In order to be able to transfer SS/USSD messages via GSUP,
this change introduces the following new message types:
- OSMO_GSUP_MSGT_PROC_SS_*,
and the following new IE:
- OSMO_GSUP_SS_INFO_IE
which represents an ASN.1 encoded MAP payload coming to/from
the mobile station 'as is', without any transcoding.

Unlike TCAP/MAP, GSUP is just a transport layer without the
dialogue/context. This prevents us from having session based
communication, required e.g. for USSD. But we can emulate
TCAP dialogue by adding additional IEs, which would allow
to relate each message to a particular session.
This change introduces the following IEs:
- OSMO_GSUP_SESSION_ID_IE,
- OSMO_GSUP_SESSION_STATE_IE,
which optionally can be used to indicate that the message is
related to a session with given ID, and to manage session
state, i.e. initiate, continue, and finish.

According to the 3GPP TS 04.80, table 2.5 'Release complete', a
RELEASE_COMPLETE message may containg optional FACILITY element.
Meanwhile, the 0xff byte is used to indicate that there is no
decoded message (legacy field). Let's avoid overwriting of
a decoded message.

The idea is to be able to add a gsm0808_cell_id to a gsm0808_cell_id_list2:
first convert it to a list, then re-use gsm0808_cell_id_list_add(). It will be
used by osmo-bsc to manage neighbor-BSS cell identifiers from VTY.

The kasumi_test is updated to calculate the entire array of bits
according to expected result. Before this commit it worked by writing
the entire last 64bit block, and addressSanitizer cannot catch it
because the allocated buffer is 64bit aligned too.

The FSM allows to set individual action callback functions for each
state but it does not allow to leave the action callback pointer
unpopulated. However, there are cornercases where having no callback
function is desirable.
- Check if action callback is popolated before executing it.

Linux offers file descriptor based periodic (interval) timers,
which can achieve a higher precision than our userspace based
timers and which can be slave'd to CLOCK_MONOTINIC or other clock
sources. Let's add some code for osmo_fd wrapped versions that
integrate well with our select() abstraction.
The code has been used in osmo-bts-trx since June 2017 (change-id
I51b19adde14ebb7ef3bb863d45e06243c323e22e), and I'm just renaming
and moving it to libosmocore here. After a merge, the osmo-bts
implementations can be removed in favor if this one.

In Change-Id: I8c2c103cdc7f9a45d7b2080c572f559fc3db58e4 we introduced
a check to enforce contention resolution always being used in
MS-originated LAPDm establishment on the main DCCH / SAPI0. This is
only required after RACH request (IMM.ASS.) and not after a normal
assignment command which was sent already via a dedicated channel.
Hence, we cannot enforce a strict requirement for contention resolution
in those cases.
We *could* use the RSL Channel Activation type as a constraint on
whether or not to enforce contention-resoluiton-only LAPDm
establishment, but this is out of the scope of the LAPDm code but would
have to be done inside OsmoBTS.

The RSL_IE_MS_POWER / RSL_IE_TIMING_ADVANCE is how we communicate
the SACCH L1 header values on the MS side between LAPDm and L3 (which
is a non-standard use of RSL).
However, those IEs only maek sense on the SACCH, where we have B4 frame
format and where we actually have a L1 header containing related
information. Let's make sure to skip those IEs on regular RLL UNIT DATA
INDICATION happening on other channel types.

gsm0808_permitted_speech() is moved from osmo-bsc's bssap_speech_from_lchan();
gsm0808_chosen_channel() is moved from osmo-bsc's lchan_to_chosen_channel();
Rationale: will be re-used by inter-BSC handover, makes sense to keep with the

Imagine following scenario:
1- client connects to CTRL iface, a new conn is created with POLL_READ
enabled.
2- A non-related event happens which triggers a TRAP to be sent. As a
result, the wqueue for the conn has now enabled POLL_WRITE, and message
will be sent next time we go through osmo_main_select().
3- At the same time, we receive the GET cmd from the CTRL client, which
means POLL_READ event will be also triggered next time we call
osmo_main_select().
4- osmo_main_select triggers osmo_wqueue_bfd_cb with both READ/WRITE
flags set.
5- The read_cb of wqueue is executed first. The handler closes the CTRL
conn for some reason, freeing the osmo_fd struct and returns.
6- osmo_qeueue_bfd_cb keeps using the already freed osmo_fd and calls
write_cb.
So in step 6 we get a heap-use-after-free catched by AddressSanitizer:

Before this commit, for library projects (containing LIBVERSION in some
Makefile), the entire commit list was not stored into the changelog, but
only a few lines from TODO-RELEASE files.
This is a bad approach for several reasons. First, because that file was
only aimed at containing API/ABI breaks, and not the full relevant
changeset (like bugfixes, new features, etc.). Second, because it relies
on every developer making API/ABI changes to remember to store the
change in there during commit break time.
Let's instead always store the entire commit list in changelog, and
let's use TODO-RELEASE only as a list of hints for the maintainer to
help him evaluate how LIBVERSION needs to be bumped for each library.
Other tools such as osmo-abi-check.git can be used to help with the
process of decission too.
Let's take the opportunity too to only commit stuff already added to the
staging area, as it proved easier to manage from my personal experinece
making latest releases.

It turns out git status doesn't return an error code in any of the
modified/unmodified cases. It's not clear anyway why we check
TODO-RELEASE when we actually care about the file containing the
LIBVERSION (non-)change.

param) and as a result no new version entry is created in the log, and
the old one is updated.

gnutls_global_init must be called at least once for
gnutls < 3.3.0. It doesn't hurt calling it twice, except
a reference counter is increased.
gnutls >= 3.3.0 will call it automatic.
