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 (c11f61401664eb9bb8282445356f5ca851ac1265)
            \
             N -- N -- N (1789a16e884fa069bc2244791a4659c84efdffc8)

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.

    sgsn: Add sgsn_mm_ctx_cleanup_free for safe shutdown
    
    Currently the MM context cleanup code is distributed over several
    functions. sgsn_mm_ctx_free not only frees data structure but also
    eventually stops the timer and does the subscriber clean-up.
    mm_ctx_cleanup_free (gprs_gmm.c) cleans up the PDP contexts and
    unassign the TLLI.
    
    This commit moves the cleanup code from both functions into a new
    unifying function sgsn_mm_ctx_cleanup_free that cares about the
    clean-up of all related sub-systems.

    sgsn: Don't allow mmctx == NULL in sgsn_update_subscriber_data
    
    Currently, sgsn_update_subscriber_data can be called with mmctx ==
    NULL and will find and associate the right context (if present) based
    on the subscriber's IMSI. This will not happen in regular use
    any more, since sgsn_update_subscriber_data will only be called when
    subscribers are used (auth mode 'remote') and in this case
    gprs_subscr_get_or_create_by_mmctx will already be called by
    sgsn_auth_request. Therefore, MM context and subscriber are always
    associated except for some test cases and experimental VTY usage.
    The current implementation of sgsn_update_subscriber_data also causes
    additional complexity for the deletion on MM contexts to avoid a
    ipossible double-free MM contexts.
    
    This commit removes the MM context <-> subscriber association code
    from sgsn_update_subscriber_data. That function must always be called
    with mmctx != NULL, now. To avoid problems with VTY and test usage,
    the calling subscriber function now only call
    sgsn_update_subscriber_data when mmctx != NULL, since the purpose of
    that function is to update that state of an existing MM context after
    subscriber data has been changed.
