libav/ffmpeg: Move current lavc53.lavf53.lavu51 (version 8) header files to their sub-folders; Add lavc54.lavf54.lavu52 (version 9) header files

lavc54.lavf54.lavu52:
  - Begin testing w/ version 9
  - Header files are binary incompatible (data types)

Default is still lavc53.lavf53.lavu51

- * @defgroup avoptions AVOptions
- * @ingroup lavu_data
- * @{
- * AVOptions provide a generic system to declare options on arbitrary structs
- * ("objects"). An option can have a help text, a type and a range of possible
- * values. Options may then be enumerated, read and written to.
- *
- * @section avoptions_implement Implementing AVOptions
- * This section describes how to add AVOptions capabilities to a struct.
- *
- * All AVOptions-related information is stored in an AVClass. Therefore
- * the first member of the struct must be a pointer to an AVClass describing it.
- * The option field of the AVClass must be set to a NULL-terminated static array
- * of AVOptions. Each AVOption must have a non-empty name, a type, a default
- * value and for number-type AVOptions also a range of allowed values. It must
- * also declare an offset in bytes from the start of the struct, where the field
- * associated with this AVOption is located. Other fields in the AVOption struct
- * should also be set when applicable, but are not required.
- *
- * The following example illustrates an AVOptions-enabled struct:
- * @code
- * typedef struct test_struct {
- *     AVClass *class;
- *     int      int_opt;
- *     char    *str_opt;
- *     uint8_t *bin_opt;
- *     int      bin_len;
- * } test_struct;
- *
- * static const AVOption options[] = {
- *   { "test_int", "This is a test option of int type.", offsetof(test_struct, int_opt),
- *     AV_OPT_TYPE_INT, { -1 }, INT_MIN, INT_MAX },
- *   { "test_str", "This is a test option of string type.", offsetof(test_struct, str_opt),
- *     AV_OPT_TYPE_STRING },
- *   { "test_bin", "This is a test option of binary type.", offsetof(test_struct, bin_opt),
- *     AV_OPT_TYPE_BINARY },
- *   { NULL },
- * };
- *
- * static const AVClass test_class = {
- *     .class_name = "test class",
- *     .item_name  = av_default_item_name,
- *     .option     = options,
- *     .version    = LIBAVUTIL_VERSION_INT,
- * };
- * @endcode
- *
- * Next, when allocating your struct, you must ensure that the AVClass pointer
- * is set to the correct value. Then, av_opt_set_defaults() must be called to
- * initialize defaults. After that the struct is ready to be used with the
- * AVOptions API.
- *
- * When cleaning up, you may use the av_opt_free() function to automatically
- * free all the allocated string and binary options.
- *
- * Continuing with the above example:
- *
- * @code
- * test_struct *alloc_test_struct(void)
- * {
- *     test_struct *ret = av_malloc(sizeof(*ret));
- *     ret->class = &test_class;
- *     av_opt_set_defaults(ret);
- *     return ret;
- * }
- * void free_test_struct(test_struct **foo)
- * {
- *     av_opt_free(*foo);
- *     av_freep(foo);
- * }
- * @endcode
- *
- * @subsection avoptions_implement_nesting Nesting
- *      It may happen that an AVOptions-enabled struct contains another
- *      AVOptions-enabled struct as a member (e.g. AVCodecContext in
- *      libavcodec exports generic options, while its priv_data field exports
- *      codec-specific options). In such a case, it is possible to set up the
- *      parent struct to export a child's options. To do that, simply
- *      implement AVClass.child_next() and AVClass.child_class_next() in the
- *      parent struct's AVClass.
- *      Assuming that the test_struct from above now also contains a
- *      child_struct field:
- *
- *      @code
- *      typedef struct child_struct {
- *          AVClass *class;
- *          int flags_opt;
- *      } child_struct;
- *      static const AVOption child_opts[] = {
- *          { "test_flags", "This is a test option of flags type.",
- *            offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { 0 }, INT_MIN, INT_MAX },
- *          { NULL },
- *      };
- *      static const AVClass child_class = {
- *          .class_name = "child class",
- *          .item_name  = av_default_item_name,
- *          .option     = child_opts,
- *          .version    = LIBAVUTIL_VERSION_INT,
- *      };
- *
- *      void *child_next(void *obj, void *prev)
- *      {
- *          test_struct *t = obj;
- *          if (!prev && t->child_struct)
- *              return t->child_struct;
- *          return NULL
- *      }
- *      const AVClass child_class_next(const AVClass *prev)
- *      {
- *          return prev ? NULL : &child_class;
- *      }
- *      @endcode
- *      Putting child_next() and child_class_next() as defined above into
- *      test_class will now make child_struct's options accessible through
- *      test_struct (again, proper setup as described above needs to be done on
- *      child_struct right after it is created).
- *
- *      From the above example it might not be clear why both child_next()
- *      and child_class_next() are needed. The distinction is that child_next()
- *      iterates over actually existing objects, while child_class_next()
- *      iterates over all possible child classes. E.g. if an AVCodecContext
- *      was initialized to use a codec which has private options, then its
- *      child_next() will return AVCodecContext.priv_data and finish
- *      iterating. OTOH child_class_next() on AVCodecContext.av_class will
- *      iterate over all available codecs with private options.
- *
- * @subsection avoptions_implement_named_constants Named constants
- *      It is possible to create named constants for options. Simply set the unit
- *      field of the option the constants should apply to to a string and
- *      create the constants themselves as options of type AV_OPT_TYPE_CONST
- *      with their unit field set to the same string.
- *      Their default_val field should contain the value of the named
- *      constant.
- *      For example, to add some named constants for the test_flags option
- *      above, put the following into the child_opts array:
- *      @code
- *      { "test_flags", "This is a test option of flags type.",
- *        offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { 0 }, INT_MIN, INT_MAX, "test_unit" },
- *      { "flag1", "This is a flag with value 16", 0, AV_OPT_TYPE_CONST, { 16 }, 0, 0, "test_unit" },
- *      @endcode
- *
- * @section avoptions_use Using AVOptions
- * This section deals with accessing options in an AVOptions-enabled struct.
- * Such structs in Libav are e.g. AVCodecContext in libavcodec or
- * AVFormatContext in libavformat.
- *
- * @subsection avoptions_use_examine Examining AVOptions
- * The basic functions for examining options are av_opt_next(), which iterates
- * over all options defined for one object, and av_opt_find(), which searches
- * for an option with the given name.
- *
- * The situation is more complicated with nesting. An AVOptions-enabled struct
- * may have AVOptions-enabled children. Passing the AV_OPT_SEARCH_CHILDREN flag
- * to av_opt_find() will make the function search children recursively.
- *
- * For enumerating there are basically two cases. The first is when you want to
- * get all options that may potentially exist on the struct and its children
- * (e.g.  when constructing documentation). In that case you should call
- * av_opt_child_class_next() recursively on the parent struct's AVClass.  The
- * second case is when you have an already initialized struct with all its
- * children and you want to get all options that can be actually written or read
- * from it. In that case you should call av_opt_child_next() recursively (and
- * av_opt_next() on each result).
- *
- * @subsection avoptions_use_get_set Reading and writing AVOptions
- * When setting options, you often have a string read directly from the
- * user. In such a case, simply passing it to av_opt_set() is enough. For
- * non-string type options, av_opt_set() will parse the string according to the
- * option type.
- *
- * Similarly av_opt_get() will read any option type and convert it to a string
- * which will be returned. Do not forget that the string is allocated, so you
- * have to free it with av_free().
- *
- * In some cases it may be more convenient to put all options into an
- * AVDictionary and call av_opt_set_dict() on it. A specific case of this
- * are the format/codec open functions in lavf/lavc which take a dictionary
- * filled with option as a parameter. This allows to set some options
- * that cannot be set otherwise, since e.g. the input file format is not known
- * before the file is actually opened.
