When IPPROTO_UDP is used then SO_REUSEADDR omitted since UDP is
connection less we do not have to wait until lingering connections time
out. There were also negative effects such as that two applicatications
could use the same UDP port, normally one of the two applications would
get an error, but with SO_REUSEADDR this is supressed. However, there
are applications (UDP MULTICAST) where two applications must be able to
use the same port. In the osmocom project those are osmo-bts-virtual,
virtphy and gsmtap in general.
Lets introduce a flag that the API user can supply in order to have
SO_REUSEADDR applied.
- Add new flag OSMO_SOCK_F_UDP_REUSEADDR

The intention was to use the file's basename, but __BASE_FILE__ means "the root
file that is being parsed and contains #include statements".
If we had a function using __BASE_FILE__ and that was defined in an #included
file, __BASE_FILE__ would indicate the first file where the #include is, and
not the file where the function is defined. __BASE_FILE__ works for us because
we don't ever include function definitions that log something, so __BASE_FILE__
always coincides with __FILE__ for our logging; but still __BASE_FILE__ is
semantically the wrong constant.

It's a common pattern having a list of msgb and having to maintain its
size (for instance, to limit the maximum size of the list). Having the
counter updated at the same time that the msgb is enqueued or dequeued
helps avoiding introducing new bugs by forgetting to update the size
counter at the right places.

Otherwise applications need to use "extern void* tall_sigh_ctx" and set
it manually (that symbol is not exported in any header file) or end up
allocating struct signal_handler into the NULL talloc ctx.
API created in a similar way as already existing msgb_talloc_ctx_init(),
but without the pool_size because it's not considered necessary in this
case.

To reset the state of BSSGP allow to flush the BSSGP queues.
When testing (with TTCN3) the test object should be resetted between
each test.
Introduce the functions:
bssgp_fc_flush_queue() - flushs a single flow control object
bssgp_flush_all_queues() - flushs queues of all BSSGP connections

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 the previous commit we deprecated ipa_ccm_idtag_parse() but
also removed ipa_ccm_idtag_parse_off(), for which I couldn't find
any users. However, legacy openbsc.git still uses this function,
so let's re-introiduce it in its original form.

In the past, the function ipa_ccm_idtag_parse() was used to parse
the payload of IPA CCM ID RESP packets. However, the function was
based on a possible misunderstanding of the message encoding, and
callers actually counted the first (upper) length nibble as part
of the header and passed a pointer to the second
(lower) length nibble of the first TLV into this function. As such,
it was unfixable, and had to be replaced with a new function called
ipa_ccm_id_resp_parse(). At the same time, we also add
ipa_ccm_id_get_parse() to parse the slightly different format of
the IPA CCM ID GET payload.
We can never be 100% sure what is "correct", as our understanding
of the protocol is entirely based on protocol analysis, without any
official documentation available.
This patch also introduces unit test coverage for both of the new
functions.
Revert "ipa: Add libosmogsm.map entry for ipa_ccm_idtag_parse_off"
This reverts commit 7f31c90b80c08fbfe2d84d70d397402fdb38b94c.
Revert "ipa: Properly parse LV stream of a ID_GET request"
This reverts commit f558ed4bb9c0f00997b8f97c2b251a574c1a64c4.
It introduced a function/behavior that was not originally intended:
The parse of IPA CCM ID GET (8bit length followed by 1 byte tag
and variable-length payload) instead of the IPA CCM ID RESP (16bit
length followed by 1 byte tag and variable-length payload).

Contrary to the existing gsm0480_create_ussd_resp(), the new function
only generates the value part of the FACILITY IE, and not the IE
Tag/Length or the 04.08 L3 header. This is needed in the context of
GSUP-encapsulated USSD, as here we don't work with L3 messages, but
only pass on the FACILITY IE value.

In SIMtrace 1 the ATR was sent the same way as an APDU.
The ATR is not an APDU, and could be mis-interpreted as valid APDU.
This change allows to make the difference between actual APDU and
the ATR, but also adds sub_types for future SIMtrace 2 use cases.

The conv_gen.py utility was tested against both Python 2 and 3,
so there is no need to enforce Python 2. Also, having:
#!/usr/local/bin/python{2|3}

In Change-Id I5a70eb65952cbc329bf96eacb428b07a9da32433 we redirected
all OSMO_ASSERT() via osmo_panic(). However, this caused various
applications to have build failures, as OSMO_ASSERT() now appeared
to be able to return to the call site. Let's inform the compiler
explicitly that there's no return from osmo_panic().

A loooong time ago, we introduced osmo_panic() as a wrapper around
abort(). The advantage is, that this wrapper can be overridden, and
that it will also work in embedded (bare iron) targets, where the
abort simply translates to an infinite loop.

This function permits the user to register deprecated log categories,
which will ensure that if log categories are removed from a program,
old config files will still load.
We simply dynamically allocate a cmd_element and install it at
CFG_LOG_NODE. Not registering it at VIEW_NODE or ENABLE_NODE
ensures that it's not accessible from the interactive VTY, but only
from the config file / configure node.

The general idea about each osmo_fsm_instance having a separate
log-level was to be able to selectively increase/show/enable logging
for some FSM instances (e.g. of a particular subscriber) while
maintaining normal logging verbosity for all other instances of the
same FSM.
The introduction of LOGPFSML() in Change-Id
If295fdabb3f31a0fd9490d1e0df57794c75ae547 broke that idea, as it would
use a compile-time log level, irrespective of the
osmo_fsm_inst.log_level setting of the given instance.
Let's combine the two:
Use the explicit level stated at LOGPFSML(), _unless_ this instance
has a higher log_level configured.
This way, all FSMs should normally be created with
osmo_fsm_inst.log_level == LOGL_DEBUG. At that point LOGPFSM()
statements would be rendered at debug level, typically below the
threshold of most logging configurations.
Code that has explicit higher log levels like LOGPFSML(fi, LOGL_ERROR)
would always be printed, as it is an error message.
And if we now increase the osmo_fsm_inst.log_level, then even the normal
LOGPFSM() statements would suddenly be logged at that higher level,
selectively increasing log verbosity - like originally intended.

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.
