The idea is to only implement the GTP-C plane and configure the right
link-local source address on the tun-device and let the regular (Linux)
kernel take care of sending router solicitations and
accepting/processing the related router advertisement. This avoids a
lot of complexity in sgsnemu.
For this to work, you must have /proc/sys/net/ipv6/conf/$tun/accept_ra
set to either 1 (works only if no IPv6 forwarding/routing configured on
your sgsnemu-running system) or 2 (works even if forwarding/routing is
configured).

This just adds the capability to sgsnemu to request a certain PDP
EUA type. It doesn't mean it actually handles anything beyond the
existing IPv4 yet.

gengetopt by default picks the program name from PACKAGE (autotools),
which is osmo-ggsn and is obviously wrong in case of sgsnemu.
After this patch, "sgsnemu --help" no longer shows "osmo-ggsn" but
"sgsnemu" at the top of the help text.

This will replace the manual additions to cmdline.[ch] with
auto-generated code from gengetopt. We need to fix-up the RAT Type in
sgsnemu.c as the manually-added code diverged from what gengetopt
generates.

In commit 3a4c67b4bf0067c4949a60bc750d01e0576c5e08 we introduced the
--norecovery command line option, but this was apparently done by
manually editing the C source code rather than adding it to the .ggo
and letting gengetopt do its magic. Let's fix this up.

It seems like modern gengetopt no longer supports 'unsigned int'
argument types, and we need to use 'int' instead. tested with 2.22.6

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

We can simply use 'struct iphdr' from netinet/ip.h to achieve
the same goal (and be portable).

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)

We are not using this option in any of our projects and it is breaking
make distclean. Remove the option for now.

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.

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.

They are now moved to the same directory for easier maintenance

All those will be re-generated by "autoreconf -i" anyway, so
there's no point in keeping them in the repository.
Also, the 'bootstrap' script is no longer working with recent
autotools versions anyway.
