Coverity Scan reported a control flow issue in line 206:
CID 166898: Control flow issues (DEADCODE)
The second branch of the if statement can not be reached. The
purpose of the second if branch was to filter out zero length
elements if the header states that it is a non extended speech
codec type. This makes no sense, since the header needs at
least one byte.
This patch removes the second if branch, zero length elements
are catched by the already existing zero length check at the
beginning of the function

The '__builtin_cpu_supports' is a GCC's built-in function which
returns a positive integer if the run-time CPU supports specified
SIMD feature and returns 0 otherwise. It is required for further
SSE optimization of Viterbi decoder.
This change adds a new check, whether compiler supports this call.
See /gcc/X86-Built-in-Functions.html at gcc.gnu.org for reference.

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.

The alligned memory allocation is only required for SSE, which
is currently unsupported. Moreover, it's better to use dedicated
_mm_malloc() and _mm_free() from xmmintrin.h instead, which are
introduced by Intel specifically for SIMD computations.

Recent changes to libosmoctrl resulted in ctrl comands being broken
because local lookup helper returned incorrect value for ROOT_NODE.
Note: although this commit seems to fix it for me, I'm still not sure
how the logic behind lookup function return values work. Would be nice
to get it documented.

* 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.

We are allocating a buffer on the stack without initializing it, and
then passing it into ipa_ccm_make_id_resp(). There is no real danger
from this, as the buffer is only uninitialized if num_ies is 0, but
let's memset() it for good style

This allows programmatic access to introspection of FSM instances, which
is quite handy from e.g. external test cases: Send a message to the
code, then use the CTRL interface to check if that message has triggered
the right kind of state transition.

Sometimes (particularly when testing), we may want to parse+execute an
arbitrary control command simply form a string buffer, rather than from
a msgb. Let's add a helper for that.

The existing code assumes that the main application knows about all
control command nodes and can thus present one lookup function.
As libraries are getting their own control interface handling, this
is too restrictive, and we need a way how library code can dynamically
register more node lookup helpers. We can now do this by means of a
ctrl_lookup_register() function.

If the user starts the FSM timer with a given timer number during
fsm_inst_state_chg() with a timeout, we should remove that "T" number
after timer expiration. Otherwise it might be confusing if e.g. the VTY
interface shows FSM instances with a certain timer number assigned, but
that timer is not actually running anymore.

The ipa.c file already contained code to parse an ID RESPONSE into the
'struct ipaccess_unit', but it didn't so far contain code to put
together an ID RESPONSE packet based on that structure. Let's change
that with ipa_ccm_make_id_resp() and a helper wrapper
ipa_ccm_make_id_resp_from_req().

Add a separate, faster convolution decoding implementation for rates
up to N=4 and constraint lengths of K=5 and K=7, which covers the
most GSM code uses. The decoding algorithm exploits the symmetric
structure of the Viterbi add-compare-select (ACS) operation - commonly
known as the ACS butterfly. This shift-register optimization can be
found in the well-known text by Dave Forney.
Forney, G.D., "The Viterbi Algorithm," Proc. of the IEEE, March 1973.
Implementation is non-architecture specific and improves performance on
x86 as well as ARM processors. Existing API is unchanged with optimized
code being called internally for supported codes.
The original code was relicensed under GPLv2-or-later with permission
of copyright holder - Tom Tsou.

The old osmo_sock_init() function allows only either a bind (for a
server socket), or a connect (for a client socket), but not both
together. So there's no way to have a client socket that is bound to a
specific local IP and/or port, which is needed for some use cases.

Instead of returning maxfd, which is the highest fd ever seen, take
the highest we have seen on this iteration.
This makes a tiny difference for the osmo-sip-connector and its
event loop integration. select.c ignores the return value of this
function right now.
This was seen while debugging the eventloop integration of the
osmo-sip-connector before and after a VTY connection. The fds
being polled didn't go down.

To make sure that new patches don't break a build done in another dir than
srcdir, make jenkins verify that it still works.
Even though 'make distcheck' also tests a build from a separate dir, this does
not verify that BUILT_SOURCES are generated properly. If these already exist in
the source tree from a previous 'make' issued in the source tree, the
BUILT_SOURCES are not regenerated during 'make distcheck'. Hence a separate
test run is necessary to ensure stability of new patches.
