Just like the sidechaingate filter, the sidechaincompress filter
overwrote the channel layout and channel count of its output in
its config_output callback to match the channel layout of its main
input instead of linking the main input and its output together
in its query_formats callback.
This is an API violation that can lead to segfaults, as in the
following filtergraph, where stereotools rightly expects stereo,
yet receives only mono:
[in]aformat=channel_layouts=mono,aformat=channel_layouts=stereo|mono[out];\
[out][in2]sidechaincompress,stereotools
Fix this by linking the channel layouts of the main input and the output
in query_formats and remove the code overwriting it in config_output.

The sidechaingate filter wants its main input and its (only) output
to have the same channel layout and number of channels; yet it does
not link them in its query_formats callback. Instead it sets the
outlink to only accept the first offered choice for the main input's
channel layout and then sets both inputs to independently accept
any channel counts. The config_output callback then overwrote the
outlink's channel layout and channels properties with the main input's,
even though they may differ in case the first offered choice for
the main input's channel layout turns out not to be the final one.
Consider e.g. the following filtergraph:
[in]aformat=channel_layouts=mono,aformat=channel_layouts=stereo|mono[out];\
[out][in2]sidechaingate,stereotools
The two aformats ensure that the first offered channel layout (stereo)
will not be chosen for the input; yet it is the only offered channel
layout for the output of sidechaingate and will therefore be chosen
by the query_formats framework. Because the sidechaingate outputs
interleaved doubles which stereotools expects the output of
sidechaingate appears to be suitable as input for stereotools without
further conversions. Yet stereotools actually only receives a mono frame
and therefore overreads its input buffer which leads to segfaults;
it can also lead to heap corruption because there can be writes beyond
the end of the buffer, too.
Fix this by linking the channel layouts of the main input and the output
in query_formats and remove the code overwriting it in config_output.

By using preinit, the AVDCT already exists directly after
allocating the filter, so that the filter's AVClass's child_next
becomes usable for setting options with the AV_OPT_SEARCH_CHILDREN
search flag. This means that it is no longer necessary to use
the init_dict callback for this filter.
Furthermore, the earlier code did not abide by the documentation
of the init_dict callback at all: Instead of only returning the
options that have not been recognized it always returned all options
on any av_opt_set() error and errored out in this case, even if it
is just an unrecognized option. This behaviour has been inherited by
avfilter_init_dict(), contradicting its documentation. This is also
fixed in this commit.

We introduced a ff_horiz_slice_avx2/512() implemented on a new algorithm.
In a nutshell, the new algorithm does three things, gathering data from
8/16 rows, blurring data, and scattering data back to the image buffer.
Here we used a customized transpose 8x8/16x16 to avoid the huge overhead
brought by gather and scatter instructions, which is dependent on the
temporary buffer called localbuf added newly.
Performance data:
ff_horiz_slice_avx2(old): 109.89
ff_horiz_slice_avx2(new): 666.67
ff_horiz_slice_avx512: 1000

Now the user can switch between async and sync mode by using the
'async' option in the backend_configs. The values can be 1 for
async and 0 for sync mode of execution.

2. vf_dnn_detect

Up until now, an AVFilter's lists of input and output AVFilterPads
were terminated by a sentinel and the only way to get the length
of these lists was by using avfilter_pad_count(). This has two
drawbacks: first, sizeof(AVFilterPad) is not negligible
(i.e. 64B on 64bit systems); second, getting the size involves
a function call instead of just reading the data.
This commit therefore changes this. The sentinels are removed and new
private fields nb_inputs and nb_outputs are added to AVFilter that
contain the number of elements of the respective AVFilterPad array.
Given that AVFilter.(in|out)puts are the only arrays of zero-terminated
AVFilterPads an API user has access to (AVFilterContext.(in|out)put_pads
are not zero-terminated and they already have a size field) the argument
to avfilter_pad_count() is always one of these lists, so it just has to
find the filter the list belongs to and read said number. This is slower
than before, but a replacement function that just reads the internal numbers
that users are expected to switch to will be added soon; and furthermore,
avfilter_pad_count() is probably never called in hot loops anyway.
This saves about 49KiB from the binary; notice that these sentinels are
not in .bss despite being zeroed: they are in .data.rel.ro due to the
non-sentinels.
