commit 4c8e8f990a24fc5ecb24c5c21c944d8ab4dc7c1e

    Merge branch 'zecke/features/gprs-gsup-fixes'
    
    When communicating with a GGSN that is not the OpenGGSN
    the PDP context activation does fail. This is because on
    the activation of the first PDP context we need to supply
    a MSISDN. Extend the protocol, parse the MSISDN and then
    send it to the GGSN. The second item is that we have only
    forwarded the requested QoS of the subscriber. In most
    cases this is 0x0, 0x0, ... which means one requests a
    rate 0 byte/sec which the GGSN will not allow. Make it
    possible to receive, store and use the subscribed QoS of
    the Subscriber.

    sgsn: Handle different levels of QoS
    
    If QoS is only three bytes it does not include the allocation/
    retention policy. Otherwise it does. Copy it depending on that.
    We should have a macro for the clamping to reduce code duplication.
    
    The insanity does come from the MAP data and this seems to be
    the easiest in terms of complexity. It is an array of bytes that
    is transported from MAPProxy to the SGSN and then simply forwarded.
    
    The case of more than three bytes is neither unit nor manually
    tested so far.

    sgsn: Store subscribed QoS and attempt to use it
    
    sgsn_create_pdp_ctx should use the subscribed QoS. When selecting
    the PDP context we inject the QoS to be used into the TLV structure
    and use it during the request. Assume a "qos-Subscribed" structure
    only with three bytes and prepend the Allocation/Retention policy
    to the request.

    sgsn: Copy the msisdn to the sgsn_data and use it in PDP activation
    
    The MSISDN should be present for "security" reasons in the first
    activation of a PDP context. Take the encoded MSISDN, store it for
    future use and then put it into the PDP activation request.
    
    The MM Context contains a field for a decoded MSISDN already. As
    we need to forward the data to the GGSN I want to avoid having to
    store TON and NPI in another place. Simply store the data in the
    encoded form.

    gsup: Extract the QoS field
    
    Add roundtrip test for the new QoS IE. It will be consumed in
    later commits.

    gsup: Extract the new MSISDN string
    
    Extract the new MSISDN IE from the GSUP message and verify that
    it is read/written to the message.

commit 02d8c472bdff0a085cbedd9d902f7ced29e5d712
Author: Holger Hans Peter Freyther <holger at moiji-mobile.com>

    gsup: Specify the QoS service for the PDP info
    
    QoS is a mess. In MAP there is qos-Subscribed which is then extended
    using ext-QoS-Subscribed, ext2-QoS-Subscribed, ext3-QoS-Subscribed
    and maybe even ext4-QoS-Subscribed by now. The MAP ASN1 files defined
    how these need to be "linearized". Instead of copying this I have
    decided to include the two semantics with/without the Allocation/Retention
    policy using the size of the data.

    gsup: Document passing MSISDN as part of the response
    
    When asking the GGSN to create/open a PDP context one needs
    to send a MSISDN. The MSISDN can only be provided through the
    GSUP interface.
