sgsnemu support for QoS as defined in 3GPP TS 24.008

this patch allows to tweak any bit of the QoS field of the Create PDP context generated by sgsnemu , aligned with 10.5.6.5 of 3GPP TS 24.008 V10.0.0 (2010-09)

QoS field can be extended to "lenght 12" with option --qose1, as seen in real life on UMTS networks.
extension to lenght 13, 15 and 17 can be done with option --qose2, --qose3, --qose4, never seen IRL but allows to test 3GPP compliance of GGSN.
