This way libosmocore build fails during configuring phase if expected
default behavior (building with libsctp support enabled and providing
osmo_sock_init2_multiaddr() API) fails. User is still provided with
--disable-libsctp option in case he doesn't need those features or his
environment doesn't provide required libsctp APIs.

This API will be used by libosmo-netif's osmo_stream for SCTP sockets,
which in turn will be used by libosmo-sccp to support multi-homed
connections.

log_enable_multithread() enables use of locks inside the
implementation. Lock use is disabled by default, this way only
multi-thread processes need to enable it and suffer related
complexity/performance penalties.
Locks are required around osmo_log_target_list and items inside it,
since targets can be used, modified and deleted by different threads
concurrently (for instance, user writing "logging disable" in VTY while
another thread is willing to write into that target).
Multithread apps and libraries aiming at being used in multithread apps
should update their code to use the locks introduced here when
containing code iterating over osmo_log_target_list explictly or
implicitly by obtaining a log_target (eg. osmo_log_vty2tgt()).

Some toolchains (such as sysmobts 201705 one) containing the TLS bug on
old ARM gcc versions (<7.3.0) also crash if the initial workaround found
is aplied (CFLAGS="-mtls-dialect=gnu2"). In that scenario, let's provide
a way to disable the workaround (to avoid "ld" crashing) and warn the
user about requirement to build with -O0 to avoid runtime crashes.

Check if compiler being used contains the bug. GCC 7.3.0 is the oldest
version containing the fix, and version 6.3.0 is known to contain the
bug. Bug is only known to appear so far only on ARM32. If the bug is
present, gcc will generate a wrong binary which wil lend up segfaulting
when accessing TLS (__thread) variables under certain conditions.

For handling RTP IP addresses and ports, osmo-mgw, osmo-bsc and osmo-msc
so far have their own separate shims and code duplication around
inet_ntoa(), htons(), sockaddr conversions etc. Unify and standardize
with this common API.
In the MGW endpoint FSM that was introduced in osmo-bsc and which I
would like to re-use for osmo-msc (upcoming patch moving that to
osmo-mgw), it has turned out that using char* IP address and uint16_t
port number types are a convenient common denominator for logging,
MGCP message composition and GSM48. Ongoing osmo-msc work also uses this
for MNCC.
This is of course potentially useful for any other IP+port combinations
besides RTP stream handling.
Needless to say that most current implementations will probably stay
with their current own conversion code for a long time; for current
osmo-{bsc,msc,mgw} work (MGW endpoint FSM) though, I would like to move
to this API here.

I am setting out to refactor various details about logging. To show the effect,
I am first adding this new test to illustrate the exact effects on the various
osmo programs.
Add logging_vty_test.c as a standalone program that simply defines a few
logging categories and opens a telnet vty to play with.
Add logging_vty_test.vty, as an osmo_verify_transcript_vty.py test script.
Add --enable-external-tests to configure.ac, to enable running
logging_vty_test.vty during 'make check'.
Also allow running 'make vty-test' without the need to first configure with
--enable-external-tests (a flexibility I've missed many times over in the other
osmo source trees).
Add a Makefile.am stub for external CTRL tests, basically a copy-paste from
osmo-msc.git. I doubt that libosmocore will get python driven CTRL interface
testing any time soon, but if so we will know to not run it concurrently.

Linux offers file descriptor based periodic (interval) timers,
which can achieve a higher precision than our userspace based
timers and which can be slave'd to CLOCK_MONOTINIC or other clock
sources. Let's add some code for osmo_fd wrapped versions that
integrate well with our select() abstraction.
The code has been used in osmo-bts-trx since June 2017 (change-id
I51b19adde14ebb7ef3bb863d45e06243c323e22e), and I'm just renaming
and moving it to libosmocore here. After a merge, the osmo-bts
implementations can be removed in favor if this one.

Sometimes the library probiding dlopen is not the same one providing
dlsym.
This is the case when compiling with AddressSanitizer enabled. In this
case, AC_SEARCH_LIBS([dlopen]...) reports no lib is required, but tests
using dlsym still require to link against -ldl.

Provide a sane means of adding the -Werror compiler flag.
Currently, some of our jenkins.sh add -Werror by passing 'CFLAGS="-Werror"',
but that actually *overwrites* all the other CFLAGS we might want to have set.
Maintain these exceptions from -Werror:
a) deprecation (allow upstream to mark deprecation without breaking builds);
b) "#warning" pragmas (allow to remind ourselves of errors without breaking
builds)
As a last configure step before generating the output files, print the complete
CFLAGS and CPPFLAGS by means of AC_MSG_RESULT.

The accelerated convolutional decoder uses SSSE3 instructions such
as PSIGNW (via _mm_sign_epi16) which go beyond what SSE3 offers. So
let's make sure we use the right compiler flag (-mssse3) and also the
right runtime check.
Without this patch, we would use illegal instructions e.g. on Opteron
Gen3 such as Opteron 2427, which are also used as build.opensuse.org
build hosts (build31 through build36) where we wouldn't pass "make
check" as a result.

On systems with GNU/Linux kernel older than 3.17 (Debian 8 "jessie" for
example) the osmo_get_rand_id() would always return failure due to
missing getrandom() syscall.
To support such systems, let's add fallback code which uses GnuTLS
library. It can be disabled explicitly via '--disable-gnutls' option at
compile-time, otherwise ./configure will fail if both getrandom() and
GnuTLS are not available. When building with '--enable-embedded' the
fallback is disabled automatically.

The function is a wrapper on top of getrandom() (if available via glibc) or
corresponding syscall. If neither is available than failure is always
returned.
It's intended to generate small random data good enough for session
identifiers and keys. To generate long-term cryptographic keys it's
better to use special crypto libraries (like GnuTLS for example)
instead.
As an example it's used to replace old insecure random number generator
in osmo-auc-gen utility.

Add simple helper target to automate basic release steps:
* version bump
* prepare release commit
* git commit, tag and sign
For library projects:
* update debian/changelog from TODO-RELEASE
* cleanup TODO-RELEASE
For non-library projects:
* update debian/changelog from git log
Note: it requires bumpversion package to be installed, debian/control is
adjusted accordingly. The helper itself is installed to facilitate reuse
by other libraries.
N. B: you still have to manually adjust LIBVERSION in previous commit -
see TODO-RELEASE header for details.
Use it as follows:
make REL=minor release
The REL parameter defines which component of the version [1] to bump and
can be any of { major, minor, patch }.

In tightly embedded builds (--enable-embedded), we want the ability to
replace talloc with a very simple heap allocator to avoid the complexity
of talloc without modifying all our code that assumes talloc.
This will break the hierarchical notion of the allocator, but
libosmo{core,gsm,coding,codec} don't rely on that anyway.

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

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.

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

Numerous issues caused sim_test to be attempted even though libosmosim was not
built:
In configure.ac, the ENABLE_PCSC variable lacked an AC_SUBST() to be exported.
Furthermore in configure.ac, no value 'yes'/'no' was assigned to the
ENABLE_PCSC variable, only to the enable_pcsc value.
In testsuite.at, encapsulating the sim_test in 'if ENABLE_PCSC' seems to have
no effect, regardless (not even when using a variable that should be defined
accurately).
So fix with these steps, similarly to how we do it in openbsc:
In AC_ARG_ENABLE, directly use 'ENABLE_PCSC' to assign 'yes'/'no'.
Export the same using AC_SUBST().
Add tests/atlocal.in to translate ENABLE_PCSC to enable_sim_test (also add
atlocal to AC_OUTPUT and distclean).
Use enable_sim_test in testuite.at, as seen in openbsc: use AT_CHECK() to
indicate skipping the test if enable_sim_test isn't 'yes'.

--enable-sanitize adds address sanitizer CFLAGS/CPPFLAGS to the entire build.
Also pass UBSAN_OPTIONS to the test suite run (only has effect during runtime).
Add this flag to jenkins.sh's configure step. To ensure that we get the
sanitize results, add 'make check' to jenkins to catch sanitize failures;
Keep 'make distcheck' without ASAN; it has its own configure which omits
--enable-sanitize. This way we test both with and without ASAN.

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.

As we are making a decision whether we should use an existing system
library, we call it --with-system-talloc, rather than
--enable-system-talloc.

This introduces a new configure flag by which the libosmocore-internal
talloc code is not compiled, but rather a system-wide libtalloc is used.
When we started openbsc/libosmocore in 2008, libtalloc was not widely
present on systems yet. This has changed meanwhile, and we should
simply use the system-wide library

|
When using configure --disable-static, no libosmogsm.a will be
created, and the tests fail to link because symbols like _a5_3 and
_a5_4 are not exported through the only remaining libosmogsm.so.
A method to overcome this is an intermediate private non-distributed
library, examples of which are present in e.g. libabc, kmod and
systemd.
With this, disable-static can now be the default and practical compile
time be halved.
