This test creates a variety of v4 (and one v6) pool and performs
allocations until the pool is full, then frees a random number of
randomly distributed addresses, re-allocates them and again checks that
they're all available and finally once the pool is full allocations
fail.

"The data returned by getifaddrs() is dynamically allocated and should
be freed using freeifaddrs() when no longer needed"

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).

If the default APN has not been started, it is not eligible to be
used in starting of new PDP contexts.

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.

Tell the user about possible causes of failure to set the IPv6

If we receive a GTP-C CREATE PDP CONTEXT for an APN that we were

When there's an interim error (e.g. in resolving the link-local address
or setting up the tun device), apn_start() simply calls apn_stop()
on the not-yet-fully-started apn_ctx.
This only works if apn_stop() doesn't bail out early in case of
a not-started apn_ctx, so let's remove the related check at the
start of the function.

GTP sequence numbers on GTP-U are optional for G-PDU type messages (i.e.
user-ip messages). Let's allow the user to specify this behavior by
a new pdu_t.tx_gpdu_seq flag. The flag is enabled by default to stay
compatible with the prior behaviour.

This per-APN vty option determines if we are transmitting GTP sequence
numbers in downlink G-PDU messages. This behavior is optional as per
GTP spec. The default behavior is "true", like before this change.

I'm not quite sure how I ended up doing this, but for some strange
reason the code before this commit is sending the ICMPv6 Router
Advertisements from some weird non-standard source address. This is
a violation of RFC4861 which clearly states that the source address
of router advertisements "MUST be the link-local address assigned to the
interface from which this message is sent."

Adresses two "TODO Should be avoided" comments about an extra memcpy()

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 3a4c67b4bf we introduced the

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.
