We deliberately do not include these files in the git repository,
nor do we intend to include them in the release tarballs. This
is done intentionally to avoid potential licensing issues.

[this fix already exists in most of the other repos]
As pointed out at https://github.com/libexpat/libexpat/issues/312
libtool does not play nice with clang sanitizer builds at all.
For those builds LD shoud be set to clang too (and LDFLAGS needs the
sanitizer flags as well), because the clang compiler driver knows how
linking to the sanitizer libs works, but then at a later stage libtool
fails to actually produce the shared libraries and the build fails. This
is fixed by this patch.
Addtionally LD_LIBRARY_PATH has no effect on conftest runs during
configure time, so the rpath needs to be set to the asan library path to
ensure the configure run does not fail due to a missing asan library,
i.e.:
SANS='-fsanitize=memory -fsanitize-recover=all -shared-libsan'
export CC=clang-10
ASANPATH=$(dirname `$CC -print-file-name=libclang_rt.asan-x86_64.so`)
export LDFLAGS="-Wl,-rpath,$ASANPATH $SANS $LDFLAGS"

In change [1] I moved libraries from _LDFLAGS to _LIBADD, but I did
not notice that there was another problem: when building with gsmhr,
the content of _LIBADD gets overwritten in a conditional block.
Do not overwrite but append libgsmhr.la to _LIBADD.

This option should be used for any executables which are used only
for testing, or for generating other files and are consequently never
installed. By specifying this option, we are telling Libtool that
the executable it links will only ever be executed from where it is
built in the build tree. Libtool is usually able to considerably
speed up the link process for such executables.

When throttling is enabled, one voice frame will be processed every
20ms. This is useful for e.g. playback of a file as a RTP stream.
Without this option, the entire file would generate a flood of RTP
messages, rather than a continuous stream.

For a long time the RTP payload type was hard-coded for outgoing
frames. The problem is that according to RFC 3551 only GSM FR has
a static payload type value (see table 4, value 3). For other
codecs the payload type may be negotiated between the both
sides dynamically (i.e. in range 96-127).
Let's allow a binary/API user to configure this manually.

The 'distcheck' rule performs all of the operations associated with

There were several problems:

At the moment, Half Rate codec support is limited. There are still
some issues with encoding of the reference files (see OS#2514),
and moreover AddressSanitizer is not happy about libgsmhr...

Despite it was stated that only the last nibble isn't being
written, some other bytes in the middle of the output buffer
were uninitialized during the first exectution of a queue.
The problem was observed with AddressSanitizer enabled.

The talloc_enable_null_tracking() actually allocates a new talloc
context, which makes both Valgrind and LeakSanitizer angry. This
context should be freed by the talloc_disable_null_tracking().

This change fixes parallel building problem, when osmo-gapk was
being compiled before its libosmogapk dependency:
make[2]: *** No rule to make target '../src/libosmogapk.la',
needed by 'osmo-gapk'. Stop.
make[2]: *** Waiting for unfinished jobs....
For some reason, automake ignores a dependency if the full
path is provided:
$(top_builddir)/src/libosmogapk.la
while the relative path solves the problem:
libosmogapk.la

The previous GAPK implementation was represented by a single
executable. So, all audio transcoding operations were available
only via calling the 'gapk' binary. This approach didn't allow
external applications to benefit from using GAPK API directly.
The following set of changes separates the common code into a
shared library called 'libosmogapk', linking the 'gapk' binary
against it:
- 95e6664 Introduce a shared 'libosmogapk' library
- 30209ce Install GAPK headers to '${includedir}/osmocom/gapk/'
- a8d4657 Add an 'osmo_gapk' prefix to the exposed symbols
- 40d59f1 Add a pkg-config manifest for libosmogapk
- 4f0a47d Add the symbol export map for libosmogapk
All memory management operations are now based on talloc library:
- 3c20dac libosmogapk: use talloc for memory management
- 5cabe1e osmo-gapk: use talloc for memory management
Integrated Osmocom logging framework:
- c35ba8a libosmogapk: use Osmocom logging framework
- 4b7cd2c osmo-gapk: drop useless printf calls
- 0fe18af osmo-gapk: use Osmocom logging framework
- 11943bf osmo-gapk: adjust application verbosity
Integrated GNU Autotest environment and basic test coverage:
- f069eb3 Init automake test environment
- 1fe6a9b tests: add procqueue test
- 3e9e57f tests: add pq_file test
- 9d2b15d tests: add pq_rtp test
- f59f3f1 tests: add format / codec transcoding tests
