of vty.c ...................................................................... Move sccp_address_book logic out of vty.c Move it tto a file containing data domain code. Move the struct definition to a header so it can be used in other files like ss7_vty.c. It will be used in more places in follow-up patches.
