Oliver Smith b81e6b64ac 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.

Harald Welte e844bf7828 sabp: Generate C/H files for SABP; create libosmo-sabp
This uses the (modified) Osmocom asn1c on the (modified) SABP ASN.1
syntax to generate C code + header files for SABP parsing/encoding.

It also adds some helper code for message encoding and decoding as well
as a new libosmo-sabp shared library which can be used by programs to
implement SABP related functionality.
