So far we had a function to allocate a new bssgp_bvc_ctx, but not
the opposite one. Let's finally introduce it, so it will be used
at least in OsmoPCU.
Please note that the new symbol has 'bssgp_' prefix, not 'btsctx_'.

This is useful for timers expected to have a range of valid or expected
values.
Validation is done at runtime when timer values are set by the app or by
the user through the VTY.

The intention of osmo_tdef_get()'s val_if_not_present argument was to return a
default timeout, or to optionally abort the program for missing timer
definitions if the default timeout is < 0. This was the case in the original
implementation of this API in osmo-bsc, but in the migration to libosmocore,
the argument was by accident changed to an unsigned type. In consequence, the
assertion in the implementation that was intended to abort the program seemed
bogus to coverity, and was fixed by removal in
I7a544d2d43b83135def296674f777e48fe5fd80a -- the wrong direction, as is obvious
from the API doc for osmo_tdef_get().
Note that osmo-bsc master passes -1 in various places and expects the
program-abort behavior that was missing from the libosmocore implementation.
Change the val_if_not_present argument to a signed type, and revert removal of
the assertion, so that passing -1 has the effect described in the API doc:
program abort on missing timer definition.
This bug was not detected because it is hard to write tests that expect a
program abort to happen, hence no tests for this API feature exist.

Change two instances of Speech Version values to enum gsm0808_permitted_speech.
It is often not trivial to find the right values for a uint8_t member, giving
the enum name makes it a lot easier/safer to use.
In gsm0808_create_handover_required(), use msgb_tv_put() so that the enum's
storage size doesn't matter. (Already used for handover_performed)
Fix typo in doc of gsm0808_create_handover_required().

To be able to append an escaped or quoted string using
OSMO_STRBUF_APPEND_NOLEN(), the function signature must have the buf and len as
first args, like most other *_buf() functions.
Add osmo_escape_str_buf2() and osmo_quote_str_buf2() to match this signature.
A recent patch [1] has changed the return value of osmo_escape_str_buf() to
char*, removing the const. However, the functions may return const strings,
hence re-add the const. The new signatures always return the non-const buffer.
To avoid code duplication, implement osmo_quote_str_buf() and
osmo_escape_str_buf() by calling the new functions.
I decided to allow slight changes to the behavior for current osmo_escape_str()
and osmo_escape_str_buf(), because impact on callers is minimal:
(1) The new implementation uses OSMO_STRBUF_*, and in consequence
osmo_quote_str() no longer prints an ending double quote after truncated
strings; Before, a truncated output was, sic:
"this string is trunca"
and now this becomes, sic:
"this string is truncat
I decided to not keep the old behavior because it is questionable to begin
with. It looks like the string actually ended at the truncation boundary
instead of the reason being not enough space in the output buffer.
(2) The new osmo_escape_str_buf2() function obviously cannot pass-thru an
unchanged char* if no escaping was needed. Sacrifice this tiny optimization
feature to avoid code duplication:
- it is an unnoticeable optimization,
- the caller anyway always passes a string buffer,
- the feature caused handling strings and buffers differently depending on
their content (i.e. code that usually writes out strings in full length
"suddenly" truncates because a non-printable character is contained, etc.)
I considered adding a skip_if_unescaped flag to the osmo_quote_str_buf2()
function signature, but in the end decided that the API clutter is not worth
having for all the above reasons.
Adjust tests to accomodate above changes.

To prevent re-entering osmo_fsm_inst_term() twice for the same osmo_fsm_inst,
add flag osmo_fsm_inst.proc.terminating. osmo_fsm_inst_term() sets this to
true, or exits if it already is true.
Update fsm_dealloc_test.err for illustration. It is not relevant for unit
testing yet, just showing the difference.

The NS implementation part of the Gb implementation libosmogb
so far implemented a rather classic dialect of Gb, with lots of
heritage to FR (Frame Relay) transports. At least since Release 6
of the NS specification, there's an IP Sub-Network Service (SNS),
which
* permits for dynamic configuration of IP endpoints and their NS-VCs
* abandons the concept of a NSVCI on IP transport
* forbids the use of RESET/BLOCK/UNBLOCK procedures on IP transport
This commit introduces BSS-side IP-SNS support to libosmogb in a
minimally invasive way. It adds a corresponding SNS FSM to each NS
instance, and implements the new SIZE/CONFIG/ADD/DELETE/CHANGE_WEIGHT
procedures very closely aligned with the spec.
In order to use the SNS flavor (rather than the classic one),
a BSS implementation should use gprs_ns_nsip_connect_sns() instead
of the existing gprs_ns_nsip_connect().
This implementation comes with a set of TTCN-3 tests in
PCU_Tests_RAW_SNS.ttcn, see Change-ID

Previously it could encode both incorrect values as well as incorrect
message. Let's fix this by explicitly checking for invalid values and
ensuring that at least one of the parameters is valid.
This function have no external or internal users so it's better to fix
type signature as well to match the rest of gsm0808_create_lcls_*().

According to 3GPP TS 29.002, there are two services:
- MAP-MO-FORWARD-SHORT-MESSAGE (see 12.2),
- MAP-MT-FORWARD-SHORT-MESSAGE (see 12.9),
which are used to forward MO/MT short messages.
This change replicates both services as GSUP messages:
- OSMO_GSUP_MSGT_MO_FORWARD_SM_*,
- OSMO_GSUP_MSGT_MT_FORWARD_SM_*.
Please note, that only the 'must-have' IEs are introduced
by this change, in particular the following:
- OSMO_GSUP_SM_RP_MR_IE (see note below),
- OSMO_GSUP_SM_RP_DA_IE (see 7.6.8.1),
- OSMO_GSUP_SM_RP_OA_IE (see 7.6.8.2),
- OSMO_GSUP_SM_RP_UI_IE (see 7.6.8.4),
- OSMO_GSUP_SM_RP_MMS_IE (see 7.6.8.7),
- OSMO_GSUP_SM_RP_CAUSE_IE (see GSM TS 04.11, 8.2.5.4),
where both SM_RP_DA and SM_RP_OA IEs basically contain
a single nested TV of the following format:
- T: identity type (see 'osmo_gsup_sms_sm_rp_oda_t'),
- V: encoded identity itself (optional).
According to GSM TS 04.11, every single message on the SM-RL has
an unique message reference (see 8.2.3), that is used to link
an RP-ACK or RP-ERROR message to the associated (preceding)
RP-DATA or RP-SMMA message transfer attempt.
In case of TCAP/MAP, this message reference is being mapped to the
Invoke ID. But since GSUP has no 'Invoke ID' IE, and it is not
required for other applications (other than SMS), this change
introduces a special 'SM_RP_MR' IE that doesn't exist in MAP.

There is already a group of similar functions for L1, L2 and L3,
but L4 was missing. The L4 is usually used for parsing of complex
L3 messages, such as SS/USSD and SMS.
This change introduces a similar halper for L4.

There was gsm0480_l3hdr_push() declared in a header file, but
not exposed in 'libosmogsm.map'. Furthermore, for some reason
it was a part of GSM 04.80 API, what is not actually correct.
Let's rename this symbol, and properly expose it as a part of
the GSM 04.08 API. Also, let's introduce an auxiliary wrapper
for messages, where the transaction identifier is required
(see GSM 04.07, section 11.2.3.1.2).

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.

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.

As it was already documented before, the 'ss_request' struct has
a rudiment of deprecated 'ussd_request' struct - the 'ussd_text'
field. It represents the data either of an INVOKE component,
either of a RETURN_RESULT component, encoded as ASCII in case
if DCS is 0x0f (i.e. decoded by the code itself), otherwise
raw bytes 'as is'.
Previously, there was no possibility to distinguish between
ASCII and raw bytes with different DCS. Moreover, the payload
decoding is not desired in some cases.
Let's introduce the new fields, which will carry the raw
unmodified payload, its length and DCS (Data Coding Scheme).

The function _osmo_fsm_inst_term() terminates all child FSMs befor
it calls fi->fsm_cleanup(). This prevents the cleanup callback to
perform last actions on the child FSMs (e.g.
osmo_fsm_inst_unlink_parent()).
- Since moving the cleanup callack to the beginning of the function
would alter the termination behavior and possibly cause malfunction
in already existing implementation that use OSMO fsm, a new
optional callback that is called immediately at the beginning of
the terminatopn process is added.

When listening for nsip connections is enabled, then every remote
host may send packets. This is useful for an SGSN that serves
multiple PCUs, but contraproductive for a PCU that awaits packets
from a single SGSN.
Add struct members remote_ip, and remote_port to struct gprs_ns_inst,
when set, then the listening end uses connect() to ensure that only
the expected host may send packets.

GSUP transmits AUTS for UMTS authentication procedures, and OAP uses the same
procedures to authenticate. osmo-gen-vec is a utility program that passes AUTS
to our osmo_auth_gen_vec_auts() API.
According to 3GPP 33.102 6.3.3, AUTS = SQN^AK || MAC-S, which are 6 || 8 == 14
bytes. This is confirmed by 24.008 9.2.3a where the TLV has 16 bytes, TL = 2
and AUTS being the V = 14.
It is not harmful for milenage_gen_vec_auts() to pass two more AUTS bytes. But
writing 16 bytes to a GSUP struct is a potential problem when passing in a 14
byte long AUTS buffer to the GSUP API, which then reads past the AUTS buffer.
The API implies the length, so far to be 16, so passing in a 14 byte buffer to
GSUP would require copying to a larger buffer first.
Fix this by using a length of 14 for AUTS everywhere instead.
This constitues an ABI breakage, we may handle it as a "fix before an official
release", otherwise we need a version bump.
The OAP protocol document has also been updated, needs an update in the
osmo-gsm-manuals as well.

This reverts commit ed9d6da5df98538adc70aa03cb569eb9505d04b6.
The commit is good as such, but it causes many compiler warnings in the OpenBSC
build. We want this to be re-applied as soon as we have patches ready that fix
the fallout in openbsc.git.

Update internal API (for GPRS cipher implementors): make it compliant
with ETSI TS 155.22. External API left untouched.

Previously the presence of header and data blocks were communicated
in-band which decreases code readability and makes it unnecessary hard
to add support for new hardware.
Note: OsmoBTS have to be modified to take advantage of extended
ph_data_param structure.

Shipping our own private copy of talloc was a good idea in 2008,
when it was not readily available on most target platforms. Today,
the situation is quite different, as it is a standard library on
major Linux distributions.

Currently every time a node is added to enum node_type, this
constitutes an ABI change, since _LAST_OSMOVTY_NODE will get
incremented accordingly. In this case, every project that adds new
node type based on that value will have to be recompiled.
This commit adds 4 spare node type values, which can be replaced
one-by-one by new real types until they are exhausted to avoid
this kind of ABI change.

This commit provides stats configuration similar to the log
configuration.
The following vty commands are added to the config node:
stats reporter statsd Create/Modify a statsd reporter
no stats reporter statsd Remove a statsd reporter
To actually configure a reporter, the config-stats node is entered
when the "stats reporter" command has succeeded. The following new
vty commands are available there:
local-ip ADDR Set the IP address to which we bind locally
no local-ip Do not bind to a certain IP address
remote-ip ADDR Set the remote IP address to which we connect
remote-port <1-65535> Set the remote port to which we connect
prefix PREFIX Set the item/counter name prefix
no prefix Do not use a prefix
enable Enable the reporter
disable Disable the reporter
