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 (09b034b67315a3305c1f3117e54270af49489015)
            \
             N -- N -- N (1d238f7a32f786345fe5db4e1fdce8570033a1d4)

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.

    Use libvlr in libmsc (large refactoring)

    Original libvlr code is by Harald Welte <laforge at gnumonks.org>,
    polished and tweaked by Neels Hofmeyr <nhofmeyr at sysmocom.de>.

    This is a long series of development collapsed in one patch. The original
    history may still be available as branch neels/vlr_orig.

    TODO: This commit may be split in several smaller changes before merging to
    master.

    SMS:

    The SQL based lookup of SMS for attached subscribers no longer works since the
    SQL database no longer has the subscriber data. Replace with a round-robin on
    the SMS recipient MSISDNs paired with a VLR subscriber RAM lookup whether the
    subscriber is currently attached.

    If there are many SMS for not-attached subscribers in the SMS database, this
    will become inefficient: a DB hit returns a pending SMS, the RAM lookup will
    reveal that the subscriber is not attached, after which the DB is hit for the
    next SMS. It would become more efficient e.g. by having an MSISDN based hash
    list for the VLR subscribers and by marking non-attached SMS recipients in the
    SMS database so that they can be excluded with the SQL query already.

    There is a sanity limit to do at most 100 db hits per attempt to find a pending
    SMS. So if there are more than 100 stored SMS waiting for their recipients to
    actually attach to the MSC, it may take more than one SMS queue trigger to
    deliver SMS for subscribers that are actually attached.

    This is not very beautiful, but is merely intended to carry us over to a time
    when we have a proper separate SMSC entity.

    Introduce gsm_subscriber_connection ref-counting in libmsc.

    gsup_client: allow passing a unit id to identify with HLR

    Before, each GSUP client would contact the HLR with an identical unit id, i.e.
    "SGSN-00-00-00-00-00-00", with the result that some messages were sucked off by
    the wrong client.

    Pass explicit unit name from each gsup client user, so that OsmoMSC is "MSC"
    and OsmoSGSN is "SGSN". Hence the HLR can properly route the messages.

    Todo: also set some values instead of the zeros.

    Unrelated cosmetic change while editing the arguments: gsup_client_create()'s
    definition's oap client config arg name mismatched the one used in the
    declaration. Use oapc_config in both.

    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.

    If a conn breaks/vanishes during LU, we cancel the LU without sending any reply
    at all, so the failed LU would not be counted.

    Instead, count Location Updating results, i.e. completion and failures.

    (With the new VLR developments, LU counters need to be triggered in completely
    different places, and this patch prepares for that by providing sensible
    counters.)
