commit 2d6a69e69a4b4cb2b8cc63c4810dae44e5a4d8f6
Author: Pau Espin Pedrol <pespin at sysmocom.de>

    Add support for IPv4v6 End User Addresses
    
    Before this commit, when an MS requested an ipv4v6 context osmo-ggsn
    returned an error stating the type was unknown, and this text was
    printed in the log:
    Processing create PDP context request for APN 'ims'
    Cannot decode EUA from MS/SGSN: f1 8d
    
    This patch has been tested with an MS running the 3 types of addresses:
    - IPv4 and IPv6: no regressions observed, the context is activated and
    packets are sent to the ggsn.
    - IPv4v6: Wireshark correctly parses request and reponse, and then
    ICMPv6 traffic from both sides. Finally I see the MS using the IPv4 and
    IPv6 DNS addresses advertised and TCP traffic over IPv4 (because
    probably my IPv6 network setup is not correct). I also checked I can
    disable/enable data (pdp ctx delete and activate) several times without
    any issue.
