This update added new revisions after undoing existing revisions.  That is
to say, the old revision is not a strict subset of the new revision.  This
situation occurs when you --force push a change and generate a repository
containing something like this:

 * -- * -- B -- O -- O -- O (102ed77e45d3146bf9f0d293819df8c4fe6e37d7)
            \
             N -- N -- N (de0cd696cf5af9a42a79ca5bd6d639f9259b351f)

When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.

Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

    IuCS: implement msc_call_assignment() for IuCS
    
    Send IuCS RAB Activation upon MNCC_CALL_PROC_REQ.
    
    Implement function msc_call_assignment(): decide between sending A-iface BSSMAP
    Assignment Request or IuCS RAB Assignment Request.
    
    Implement iu_rab_act_cs() to send the IuCS RAB Assignment Request. The IP
    address and port of the MGCPGW sent in the RAB Assignment are still hardcoded.
    
    The A-interface extension is not implemented yet.
    
    Declare ranap_new_msg_rab_assign_voice() to avoid including
    ranap_msg_factory.h, which would require adding ASN1 CFLAGS to Makefile.am.
    
    The mgcpgw_client as well as some more osmo-iuh functions are now linked from
    libmsc, hence add some dummy stubs to libiudummy and db_test.c.

    libmgcp: add mgcpgw client API
    
    Add an API to send MGCP messages to an MGCP GW, from the perspective of
    an MSC instructing the GW to setup RTP streams.
    
    The mgcp_protocol.h is mostly for the MGCP GW itself, other implementations
    forward incoming MGCP messages. So a simpler approach for an MGCP GW client
    is useful.
    
    osmo-cscn is going to use this to route RTP streams (for 3G).

    the IuCS-interface will send a RAB Assignment Request.
    
    Add function msc_call_assignment() to decide between A-iface and IuCS
    assignment, to be implemented in subsequent commit.

    Add libiu function to send a CommonID message down a UE connection,
    iu_tx_common_id(); add also a corresponding stub to libiudummy for linking with
    tests.
    
    Add libmsc function msc_tx_common_id() to call the above. Add this mostly to
    clearly indicate in msc_ifaces.h that libmsc is calling out of the MSC; also
    to do conn->via_iface checking.
    
    Call msc_tx_common_id() after ciphering is established, in
    _gsm48_rx_mm_serv_req_sec_cb()'s GSM_SECURITY_SUCCEEDED case.

    LU counters: count completion and failure, not messages sent
    
    From a human admin viewpoint it doesn't make sense to count the messages sent:
    
    When we use TMSIs, we first send a LU Accept with a new TMSI, and then expect
    the MS to respond with a TMSI Realloc Complete message. When that fails to come
    through, the LU actually ends in failure, even though a LU Accept was sent.
    
    In 3G, if a UE sends an Iu Release during LU (e.g. user enables flight mode),
    we cancel the LU without sending any reply at all, so nothing would be counted.
    
    Instead, count Location Updating results, i.e. completion and failures.

    gsm0408_clear_request(): actually free the released conn
    
    By having conn->in_release == 1, calling msc_release_connection() has no
    effect and thus never frees the conn. So, after all pending requests have
    been discarded, also discard and free the unused connection.

    complete IuCS paging implementation
    
    Add paging timeout to struct gsm_subscriber. Previously, paging timeout was
    implemented only on BSC level, where each request has its own timeout value.
    The MSC will still send individual requests to BSC or RNC level, where they
    timeout individually. However, the MSC must also have an own timeout to be sure
    to discard stale pagings that the BSC or RNC never replied for.
    
    Add handle_paging_resp(), copying the few libmsc relevant parts of
    gsm48_handle_paging_resp().

    paging: actually verify subscriber authorization
    
    Before this, any paging response would be accepted by the CN, without
    checking the database whether the subscriber is in fact authorized.
    
    The probability that a subscriber would be able to take unauthorized action
    is slim, nevertheless checking authorization status with the database should
    happen before we accept a connection.

    paging: change subscr_paging_cb() into subscr_rx_paging_response()
    
    Remove one layer of callback indirection in paging. When a paging response
    arrives, we always want to first secure the connection, thus a fixed
    subscr_rx_paging_response() function is more appropriate and avoids having
    to store a cbfn. The actual actions to be taken upon successful paging are
    of course still in callback functions stored with each subscriber.
    
    Remove paging_request_stop() call from subscr_paging_dispatch(), which stops
    paging on all BTSs, which is not the responsibility of libmsc.

    cut off libbsc paging, pending paging in libmsc
    
    Temporarily disable all paging to be able to link libmsc without libbsc.
    Skip the paging part of channel_test because the paging is now disabled.
    
    In osmo-nitb, paging is done on BSC level and MSC level "at the same time".
    When the new CSCN is fully operational, paging will be controlled separately on
    the MSC level, and the BSC (RNC) level will be instructed over an IuCS or
    A-interface to negotiate paging with the MS (UE). This MSC level paging does
    not yet exist and will be added in subsequent commits.

    libmsc: duplicate gsm0808 / gsm48 functions (towards BSC)
    
    In osmo-nitb, libmsc would directly call the functions on the BSC level, not
    always via the bsc_api. When separating libmsc from libbsc, some functions are
    missing from the linkage.
    
    Hence duplicate these functions to libmsc, add an msc_ prefix for clarity, also
    add a _tx to gsm0808_cipher_mode():
    
    * add msc_gsm0808_tx_cipher_mode() (dummy/stub)
    * add msc_gsm48_tx_mm_serv_ack()
    * add msc_gsm48_tx_mm_serv_rej()
    
    Call these from libmsc instead of
    
    * gsm0808_cipher_mode()
    * gsm48_tx_mm_serv_ack()
    * gsm48_tx_mm_serv_rej()
    
    Also add a comment relatd to msc_gsm0808_tx_cipher_mode() in two places.

    Add msc_ifaces.[hc], a_iface.c, with a general msc_tx_dtap() to redirect to
    different interfaces depending on the actual subscriber connection.
    
    While iu_tx() is going to be functional fairly soon, the a_tx() is going to be
    just a dummy for some time (see comment).
    
    Add via_iface marker to gsm_subscriber_connection with enum values IFACE_A and
    IFACE_IU so far.
    
    Add Iu specific fields in a sub-struct: the UE connection pointer and an
    indicator for the Integrity Protection status on Iu (to be fully implemented in
    later commits).
    
    Add lac member to gsm_subscriber_connection, to allow decoupling from
    bts->location_area_code. The conn->lac will actually be set in iu.c in an
    upcoming commit ("add iucs.[hc]").

    split subscr_con_allocate()/_free() in bsc_ and msc_
    
    Rename current subscr_con_allocate() and subscr_con_free to bsc_*,
    and add two separate msc_subscr_con_allocate() and _free().
    The msc_subscr_con_free() ignores all lchan members.
    
    In libbsc use bsc_*, in libmsc use msc_*.
    
    Change-Id: I3cf7c7cafdf4672ec7b26058bba8a77159855257
    Future: there will be distinct subscr conns for libbsc and libmsc.

    Move timezone settings up to network level
    
    Time zone used to be configurable per-BTS. In the upcoming MSC-split, no BTS
    structures will be available on the MSC level. To simplify, drop the ability to
    manage several time zones in a core network and place the time zone config on
    the network VTY level, i.e. in gsm_network. If we are going to re-add fine
    grained time zone settings, it should probably be tied to the LAC.
    
    Adjust time zone VTY config code (to be moved to libxsc in subsequent commit).
    
    Adjust time zone Ctrl Interface code.

    reinvent connection_for_subscr() and move to libmsc
    
    Implement connection_for_subscr() from a completely different angle: instead of
    looking up lchans in bts structs, look up the subscriber in the global list of
    gsm_subscriber_connection. static lchan_find() is thus obsoleted.
    
    All callers of connection_for_subscr() live in libmsc, so move to libmsc.
    
    The move and edit are done in a single commit since the old and new
    implementation have nothing in common.
    
    Future: osmo-cscn will use this, without bts being present.
    
    Remove implementation of connection_for_subscr() from channel_test.c -- it is
    possible that the abort() in there was intended for a regression test, but
    actually it seems the implementation was merely added for linking reasons, and
    the abort() added to guard against the NULL return value: no comment nor the
    commit log indicate that the abort() is test critical; the addition was the
    only change in channel_test.c for that commit; at the same time a
    connection_for_subscr() call was added in libmsc.

    move to libxsc: network VTY that isn't BSC-specific
    
    Keep only BSC specific bits of the 'network' VTY node in bsc_vty.c, move more
    general VTY commands to xsc_vty.c.
    
    Add arg to xsc_vty_init() to pass a config_write_net() function. Pass a libbsc
    specific config_write_net() function.
    
    Future: upcoming omso-cscn will re-use the VTY bits moved to libxsc and pass a
    different config_write_net() function.

    sms_next_rp_msg_ref(): use direct pointer to next_rp_ref counter
    
    libbsc and libmsc will have separate subscriber connection structs. Hence don't
    rely on gsm_subscriber_connection, but work on a direct pointer to the counter
    for the next RP reference.
    
    The only very thin function in gsm_04_11_helper.c thus becomes obsolete: drop
    the entire file.

    move to libxsc: factor out gen of USSD notify and release complete -- TODO subscr_conn
    
    Both libmsc and libbsc need distinct gsm0480_send_ussdNotify() and
    gsm0480_send_releaseComplete() functions to account for the distinct subscriber
    connection structs.
    
    The current functions live in libmsc, so add the same in libbsc in new file
    gsm_04_80_utils.c.
    
    To avoid too much code dup, move the message generation part of
    gsm0480_send_ussdNotify() and gsm0480_send_releaseComplete() to new functions
    gsm0480_gen_ussdNotify() and gsm0480_gen_releaseComplete(), placed in libxsc.

    move to libxsc: net init 3: actual move
    
    Reincarnate gsm_network_init() as the parts not specific to libbsc.
    Move from bsc_network_init() those bits that are not BSC specific (and useful
    for upcoming osmo-cscn).
    
    Add libxsc to all linkages that use gsm_network_init().
    
    Note: the only requirement to allow linking gsm_network_init() without libbsc
    is to keep the call to gsm_net_update_ctype() out of libxsc. The other items
    are kept out of libxsc because it makes sense semantically. But the separation
    is not strong in that the BSC specific data members are of course still
    omnipresent in struct gsm_network. If bsc_network_init() is not called, these
    are not initialized properly -- for now no users of uninitialized members
    exist.
    
    So this is just a first step towards a sensible split of the BSC and MSC
    gsm_network structs. The long term aim should be to have entirely separate
    structs with some common general items.

    move to libxsc: net init 1: rename to bsc_network_init
    
    The gsm_network_init() function initializes a whole lot of BSC specific stuff.
    Aiming to move some of it to libxsc, first rename it to bsc_network_init().
    This will retain the BSC specific stuff when the move is done.
    
    Adjust all callers.
    
    Future: osmo-cscn will call the more generic part and not the BSC specific
    part.

    define mncc_recv_cb_t to avoid code dup
    
    Put mncc_recv_cb_t in xsc.h to avoid header include complications: if placing
    right above struct gsm_network, one must include gsm_data.h to use
    mncc_recv_cb_t as function parameter in a header, which will include
    gsm_data_shared.h, which will include xsc.h (future knowledge). Since I will
    need to use mncc_recv_cb_t in xsc.h, including gsm_data.h from there would
    introduce an #include loop. Avoid that and define mncc_recv_cb_t in xsc.h to
    begin with.
