Osmocom has maintained this program since about 7 years now, while
the original author / copyright holder has completely disappeared.
With the introduction of Osmocom-style CTRL and VTY interfaces,
the way how the program is used and configured has substantially
changed. In order to avoid confusion in terms of configuration file
format etc, let's rename it to OsmoGGSN.

We haven nobody maintaining this platform, let's remove it.
In fact, only Linux and FreeBSD are part of the jenkins build tests,
so even Apple/MacOS is up for disposal. However, as it's more
popular, let's keep the code.

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
Change-Id: I22c3bf32a98e5daf99d6eaeac8c9f95cc7574774
Extend the IP pool implementation to be able to manage both pools
of 32bit addresses (IPv4) as well as pools of 128bit addresses (IPv6)

The definition of the APN field format in GTPv1 is hidden in a chain
of documents.
3GPP TS 29.060 (the GTPv1-C specification) Section 7.7.30:
> The Access Point Name contains a logical name (see 3GPP TS 23.060 [4]).
> It is coded as in the value part defined in 3GPP TS 24.008
3GPP TS 24.008 Section 10.5.6.1:
> The value part is defined in 3GPP TS 23.003.
3GPP TS 23.003 Section 9.1:
> The APN consists of one or more labels. Each label is coded as a one
> octet length field followed by that number of octets coded as 8 bit
> ASCII characters
This converts a literal APN (e.g. Label1.Label2.Label3) to a structured
field (e.g. \006Label1\006Label2\006Label3)

After so many years of silence, we don't expect the original author to
return to the project. To make things a bit simpler for us, we convert
the coding style to what we are used to (Linux style).
The conversion was made using the 'Lindent' script which is part of the
Linux kernel.
According to 3GPP TS 29.060 recovery is optional, add command line option --norecovery to remove this field in sgsnemu

Routing Area Information is an optional Field described in 3GPP TS 29.060 7.7.3
it can be added with command line option rai, in the dot separated format MCC.MNC.LAC.RAC
example : --rai 208.10.65535.255

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.

This adds support for the followng new GTP Information Elements:
RAT_TYPE, USER_LOC, MS_TZ, IMEI_SV
Furthermore, it allows to specify those fields as sgsnemu command line
arguments.
Some files like in sgsnemu and ggsn directory where exactly the same.
They are now moved to the same directory for easier maintenance
