db2733256d pthread_frame: use a thread-safe way for signalling threads to die 
Current code uses a plain int in a racy way, which is UB.

13f5d2bf75 configure: check for stdatomic.h 
Since this is a C11 feature, it requires -std=c11.

Not actually used for anything yet, that will be added in the following
commits.

27085d1b47 avconv: only retry decoding on actual decoding errors 
Errors during decoding are currently considered non-fatal and do not
terminate transcoding, so even if parts of the data are corrupted, the
rest may be decodable.

However, that should apply only to the actual decoding calls, not to the
failures elsewhere (e.g. configuring filters).

f6772e9bf8 avconv: make sure the filtergraph is freed on init failure 
The filtergraph's existence is used in several places to mean that the
filtergraph is fully configured. This causes problems if it's allocated,
but the initialization fails (e.g. if a non-existent filter is
specified).

2124711b95 hwcontext_vaapi: add a quirk for the missing MemoryType attribute 
The Intel binary iHD driver does not support the
VASurfaceAttribMemoryType, so surface allocation will fail when using
it.

b57e38f52c ac3dsp: x86: Replace inline asm for in-decoder downmixing with standalone asm 
Adds a wrapper function for downmixing which detects channel count changes
and updates the selected downmix function accordingly.

43717469f9 ac3dsp: Reverse matrix in/out order in downmix() 
Also use (float **) instead of (float (*)[2]). This matches the matrix
layout in libavresample so we can reuse assembly code between the two.

75c1db6152 avio: cosmetics, prettify AVIO_SEEKABLE_NORMAL 
Move the doxy above the definition, change the value itself to the
(1 << n) pattern, which is more readable for flags.

83548fe894 lavf: fix usage of AVIOContext.seekable 
It is supposed to be a flag. The only currently defined value is
AVIO_SEEKABLE_NORMAL, but other ones may be added in the future.
However all the current lavf code treats this field as a bool (mainly
for historical reasons).
Change all those cases to properly check for AVIO_SEEKABLE_NORMAL.

086e4b58b5 vaapi_encode: Sync to input surface rather than output 
While outwardly bizarre, this change makes the behaviour consistent
with other VAAPI encoders which sync to the encode /input/ picture in
order to wait for /output/ from the encoder.  It is not harmful on
i965 (because synchronisation already happens in vaRenderPicture(),
so it has no effect there), and it allows the encoder to work on
mesa/gallium which assumes this behaviour.

80a5d05108 vaapi_encode: Refactor initialisation

It also commonises some duplicated code around rate control setup
and adds more comments explaining the internals.
