The windows SDL audio driver plays the old data in the buffer in a loop if it
is not updated in time. So instead of waiting for data and blocking the the
audio thread, return silence if no data is available.

Should fix ticket #2289.

Github: Closes #143

Fixes auto-detection of compressed swf files as in
http://samples.ffmpeg.org/SWF/compressed-swf/
Reported by forum user Zard1096.

The .text section is already 16-byte aligned by default on all supported
platforms so `SECTION_TEXT` isn't any different from `SECTION .text`.

Change ALLOC_STACK to always align the stack before allocating stack space for
consistency. Previously alignment would occur either before or after allocating
stack space depending on whether manual alignment was required or not.

The FILE struct is opaque in MSVC 2015, and the members of this struct
were never meant to be accessed in any case.

No conditions are known where this check was needed to get characters
from stdin.

Mixing stdio and low-level IO on stdin is not safe.

This is the same fix that Hendrik made to dxva2_hevc. It should be
equally required here, although I don't see any visual difference.
Nevertheless, best to stay consistent.

The latest nvidia 355.06 drivers fixes the interleaving bug when
video surfaces are rendered. It still seems to be broken for
read-back with getBits but that's sufficiently uninteresting that
I don't think we need to wait for it to remove the flag.

According to S377M, segmented frame layout is identical to separate
field layout except that the two fields are taken from a single scan
of the incoming image, ie: they are coincident in time. Thus the
resulting frame is progressive.

On Xcode's clang on OS X, $cc --version will output a 'Configured with:'
line to stderr, which clobbers the configure script output. As this line
serves no further purpose, it should be silenced.

The same applies to apple-gcc 4.2.1, which complains that it can not
understand the kernel version it is running on.

Only two functions that use xop multiply-accumulate instructions where the

ucNumDeltaPocsOfRefRpsIdx needs to contain the flat value from the SPS RPS,
and not the final computed value from the slice header RPS, as this calculation
is done internally by the driver again.
