116cb346e3 vulkan_h264: fix long-term ref handling
h->long_ref isn't guaranteed to be contiguously filled. Use the approach
from both vaapi_h264 and vdpau_h264 which goes through the 16 frames in
h->long_ref to find the LTR entries.

Fixes MR2_MW_A.264 from JVT-AVC_V1.

1cff6e41bf lavc/libaribcaption: rename replace_fullwidth_ascii to replace_msz_ascii
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.

8ccd1593a4 lavc/libaribcaption: add MSZ character related options
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.

48afb43549 lavc/libaribcaption: switch all bool context variables to int
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().

Only the collocated_ref of the current frame (i.e. HEVCContext.ref)
is ever used*, so move it to HEVCContext directly after ref.

*: This goes so far that collocated_ref was not even synced across
threads in case of frame-threading.

vulkan_decode: use coded_width/height instead of the non-coded width and height
Partially fixes https://streams.videolan.org/issues/19938/20000_20180305-15.04.59.ts
The is coded as 1920x1080, meant to be rendered at 1440x1080 with cropping,
or 1680x1080 before cropping. Currently, the created DPB is 1440x1080, which results
in the image being decoded incorrectly, as the decoder overwrites output memory.
This commit fixes this.

315c956cbd avcodec/pthread_frame: Remove ff_thread_release_buffer()
It is unnecessary since the removal of non-thread-safe callbacks
in e0786a8eeb. Since then, the
AVCodecContext has only been used as logcontext.

Removing ff_thread_release_buffer() allowed to remove AVCodecContext*
parameters from several other functions (not only unref functions,
but also e.g. ff_h264_ref_picture() which calls ff_h264_unref_picture()
on error).

avcodec/librsvgdec: fix memory leaks and deprecated functions
At various points through the function librsvg_decode_frame, errors are
returned from immediately without deallocating any allocated structs.
This patch both fixes those leaks, and also fixes the use of functions
that are deprecated since librsvg version 2.52.0. The older calls are
still used, guarded by #ifdefs while the newer replacements are used if
librsvg >= 2.52.0. One of the deprecated functions is used as a check
for the configure shell script, so it was replaced with a different
function.
