These checks emit warnings in case the channel layouts lists are
inconsistent; yet since 69f5f6ea37
a function that is called earlier errors out if they are inconsistent.

This currently happens by accident in a few filters that use
ff_set_common_(samplerates|channel_layouts) like afir (if the response
option is set) or agraphmonitor (due to the default code in
avfiltergraph.c). So change those functions to make sure it does no
longer happen.

The ff_set_common_(formats|channel_layouts|samplerates) have to free
their list in case it doesn't have an owner; therefore they tracked
whether they attached it to an owner. But the list's refcount already
contains such a counter, so we don't have to keep track of whether we
have attached the list to an owner.

It is unnecessary as the number of static inputs and outputs can now
be directly read via AVFilter.nb_(in|out)puts.

It is intended as replacement for avfilter_pad_count(). In contrast to
the latter, it avoids a loop.

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.

These fields are mutually exclusive, so putting them in a union
is possible and makes AVFilterPad smaller.
