565e4993c6 lavfi: merge start_frame/draw_slice/end_frame 
Any alleged performance benefits gained from the split are purely
mythological and do not justify added code complexity.

bb6c67bb36 lavfi: remove vf_slicify 
The following commit will make it useless.

The crop_scale_vflip FATE test changes because of off-by-one differences
in output when vflipped slices are passed to sws.

480178a295 x86: yadif: fix asm with suncc 
Under some circumstances, suncc will use a single register for the
address of all memory operands, inserting lea instructions loading
the correct address prior to each memory operand being used in the
code. In the yadif code, the branch in the asm block bypasses such
an lea instruction, causing an incorrect address to be used in the
following load.

This patch replaces the tmpX arrays with a single array and uses a
register operand to hold its address. Although this prevents using
offsets from the stack pointer to access these locations, the code
still builds as 32-bit PIC even with old compilers.

239fdf1b4a x86: build: replace mmx2 by mmxext 
Refactoring mmx2/mmxext YASM code with cpuflags will force renames.
So switching to a consistent naming scheme beforehand is sensible.
The name "mmxext" is more official and widespread and also the name
of the CPU flag, as reported e.g. by the Linux kernel.

b7558ac293 af_amix: avoid spurious EAGAIN. 
Input on/off state can change in request_samples(), which can result in
a state where only the first input is active. get_available_samples()
will then return 0, and request_frame() will fail with EAGAIN even
though there is data on the single active input.

Take this into account and check the number of active inputs again after
calling request_samples().

7c29377b70 lavfi: reclassify showfiltfmts as a TESTPROG 
This tool uses lavfi internal symbols not accessible in shared
libraries.  TESTPROGS are linked statically to allow them use of
library internals not normally exported.

fa06623930 lavfi/audio: eliminate ff_default_filter_samples(). 
It currently does the following:
1) get a zeroed audio buffer
2) copy some properties (but not the data) of the input buffer to it
3) pass this buffer to the output filter
This looks useless and is indeed not used by any filters, therefore
delete it.

Make ff_null_filter_samples() (just pass the buffer to the next filter)
the new default.

e026c9b390 lavfi/audio: don't set cur_buf in ff_filter_samples(). 
It's redundant, since the input buffer is passed as a parameter to the

the link.
