This also makes sure it doesn't compile against older libosmogsm gsup
versions which would break ABI.

This option should be used for any executables which are used only
for testing, or for generating other files and are consequently never
installed. By specifying this option, we are telling Libtool that
the executable it links will only ever be executed from where it is
built in the build tree. Libtool is usually able to considerably
speed up the link process for such executables.

Some level of split already existed, like sgsn_auth.c, but headers were
entangled together.
Let's clearly separate application centric code (sgsn.c/h), auth related
code (auth.c/h) and mmctx related code (mmctx.c/h).
Change-Id: I048a082851c1275c959649942904205b02acce2a
This further shrinks the mess in gprs_sgsn.h, and allows to easily see
layer violations (like pdpctx.c requiring llc.h)
Change-Id: Iad4da06efee7d8514ff48423bdaebc0f26413cc1
The functions driving its lifcyecles are already in gprs_subscriber.c,
and are used mainly by functions in the same file, hence move it to the
related header to further shrink gprs_sgsn.h.
Change-Id: Iff7be91af130a3317d57d3649c17e3d5d2540e7a
This allows further shrinking of gprs_sgsn.{c,h} and also being able to
use GSM_APN_LENGTH on different headers easily (needed by follow-up
patch).

Rework initialization and destruction of several sgsn subsystems to be
allocated & released together with the struct sgsn_instance.
This makes it easier to destroy and recreate the entire context and
allows us to start moving global variables scattered around to be under
struct sgsn_instance.
Change-Id: Idf60519b8e475b94d38bbb69e737132a5afaefab
Similar to what we already have for struct sgsn_mme_ctx in
gtp_mme.{c,h}.
This is just the nth step of properly splitting different
protocol layers, data model, etc.
Change-Id: Iad1895f09e43e299df7bb126bf52fdb98268392e
All remaining code in that file is NS protocol related, hence let's
rename it so that we end up with one file per protocol in the Gb stack.

Right now there's no much code there since the related code is totally
entangled with the LLC one.
This will eventually change in the future when we switch to use
libosmo-gprs.
Hence, this commit is a preparation to have already some place to put
new BSSGP specific code in the future.

MMEs connect over Gn interface using GTPCv1 towards the SGSN in order to
exchange RIM PDUs by using "RAN Information Relay" GTPCv1 message type.
For more info, see 3GPP TS 29.060 sec 7.5.14.1 "RAN Information Relay"
In order to support it, this commit does the following:
* Uses new libgtp APIs to rx and tx RAN Information Relay messages. The
same "gsn" object is reused, ie. the local GTPCv1 socket address used
for exchanging messages against GGSN is reused.
* Adds a new "sgsn_mme_ctx" struct holding information about MMEs
allowed by the SGSN, each one containing information about the GTP
address it uses, the in/out routing based on TAI requests, etc. The
set of MMEs and their config can be set up using new VTY node introduced
in this commit.
* The RIM related code in SGSN is refactored to allow forwarding from
and to several types of addresses/interfaces.

State machine inspired in the one from TS 24.008 4.1.3.3.1. Some state
transitions are inroduced in the code but are still commented out since
we lack some functionalitites or improvements in the code to handle
different scenarios.
Most of the logic is still outside of the FSM, but at least now the
states are handled in a sane way triggered by events.

Now that we have RANAP/Iu handling specificities in its own file, let's
have also Gb specific glue code for messages coming from llc up to MM/SM
layer in its own file. This way same entry points in gprs_gmm.c are used
by Gb and Iu: gsm0408_rcv_gmm() (for MM) and gsm0408_rcv_gsm() (for SM).

RANAP related functionalities were splitted among several files
(gprs_gmm.c, gprs_sgsn.c and sgsn_libgtp.c). Let's move it into its own
file to shrink complexity/size of existing files.
It also allows to keep a lot of conditionally enabled code (BUILD_IU)
and its dependencies (osmo-iuh) together.

Store the established security context type (GSM or UMTS) instead of the
boolean flag is_authenticated. Provide the previous boolean query with thin
sgsn_mm_ctx_is_authenticated() function.
Knowing which security context was established will be necessary for OS#3224,
i.e. using the proper ciphering key, which is not yet tested properly, and
probably not correct at this stage.
This change will make new SGSN_Tests.TC_attach_umts_aka_gsm_sres pass.
