 *
 * Output file/data format handling.
 *
 * libsigrok supports several output (file) formats, e.g. binary, VCD,
 * gnuplot, and so on. It provides an output API that frontends can use.
 * New output formats can be added/implemented in libsigrok without having
 * to change the frontends at all.
 *
 * All output modules are fed data in a stream. Devices that can stream data
 * into libsigrok live, instead of storing and then transferring the whole
 * buffer, can thus generate output live.
 *
 * Output modules are responsible for allocating enough memory to store
 * their own output, and passing a pointer to that memory (and length) of
 * the allocated memory back to the caller. The caller is then expected to
 * free this memory when finished with it.
