gbproxy: Rename functions related to tlli_info

This patch replaces 'tlli' by 'tlli_info' within the following
function identifiers:
  - gbproxy_delete_tlli
  - gbproxy_delete_tllis
  - gbproxy_remove_stale_tllis
  - gbproxy_touch_tlli
  - gbproxy_unregister_tlli
  - gbproxy_remove_matching_tllis
  - gbproxy_find_tlli -> gbproxy_tlli_info_by_tlli
  - gbproxy_find_tlli_by_* -> gbproxy_tlli_info_by_*

These functions refer to the whole logical link info rather than to a
certain TLLI. So they are renamed to be named consistently with
gbproxy_attach_tlli_info and others.
