Just including icodecapi.h + codecapi.h apparently misses some bits,
that MSVC doesn't complain about, but Clang does. Thus add a missing
header to the custom hacky include path (required for keeping
ICodecAPI visible when building in UWP mode, as it is intended to).

The issue in Windows SDK headers about ICodecAPI availability in
UWP/app mode has been reported upstream at
https://developercommunity.visualstudio.com/content/problem/1037125/icodecapi-not-visible-when-compiling-in-uwp-mode.html,
and later also filed in Feedback Hub (which can't be linked to
externally).

This should significantly improve the performance with certain
filterchains.

Otherwise custom vulkan device contexts won't work.

This allows us to speed up only-uploading or only-downloading use cases.

They're nothing special, and there's no reason they should always use the
default flags.

Some users may need special formats that aren't available when the STORAGE
flag bit is set, which would result in allocations failing.

This was never actually used, likely due to confusion, as the device context
also had one used for uploads and downloads.
Also, since we're only using it for very quick image barriers (which are
practically free on all hardware), use the compute queue instead of the
transfer queue.

If an external pool was provided we skipped all of frames init,
including the exec context.

This commit makes full use of the enabled queues to provide asynchronous
uploads of images (downloads remain synchronous).
For a pure uploading use cases, the performance gains can be significant.

Makes it easier to support multiple queues

Some things like using ImageLists were from a really old version that
still used multiplanar images.

With this, the puzzle of making libplacebo, ffmpeg and any other Vulkan
API users interoperable is complete.
Users of both libraries can initialize one another's contexts without having
to create a new one.

This, along with the next patch, are the last missing pieces to being
interoperable with libplacebo.

This allows for users who derive devices to set options for the
new device context they derive.
The main use case of this is to allow users to enable extensions
(such as surface drawing extensions) in Vulkan while deriving from
the device their frames are on. That way, users don't need to write
any initialization code themselves, since the Vulkan spec invalidates
mixing instances, physical devices and active devices.
Apart from Vulkan, other hwcontexts ignore the opts argument since they
don't support options at all (or in VAAPI and OpenCL's case, options are
currently only used for device selection, which device_derive overrides).

The Xiph foundation never standardized either Daala nor its mapping in Ogg,
and all files that were created are undecodable without knowledge of the
git hash.

Move the contents of all_channel_layouts.inc directly into
libavfilter/tests/formats.c.

The description of AVOutputFormat.init contains the statement that "this
method must not write output". Due to this, the webm_chunk muxer defers
opening the AVIOContext for the child muxer until avformat_write_header(),
i.e. there is no AVIOContext when the sub-muxer's avformat_init_output()
is called. But this violates the documentation of said function which
requires the AVFormatContext to have an already opened AVIOContext.
This commit fixes this.

Don't use the functions for searching substrings when all one is
looking for is a char anyway. Given that there is already a standard
library function for "find last occurence of a char in a string" also
allows one to remove a custom loop.

The current parsing process for adaptation_sets does not guarantee
every adaptation set to contain at least one stream, because the loop
exits immediately as soon as the end of the string has been reached,
without checking whether the currently active adaptation set group is
lacking a stream. This would lead to segfaults lateron as the rest of
the code presumed that every adaptation set contains a stream. This
commit fixes this by erroring out when the last adaptation set group
is incomplete.

The WebM DASH manifest muxer uses a loop to parse the adaptation_sets
string (which is given by the user and governs which AVStreams are
mapped to what adaptation set) and the very beginning of this loop is
"if (*p == ' ') continue;". This of course leads to an infinite loop if
the condition is true. It is true if e.g. the string begins with ' ' or
if there are more than one ' ' between different adaptation set groups.

To fix this, the parsing process has been modified to consume the space
if it is at a place where it can legitimately occur, i.e. when a new
adaptation set group is expected. The latter restriction implies that an
error is returned if a space exists where none is allowed to exist.

The syntax of the adaptation_sets string by which the user determines
the mapping of AVStreams to adaptation sets is
"id=x,streams=a,b,c id=y,streams=d,e" (means: the streams with the
indices a, b and c belong to the adaptation set with id x). Yet there
was no check for whether these indices were actual numbers and if there
is a number whether it really extends to the next ',', ' ' or to the
end of the string or not. This commit adds a check for this.

In order to parse a number from a string, the WebM DASH manifest muxer
would duplicate (via heap-allocation) the part of the string that
contains the number, then read the number via atoi() and then free the
duplicate again. This has been replaced by simply using strtoll() (which
in contrast to atoi() has defined behaviour when the number is not
representable).

Since commit c5324d92 all custom
interleave_packet() functions always return clean packets (even on
error), so that unreferencing manually can be removed.

AVStream.request_probe as well as AVStream.mux_ts_offset are below the
separator of public and private fields, so that a further "NOT PART OF
PUBLIC API" is redundant.
