Sometimes a fix release may be required which only contains fixes to
parts not related to a shared library, for instance a fix in the build
system. Thus allow releasing without bumping LIBVERSION, but only
through env var setting for people who know what they are doing.

Allow printing the source file information *after* the log information.
Add target->print_filename_pos, log_set_print_filename_pos() and enum
log_filename_pos, and the optional 'last' keyword to the 'logging print file'
vty command. (An enum in case we want to add other positions later.)
Rationale: on log lines, the logging context is usually printed first in the
logging text. Without the source file information, this logging context pretty
much aligns in an easily readable way. When adding the source file information,
each line's logging context info is shifted right by a pretty much random
amount and it is hard to spot recurring logging contexts.
One solution is to switch off source file info, of course, but that's not an
option when actively hacking on bugs and new features.
For example, it is unnecessarily hard to spot lchan FSM related log lines in
this osmo-bsc log snippet:

When gsmtap adding a new sink it does not supply OSMO_SOCK_F_UDP_REUSEADDR
in order to have SO_REUSEADDR applied. In most cases, the gsmtap sink is
just receiving packets to toss them immediately, so having one of them
is sufficient. However, in other use cases - particularly virt_phy -
we actually want to receve and process GSMTAP messages via multicast
Applying SO_REUSEADDR (like we did before disabling it globally for UDP
in I4a8ffb8d598aca88801a4a0322944d7cdd8d4047 on August 1st) resolves
the issue.

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

allocating struct signal_handler into the NULL talloc ctx.

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).

When UDP is used as protocol (proto=IPPROTO_DUP), then we should not set
SO_REUSEADDR in the socket option. Because if we do, we allow two
processes to bind on the same UDP port. The errornous situation will be
undetectable to both applications. So lets only set SO_REUSEADDR when we
do not use UDP.
- Add check if we use UDP, if yes do not set SO_REUSEADDR

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,

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 7f31c90b80.
Revert "ipa: Properly parse LV stream of a ID_GET request"
This reverts commit f558ed4bb9.
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).
