commit 145e2532f48fa860e5ce58368d813b927a6aec44

    Merge branch 'zecke/features/no-tmsi'
    
    When two phones use the same TMSI and no A3A8 is possible
    we could end in a hard to detect issue. Assume that the IMSI
    will not clash and we have issues for foreign simcards.

commit 666e36aea9ddb9ffc6fd1c7620943449be345355
Author: Holger Hans Peter Freyther <holger at moiji-mobile.com>
Date:   Mon Jul 13 20:33:08 2015 +0200

    nitb: Add a mode to not use TMSI for normal operation
    
    In case foreign simcards are used we can not do authentication
    and ciphering. In case a TMSI is re-used too early and we do
    page using TMSI we can't know which of the two MS is responding
    to us. We could change the "secure channel" routine to ask for
    the IMSI and only then stop the paging.
    
    As we don't have ciphering there is not much use in using the
    TMSI. Add a mode "no assign-tmsi" that will not assign the TMSI
    during LU. Now CM Service Request and Paging Response  will
    work using the IMSI. There can't be a clash with that.

commit 5f8a0c5c7031c15beac4532fcde7450b9c0f84fe
Author: Holger Hans Peter Freyther <holger at moiji-mobile.com>
Date:   Mon Jul 13 14:28:29 2015 +0200

    nitb: Be less strict about the reject cause
    
    When we can't find the TMSI then the subscriber is not in our
    VLR. We have not consulted with the HLR and it is better to not
    use such a severe error code.
