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.
