Oliver Smith 48c038d399 asn1: fix visibility warnings from generated code
Fix warnings from generated asn1 code in order to build osmo-iuh with
werror in a future patch:

../../include/osmocom/hnbap/HNBAP_CriticalityDiagnostics-IE-List.h:29:23: error: ‘struct HNBAP_CriticalityDiagnostics_IE_List__Member’ declared inside parameter list will not be visible outside of this definition or declaration [-Werror]

These visibility warnings come from "SEQUENCE … OF SEQUENCE" definitions
in the asn1 source files, as described in detail here:
https://github.com/vlm/asn1c/issues/430

It is not possible to tell gcc to just ignore these warnings since they
don't have their own type (unlike e.g. -Wuninitialized). Also it seems
like a huge effort to patch this in asn1c.

So work around the problem the same way the author of the issue worked
around it by rewriting the lines to "SEQUENCE … OF …-Value" and adding
a "…-Value ::= SEQUENCE" line below. Add a script in
asn1/utils/asn1_restructure_sequence_of_sequence.py for the
transformation and apply it.

Philipp Maier ca6054ef8c ranap_common_cn: add functions for direct access to decoder
The message encoder functions that decode a message to a struct
ranap_message are only accessible via a callback function that is passed
to ranap_cn_rx_cx The decoded ranap_message only lives inside the callback
since it is freed by ranap_cn_rx_cx when the callback is done. In some
situations this might make using the decoder incredibly difficult since
it is not possible to keep the decoding results for an extended amount
of time. Lets put the decoding into a separate function and use this
function in ranap_cn_rx_cx. Then lets make the decoder and the free
function public so that the decoder can be used in a more open way.

Neels Hofmeyr aae68b2791 move openbsc.git's iu.h, iu.c, iu_vty.c here as iu_client
To help split openbsc.git to separate MSC and SGSN repositories, place the
common Iu interface related code here in libosmo-ranap. Also apply various
improvements while moving (from intermittent code review).

The code depends on libosmo-ranap tightly. One reason to want this separate
from libosmo-ranap could be that it uses libosmo-sigtran, accepting an sccp
instance. However, including in libosmo-ranap is the simplest way to go. The
osmo-iuh build depends on libosmo-sigtran anyway because of OsmoHNBGW, and all
current users of libosmo-ranap also naturally link libosmo-sigtran already.

Apply prefix ranap_iu_ and RANAP_IU_ to allow smooth transition from the
openbsc.git iu_ to the libranap ranap_iu_ implementations.

Prune unneeded #include statements.

Instead of sccp_addr, store an rnc pointer in the ue_conn_ctx. To facilitate,
also:
- Move iu_rnc struct to iu_client.h (as ranap_iu_rnc).
- Instead of sccp_addr, pass rnc to ue_conn_ctx_alloc().
- Pass a local struct new_ue_conn_ctx containing the sccp_addr and conn_id up
  the RANAP handling stack in case of an InitialUE message.
- Separate the InitialUE message handling from cn_ranap_handle_co(), by moving
  to new and separate cn_ranap_handle_co_initial(), so we can still pass a
  looked-up ue_conn_ctx to all other cn_ranap_handle_co() code paths.
- Allocate the ue_conn_ctx only in ranap_handle_co_initial_ue(), not as early
  as before.
Note that we are not actually ever using the rnc pointer now present in
ue_conn_ctx. It could be used for more concise paging, to first page only the
RNC where we last saw the subscriber. So far we page all matching LAC/RACs.

Tweak error logging: use __func__ instead of writing the function names as
string constants.

In iu_client_vty.c:
- Move the asn.1 debug commands from logging over to the iu node. They are not
  specific to the logging target. They could qualify for an entirely separate
  'asn1' root node, but for simplicity place under 'iu'.
- Add the 'asn1' commands to ranap_iu_vty_config_write(), so far missing.
- remove the legacy "net." from a VTY error message, it is not known which name
  the parent node of 'iu' has.

Neels Hofmeyr 8345792281 build: fix ranap gen, use same for gen hnbap and rua gen
fix extraneous rebuild for each make invocation: touch the ranap.stamp file in
src/ as the make target suggests.

fix for 'make distcheck': ranap gen: move generated sources to builddir, not
srcdir. Thus we also -I the builddir include to pick up those headers.

hnbap and rua have the same situation as ranap (they generate numerous files
from a single make rule). Use the same makefile semantics for those two
(commit for ranap gen omitted the same changes for hnbap and rua).

The generated headers are thus moved to include/osmocom/*/, so adjust #include
statements accordingly (*_common.h, *_ies_defs.h).

Also move hnbap_common.h to include/osmocom/hnbap and rua_common.h to
include/osmocom/rua, since the *_ies_defs.h want to include them; and since
*_ies_defs.h are now in include/osmocom/*, we want a '<foo>' include now.

Also adjust gitignore.

Neels Hofmeyr f6673b7257 RAB Assign for voice: heed the x213 nsap flag
Add use_x213_nsap arg to ranap_new_msg_rab_assign_voice() and
new_transp_info_rtp(). Pass this to new_transp_layer_addr() to compose 32bit
addresses when use_x213_nsap == false.

This is analogous to ranap_new_msg_rab_assign_data().

Particularly, the ip.access nano3G does not accept x213 NSAP 56bit addresses,
so we want to send 32bit addresses there.

Alexander Huemer 156fa393fc attempt to fix parallel build, improve AM logic
The formerly existing make rule caused a race condition in parallel builds and
wrongly stated the .c files as targets, which caused make to execute the
rule twice (once for each target). This was actually only fallout of the
attempt to express the fact that those two files are generated by the rule.

The generated file ranap_ies_defs.h was moved by one make job, another
job then tried to access the file in the old location and failed.

parallel build verified with:
$ for i in $(seq 1 10)
do
	echo "XXXX iteration $i"
	git clean -xfd
	autoreconf -i
	./configure
	make -j${i} || break
done
