We do not support using filters without AVFilterGraph in practice
anyway, so there is no point in pretending we do.

Avoid snprintfing a NULL pointer.

This is more consistent with the naming in the rest of Libav.

Make sure the behavior does not change with the locale.

Prevents it from referring to the rest of the list.

This is required for letting applications to create and destroy
AVFilterInOut structs in a convenient way.

Right now, e.g. scale,[in]overlay would connect scale to the first
overlay input and [in] to the second, which goes against the
documentation and is unintuitive.

The bug happens because of the ordering mess in curr_inputs variable:
1) the unlabeled links from the previous filter are added to it in
correct order
2) input labels are parsed and inserted to the beginning one by one
(i.e. in reverse order)
3) curr_inputs is matched against filter inputs in reverse order

Fix the problem by always using proper ordering without trying to be
clever.

Unlike avfilter_graph_parse(), it returns unlinked inputs and outputs
to the caller, which allows parsing of graphs where inputs/outputs are
not known in advance.

Require "void *" rather than "AVClass *" for the log context type.

Fix crash in create_filter() which occurrs if a scale filter with no
args is provided.

Make avfilter_graph_parse() only release the internal structures
allocated during the parsing, and leave to free the graph itself to
the calling code.

This approach looks cleaner, as the graph is not allocated by the
function.

The new name is shorter and more consistent with the FFmpeg API, and
sounds less evil.

Rename the variable filter to filt_ctx in link_filter_inouts, as the variable denotes a filter context.
