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.

There's a bit of trickery with the ip_pool and it's "lengty=8" IPv6
prefix handling, let's make sure we don't accidentially call any
support functions with addresses of wrong length.

In IPv6 GPRS, we actually don't want to allocate an individual v6
address (like in IPv4), but we want to allocate a prefix. The
standard prefix lengh is 8 bytes, i.e. a /64 prefix. This patch
extends the pool to be able to work with such v6 prefixes.

This function is used to compare an IPv6 address against another,
using the smaller of the two prefix lengths.

This patch enables the use of IPv6 PDP contexts. The phone will
have to request an IPv6 End-user-Address, and the GGSN will have
to be configured for an IPv6 pool.
The outer transport-layer IP between SGSN and GGSN must still be
IPv4, it is not modified by this patch

Extend the IP pool implementation to be able to manage both pools
of 32bit addresses (IPv4) as well as pools of 128bit addresses (IPv6)
