tests: add format / codec transcoding tests

This test group is intended to check the format / codec transcoding capabilities of the library. The reference files are used to ensure that encoding or decoding was successful.

The following formats are currently being tested:

- amr_efr - gsm - racal_hr - racal_fr - racal_efr - ti_hr - ti_fr - ti_efr - rtp_efr - rtp_hr_etsi - rtp_hr_ietf

osmo-gapk: fix I/O count check condition

The stdin / stdout operation was broken by a new check condition, introduced by the 15fa605576a81803c57a144231e9e9720aa133a1.

tests: add pq_rtp test

This test is intended to check the RTP source / sink operability. To do this, two processing queues are being allocated:

"generator": source/random -> sink/rtp "checker": source/rtp -> sink/checker

The first one generates some amount of random bytes (payload), and stores them inside a buffer that is shared between both queues.

After generation, a payload is being sent from the first queue via an RTP sink, and then being received by the second via an RTP source.

As both queues do use a shared buffer, the last item of the second queue (named 'sink/checker') is able to compare a received payload with expected.

tests: add pq_file test

This test is intended to check the file source / sink operability. To do that, the following processing chain is being composed:

source/file -> proc/dummy -> sink/file (stdout)

The source item opens the sample file named 'io_sample.txt' for reading. The next processing item simply converts all uppercase latters to the lowercase. The last one writes the result to stdout.

This processing cycle is being repeated several times with different block length values.

tests: add procqueue test

This test is intended to validate the processing queue management API. Moreover, the talloc debugging API is used to ensure that there are no memory leaks.

First, four processing queues are being allocated. One of them is empty, while others have different count of items. Then the human-readable description is being generated for all of them. And finally, the processing and exit cllback are being tested.

During the test execution, the talloc NULL-context tracking feature is enabled, allowing to observe every memory allocation within the libosmogapk, and to detect memory leaks.

procqueue: allocate an output buffer as named chunk

The talloc_size() call sets the current file name and the current line number as name for chunk being allocated. This combination is not so informative during debugging, so let's use the static '.buffer' string as context name for item's output buffer.

procqueue: separate queue check function

In order to give advanced control over a processing queue, it would be better to have the checking function separated from the osmo_gapk_pq_prepare(). Moreover, this change introduces an additional 'strict' checking mode that requires a queue to have a source item first and a sink item in the last position.

procqueue: add item type enum (source, sink, proc)

There are currently three types of prcessing queue items:

- source (file, alsa, rtp) - proc (format, codec) - sink (file, alsa, rtp)

Let's assign corresponding type for each item. This would facilitate logging and the queue checking.

libosmogapk: drop an 'osmo' prefix from internal log variables

src/pq_alsa.c: implement processing state callback

procqueue: add processing state callback

In some cases it's required to wait for some queue items to finish processing. For example, the ALSA sink writes the audio samples to the buffer in non-blocking mode, so as soon as all of them will be written, a program may finish execution, causing the playback abort.

To prevent that, this change extends the library's API, allowing each queue item to have a processing state callback that returns a positive integer if processing is not finished yet, and 0 otherwise.

libosmogapk: use Osmocom logging framework

benchmark: allocate memory dynamically

Having statically allocated memory for benchmark data of every codec causes high memory usage, especially if actual benchmarking is not required for a particular use case. Instead of that, let's provide an optional opportunity to enable benchmarking for a particular codec by calling the osmo_gapk_bench_enable(). The required amount of memory would be allocated, and then can be freed by calling the osmo_gapk_bench_free() or manually.

Add an 'osmo_gapk' prefix to the exposed symbols

To avoid a naming conflict between libosmogapk and other projects during linkage, all the exposed symbols should have an unique prefix. Let's use 'osmo_gapk' for that.

procqueue: expose the processing queue struct definition

To be able to use processing queues from outside, the pq struct should be shared in the corresponding header file.

Add a pkg-config manifest for libosmogapk

In order to make pkg-config 'see' the libosmogapk, a corresponding package description is required. For more details, see:

Use '#pragma once' instead of include guard

The most compilers today do support the '#pragma once', which is designed to cause the current source file to be included only once in a single compilation. One has several advantages, including: less code, avoidance of name clashes, and sometimes improvement in compilation speed.

See: https://en.wikipedia.org/wiki/Pragma_once for details.

Install GAPK headers to '${includedir}/osmocom/gapk/'

To be able to use the library, external applications need to know, which symbols are exposed. This information is provided by header files, which are being installed to a system's ${includedir} since this change.

Add an 'osmo' prefix to the 'gapk' binary

This is a common practice of all Osmocom executables to have an 'osmo' prefix. Let's follow this here too.

Introduce a shared 'libosmogapk' library

The previous GAPK implementation was represented as a single executable. So, all audio transcoding operations were available only by calling the 'gapk' binary. This approach didn't allow external applications to benefit from using GAPK API directly.

Since there are some projects (such as GR-GSM and OsmocomBB), which are potential users of GAPK code base, it would be better to have all transcoding functions within a shared library.

So, this change separates the common code into a shared library, named 'libosmogapk', and links the 'gapk' binary against one. Currently there are no shared headers, pkg-config manifest and the export map, but they will be done latter.
