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.

4.2.11 Quality of Service Subscribed Service
This encodes the subscribed QoS of a subscriber. It will be used by the
SGSN during the PDP Context activation. If the length of the QoS data
is 3 (three) octets it is assumed that these are octets 3-5 of the TS
3GPP TS 24.008 Quality of Service Octets. If it is more than three then
then it is assumed that the first octet is the Allocation/Retention
Priority and the reset are encoded as octets 3-N of 24.008.
