The `-caption_encoding` option was reported as having a default value of
'ass', whereas it's actually 'auto'.

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.

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`.

Max region ID is 87. Also the region affects not only the G0 charset but G2 and
the national subset as well.

Disable by default to output all the layers, to match libaomdec wrapper.
Add option to select the operating point for the spatial layers.
Update the documentation with the new options.

* Outputs ASS lines with basic coloring and font scaling for each
given region.
* Sets the default style to the resolution of the subtitle plane
(for example, 960x540 / 36pt font for profile A).
* Has options to:
* Disable ruby text (which is coded as regions which have
half-height text in libaribb24).
Enabled by default as without positioning ruby text only
confuses as it is usually coded in the beginning of the decoded
subtitle line.
* Set the working directory, in which libaribb24 will read
configuration as well as into which it may save broadcast extra
symbols as PNG.
Unset by default.
The unconventional library check can be explained by the library's
current master branch being licensed as LGPLv3, but at the time of
writing the latest official release is still licensed under GPLv3.
Thus, one either has to wait for the following release, or enable
GPLv3.
Most decoders (pgssubdec, ccaption_dec) are using -1 or UINT32_MAX for a
subtitle event which should be cleared at the next event.
