ffba2053ed lavfi: fix compatibility code for old vf_scale options syntax 
Currently it would incorrectly trigger on a string that contains a '='
but does not contain a ':', e.g. flags=<flags>.

096696ef0d avfiltergraph: simplify inserting conversion filters. 
There is now no need to explicitly pass 0:0 as width/height to scale,
those are the defaults.

d10499a32a yadif: correct strides in filter_edges_16bit 
The C code treats the data as arrays of uint16_t so strides must not
be in bytes but in pixels.

b0ef0ae776 yadif: restore speed of the C filtering code 
Always use the special filter for the first and last 3 columns (only).

Changes made in 64ed397 slowed the filter to just under 3/4 of what it
was.  This commit restores the speed while maintaining identical output.

For reference, on my Athlon64:

2358563 decicycles in new
1727558 decicycles in this

16a4a18db0 af_asyncts: fix offset calculation 
delta is in samples, not bytes. Also the sample format is not guaranteed
to be planar.

20c86571cc lavfi: let gcc realign the stack on public graph driving functions 
The functions which actually drive the filter graph by pushing
frames through it need to ensure an aligned stack for SIMD functions.

This fixes a crash in YADIF filter when using a mingw build in a MSVC
application.

9bfc6e02ba afifo: fix request_samples on the last frame in certain cases 
The current code can fail to return the last frame if it contains
exactly the requested number of samples.

Fixes the join filter test, which previously did not include the last
408 samples in most cases.

c2c9801bc9 lavfi: deprecate avfilter_graph_add_filter(). 
Since this function adds a standalone filter to a filter graph and we do
not support creating such filters, there is no reason for this function
to exist.

bc1a985ba0 lavfi: replace avfilter_open() with avfilter_graph_alloc_filter(). 
Since we do not support "standalone" filters not attached to an
AVFilterGraph, we should not have a public function to create such
filters. In addition that function is horribly named, the action it does
cannot be possibly described as "opening" a filter.

38f0c0781a lavfi: merge avfiltergraph.h into avfilter.h
