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 (bc8913432688707bd31b0f01a0ff02e27a2c0351)
             N -- N -- N (c901eab76f16fa2e44708aaee234d001cf4ef61f)

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.

    gprs_gmm: Fix bit mask when determining update/attach type
    Bit 4 is reserved in 3GPP TS 04.08 so exclude it from the type.
    In 3GPP TS 24.008 it indicates if a follow-on request is pending by the
    MS, but only in Iu mode. According to the spec it is not required to
    react to that request with a follow-on proceed so this field can be
    ignored for now.
    See 3GPP TS 24.008 Ch. 4.4:
    "Unless it has specific permission from the network (follow-on proceed)
    the mobile station side should await the release of the RR connection
    used for a MM specific procedure before a new MM specific procedure or
    MM connection establishment is started."
    as well as Ch.
    "If the network wishes to prolong the RR connection to allow the mobile
    station to initiate MM connection establishment (for example if the
    mobile station has indicated in the LOCATION UPDATING REQUEST that it
    has a follow-on request pending) the network shall send "follow on
    proceed" in the LOCATION UPDATING ACCEPT and start timer T3255."

    gprs_gmm.c: Don't try to de-reference NULL mmctx
    There was a comment in the code that certain GMM messages require a
    valid mmctx pointer.  However, nothing actually checked if that pointer
    was in fact non-NULL.  We plainly crashed if a MS would send us the
    wrong message in the wrong state.
    Original patch by Harald Welte, but it broke message validity checking,
    resulting in sgsn_test failure. This re-implements the NULL check in a
    different way, as explained by in-code comment.

    subscr_name(): Handle case for subscr == NULL
    subscr_name() was called from several places:
    * either without a check for subscr being NULL, which for example
      was causing a segfault if we hand-over a channel before identifying the
    * or with an explicit NULL check and the ternary operator (?).
    We now simplify the code by checking for the NULL Subscriber in subscr_name()
