gprs: Track IMSI/TLLI to control APN patching

This patch adds IMSI/TLLI connection tracking and uses it to control
APN patching based on the IMSI. TLLI entries can expire based on age
and/or by limiting the TLLI list size.

VTY config-gbproxy:
  no core-access-point-name                   disable APN patching
  core-access-point-name none                 remove APN if present
  core-access-point-name APN                  replace APN if present
  core-access-point-name none match-imsi RE   remove if IMSI matches
  core-access-point-name APN match-imsi RE    replace if IMSI matches
  tlli-list max-age SECONDS                   expire after SECONDS
  no tlli-list max-age                        don't expire by age
  tlli-list max-length N                      keep N entries only
  no tlli-list max-length                     don't limit list length

RE is an extended regular expression, e.g. ^12345|^23456
