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 (599ae47fc601fda0eb42b3d76a1849322348ad27)
             N -- N -- N (b3d283e1afc0b8c4a8b998d4db43586143d70406)

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.

    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.

    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()

    While iu_tx() is going to be functional on this branch, the a_tx() is so far
    just a dummy (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).

    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.

    bsc vty: rename show_net_cmd to bsc_show_net_cmd
    Future: there will be an MSC-land show-net-cmd, so rename to something with
    bsc in its name.

    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.

    move to libxsc: global vty gsm_network pointer
    Move gsmnet_from_vty() and the bsc_gsmnet global to xsc_vty.c.
    Rename bsc_gsmnet to vty_global_gsm_network and make it static to xsc_vty.c, to
    clearly mark the global variable for VTY use only.
    Introduce xsc_vty_init() to set vty_global_gsm_network.

    drop libmsc from some tests, drop duplicate libbsc linking
    Because of libxsc, tests/gsm0408,subscr,trau no longer need libmsc.

    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.

    Future: this will be used by libmsc's subscriber connection, for osmo-cscn.

    fix build: osmo-bsc_nat: change linking order
    Moving gsm48_create* to libxsc affected linking of osmo-bsc_nat, resulting
    in an undefined reference to gsm48_extract_mi().
    Fix the issue by placing libfilter.a left of libbsc.a.

    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
    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.
