In order to simplify memory leak debugging, this change introduces
the library's internal talloc context that may be changed by
external application by calling the osmo_gapk_set_talloc_ctx().
There is no need to expose the implementation details of both
BENCHMARK_START and BENCHMARK_STOP macros via public header.
This change moves them to a separate private header 'bench.h'.
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.
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.
While EFR has a canonical format of 31 bytes, the codec_efr.c *does not*
use that canonical format as input. Rather, it uses the format of .amr
files with a 0x3C header as first byte. So the resulting encode/decode
functions should not assume 31 bytes, but 32 bytes.
