lavfi: add query_func2()
...
It differs from query_func() in accepting arrays of input/output format
configurations to be filled as callback parameters. This allows to mark
the filter context as const, ensuring it is not modified by this
function, as it is not supposed to have any side effects beyond
returning the supported formats.

Move them there and remove internal.h

lavfi/internal: move functions used by filters to filters.h
...
internal.h currently mixes interfaces intended to be used by filters
with those that should be limited to generic filter- or graph-level
code.

lavfi: add a new struct for private link properties
...
Specifically those that should be visible to filters, but hidden from
API callers. Such properties are currently located at the end of the
public AVFilterLink struct, demarcated by a comment marking them as
private. However it is generally better to hide them explicitly, using
the same pattern already employed in avformat or avcodec.
The new struct is currently trivial, but will become more useful in
following commits.

These wrappers cost nothing, they make the namespace more
consistent and they will be useful if/when locking becomes
necessary.

Unlike av_frame_is_writable(), it uses the link's alloc callback,
making direct rendering possible.
The code comes from ff_filter_frame_framed(), moved with mostly
trivial changes.
