commit c964a2cfa1b08e5bbda5d721a7a0095d26b53791
Author: Stefan Sperling <ssperling at sysmocom.de>

    ensure unique CellIDs in HNB-GW
    
    If we receive a HNB-REGISTER-REQ with a cell ID which is already used
    by another registered NNB, log an error and send HNB-REGISTER-REJECT.
    
    Tested manually by running two 'hnb-test' programs concurrently (they
    need to listen on different telnet ports; this port is hard-coded so
    I compiled two different hnb-test binaries).
    Then I issued the 'hnbap hnb register' command on the telnet interface
    of each, and verified that the correct action is logged by osmo-hnbgw.
    Both hnb-test programs can connect, but only one of them can register
    at a time. Killing a registered 'hnb-test' program terminates its
    connection and allows the previously rejected one to register.
    
    The new rejection log message looks like this:
     hnbgw_hnbap.c:429 rejecting HNB-REGISTER-REQ with duplicate cell
     identity MCC=901,MNC=99,LAC=49406,RAC=66,SAC=43947,CID=182250155
     from (r=127.0.0.1:42828<->l=127.0.0.1:29169)
    
    This change depends on a new API in libosmo-netif, which is added in
    https://gerrit.osmocom.org/#/c/6844/
