e3496e5dbe avfiltergraph: silence an uninitialized variable warning 
The warning is:
libavfilter/avfiltergraph.c: In function ‘avfilter_graph_config’:
libavfilter/avfiltergraph.c:528:9: warning: ‘best_idx’ may be used uninitialized in this function [-Wuninitialized]
libavfilter/avfiltergraph.c:479:13: note: ‘best_idx’ was declared here

Initialize it to an invalid value and add an assert that it's properly
set later.

91a84a5247 af_asyncts: check return value from lavr when flushing. 
Fixes an infinite loop on flush when avresample_get_delay() still
reports some samples but avresample_convert() doesn't return any data.

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.

d1505db067 x86: yadif: Mark mmxext optimizations as such 
The yadif mmx optimizations contain the pmaxsw and pmaxub mmxext
instructions, causing sigills on CPUs that do not support mmxext.

70d71b5801 af_asyncts: add first_pts option 
This allows for padding/trimming at the start of stream. By default, no
assumption is made about the first frame's expected pts, so no padding or
trimming is done.
