This change adds a check whether compiler supports some SIMD
(Single Instruction, Multiple Data) instructions. It is enabled
by default, and can be disabled by configure option --disable-simd.
The check macro is based on the AX_EXT from autoconf-archive:
www.gnu.org/software/autoconf-archive/ax_ext.html
And depends on the ax_check_compile_flag macro:
www.gnu.org/software/autoconf-archive/ax_check_compile_flag.html
Currently only the following SIMD extensions are being checked:
AVX2, SSE3, SSE4.1, but adding others is also possible. All found
extensions are being defined in the 'config.h' header.

This change extends the convolutional code test coverage, adding
the GSM 05.03 specific test vectors, generated by the conv_gen.py.

* data structure representing 3GPP TS 52.021 §9.4.62 SW Description
* function to serialize it into msgb
* function to deserialize it from buffer
* functions to extract/estimate buffer size for SW Description
* test harness (partially taken from OpenBSC)
There are several similar functions to deal with SW Description in
OpenBSC, there's also need to use similar functionality in
OsmoBTS. Hence it's better to put the code into common library with
proper tests and documentation.

There are some projects, such as GR-GSM and OsmocomBB, which would
benefit from using one shared implementation of GSM 05.03 code. So,
this commit introduces a new sub-library called libosmocoding, which
(for now) provides GSM, GPRS and EDGE transcoding routines, migrated
from OsmoBTS.
The original GSM 05.03 code from OsmoBTS was relicensed under
GPLv2-or-later with permission of copyright holders (Andreas Eversberg,
Alexander Chemeris and Tom Tsou).
The following data types are currently supported:
- xCCH
- PDTCH (CS 1-4 and MCS 1-9)
- TCH/FR
- TCH/HR
- TCH/AFS
- RCH/AHS
- RACH
- SCH

Since we have automatic header generation, implemented in the
utils/conv_gen.py, it's time to use this feature!

The write queue was always meant to not queue more than the
max_length messages but the implementation never rejected a
message.
Begin to log and enforce the queue size limit, add a testcase
to verify the code and initialize except_cb as part of a fix
for that new test case.
Real applications might now run into the queue limit and drop
messages where they just queued them before. It is unfortunate
but I still think it is good to implement the routine as it was
intended. We need to review osmo_wqueue_enqueue once more to
see that no msgb is leaked.

Instead of generating every convolutional code into a separate
file (such as conv_xcch_gen.c, conv_cs3_gen.c), it is better to
have a single file, containing all definitions, because as many
convolutional codes we add, as many entries we will have to add
into 'src/gsm/Makefile.am'. This approach increases readability
of the Makefile.am, and also makes us able to share some data
between some convolutional code definitions.
For example: xCCH, RACH, SCH, TCH/F, both CS2 and CS3 may use
the same *_state[][2] and *_output[][2] arrays within a single
file. This optimization is currently WIP.

Corresponding test code include both official test vectors from the
specs and data from over-the-air tests.
This obsoletes libosmo-crypt-a53 as it was last missing piece
unimplemented in libosmogsm.

* add functions to encode/decode various codec paramters from RTP payload with
AMR frame according to RFC 4867
* those functions are extended version based on code from osmo-bts'
amr.c by Andreas Eversberg
* add corresponding enum types and strings for logging
* add regression tests
It's useful both to replace manual parsing in osmo-bts with fuctions
covered by test suite and as a debugging helpers for issues related to
AMR.

Add python utility to generate .c code with convolutional
encoder/decoder based on polynomial description of the code. If argument
given it'll be interpreted as intended output directory, otherwise
current working directory is used.
Codes for *CCH, CS2/3 and TCH/AFS are generated. Corresponding manual
implementations are removed from tests. This introduce build-time
dependency on python.
The main work for this patch was generously contributed by Sylvain
Munaut.
Fixes: OS#1629
Add bit map encoder and decoder functions: decoder is fully functional
while encoder is good enough for testing - no backtracking to find
the best possible compression is implemented. If somebody is willing to
implement MS side of EDGE than this has to be expanded.
Add corresponding tests.
N. B: the encoding is implemented according to ETSI TS 44.060 which is
slightly different from T4 used for fax according to CCITT G31D (RFC 804).

This commit adds instrumentation function to gather measurement
and statistical values similar to counter groups.
Multiple values can be stored per item, which can be retrieved in
FIFO order. Getting values from the item does not modify its state to
allow for multiple independant backends (e.g. VTY and statd).
When a new value is set, the oldest value gets silently overwritten.
Lost values are skipped when getting values from the item.

Test yields ok, but the current implementation doesn't properly support
multi-character separators and end strings. So the test output is truncated.

The framerelay code is seldomly used and the socket clean ups introduced
a regression. Create a testcase that will work as a user not having the
right capabilities to create raw sockets.
We have to make sure that this test is working even when not ran as root.
The easiest way to do this is to provide our own socket implementation.
This is done with dlopen/dlsym to convert the raw socket request to an UDP
one.
When building the doxygen documentation do not remove the other
VTY documentation files in the doc/vty folder. Create a command
that can be installed to dump all nodes and commands as XML on
the given VTY. Create a schema for the XML file and a XSL-T script
that can merge the generated file with additional information.
Instead of using a ./configure parameter to decide whehter to build
tests or not, use the check_PROGRAMS variable so that the tests are
only built when running `make check`.
To avoid slowing down the test phase itself, collapse the declaration
of the test targets in the tests/Makefile.am file, this way they can
be built and linked in parallel before the testsuite is executed.

This tests verifies the content of the GSM 08.08 messages, it does
not verify the remaining headroom (which the SCCP/IPA code relies
on being plenty to prepend the header). More to come in the future.
This is testing the establishment of two ends (BTS, MS) one is in
the polling mode as used by osmo-bts. Transfer data between the two
ends. The sent data is not verified though. This should be followed
up soon.
The output of make check is looking like this now:
Regression tests.
