There are lots of files that don't need it: The number of object
files that actually need it went down from 2011 to 884 here.
Keep it for external users in order to not cause breakages.
Also improve the other headers a bit while just at it.

Makes it robust against adding fields before it, which will be useful in
following commits.
Majority of the patch generated by the following Coccinelle script:
@@
typedef AVOption;
identifier arr_name;
initializer list il;
initializer list[8] il1;
expression tail;
@@
AVOption arr_name[] = { il, { il1,
- tail
+ .unit = tail
}, ... };
with some manual changes, as the script:
* has trouble with options defined inside macros
* sometimes does not handle options under an #else branch
* sometimes swallows whitespace
Unnecessary since acf63d5350;
also avoids relocations.

This should hopefully clarify that the option only affects MSZ
full-width characters, and not all full-width ASCII. Additionally,
this matches the prefix with the upstream option.

This patch adds two MSZ (Middle Size; half width) character
related options, mapping against newly added upstream
functionality:
* `replace_msz_japanese`, which was introduced in version 1.0.1
of libaribcaption.
* `replace_msz_glyph`, which was introduced in version 1.1.0
of libaribcaption.
The latter option improves bitmap type rendering if specified
fonts contain half-width glyphs (e.g., BIZ UDGothic), even
if both ASCII and Japanese MSZ replacement options are set
to false.
As these options require newer versions of libaribcaption, the
configure requirement has been bumped accordingly.

On some environments, a `bool` variable is of smaller size than `int`.
As AV_OPT_TYPE_BOOL is internally handled as sizeof(int), if a `bool`
option was set on such an environment, the memory of following
variables would be filled. Additionally, set values may be destroyed
by av_opt_copy().

These defines are also used in other contexts than just AVCodecContext
ones, e.g. in libavformat. Furthermore, given that these defines are
public, the AV-prefix is the right one, so deprecate (and not just move)
the FF-macros.

This patch add another ARIB caption decoder using libaribcaption
external library.
Unlike libaribb24, it supports 3 types of subtitle outputs:
* text: plain text
* ass: ASS formatted text
* bitmap: bitmap image
Default subtitle type is ass as same as libaribb24.
Advantages compared with libaribb24 on ASS subtitle are:
* Subtitle positioning.
* Multi-rect subtitle: some captions are displayed at different
position at a time.
* More stability and reproducibility.
To compile with this feature:
* libaribcaption external library has to be pre-installed.
https://github.com/xqq/libaribcaption
* configure with `--enable-libaribcaption` option.
`--enable-libaribb24` and `--enable-libaribcaption` options are
not exclusive. If both enabled, libaribcaption precedes as
order listed in `libavcodec/allcodecs.c`.
