a50ccbd240 avutil/tests/lfg.c: added proper normality test 
The Chen-Shapiro(CS) test was used to test normality for
Lagged Fibonacci PRNG.

Normality Hypothesis Test:

The null hypothesis formally tests if the population
the sample represents is normally-distributed. For
CS, when the normality hypothesis is True, the
distribution of QH will have a mean close to 1.

Information on CS can be found here:

dbc932e745 Revert "lavu/atomic: add support for the new memory model aware gcc built-ins" 
This reverts commit faa9d29829.

This change became superfluous when support for C11 atomics was introduced.
Reverting it will make the removal of this implementation in an upcoming
merge conflict free.

a6b1180e39 avcodec/pixlet: fix architecture-dependent code and values 
The constants used in the decoder used floating point precision,
and this caused different values to be generated on different
architectures.

So, eradicate floating point numbers and use fixed point (32.32)
arithmetics everywhere, replacing constants with precomputed integer
values.

b6eaa3928e avcodec/h264, videotoolbox: fix crash after VT decoder fails 
The way videotoolbox hooks in as a hwaccel is pretty hacky. The VT decode
API is not invoked until end_frame(), so alloc_frame() returns a dummy
frame with a 1-byte buffer. When end_frame() is eventually called, the
dummy buffer is replaced with the actual decoded data from
VTDecompressionSessionDecodeFrame().

When the VT decoder fails, the frame returned to the h264 decoder from
alloc_frame() remains invalid and should not be used. Before
9747219958, it was accidentally being
returned all the way up to the API user. After that commit, the dummy
frame was unref'd so the user received an error.

However, since that commit, VT hwaccel failures started causing random
segfaults in the h264 decoder. This happened more often on iOS where the
VT implementation is more likely to throw errors on bitstream anomolies.
A recent report of this issue can be see in
http://ffmpeg.org/pipermail/libav-user/2016-November/009831.html

The issue here is that the dummy frame is still referenced internally by the
h264 decoder, as part of the reflist and cur_pic_ptr. Deallocating the
frame causes assertions like this one to trip later on during decoding:

  Assertion h->cur_pic_ptr->f->buf[0] failed at src/libavcodec/h264_slice.c:1340

With this commit, we leave the dummy 1-byte frame intact, but avoid returning it
to the user.

This reverts commit 9747219958.

a755b725ec avcodec: consider an error during decoder draining as EOF 
There is no reason that draining couldn't return an error or two. But
some decoders don't handle this very well, and might always return an
error. This can lead to API users getting into an infinite loop and
burning CPU, because no progress is made and EOF is never returned.

In fact, ffmpeg.c contains a hack against such a case. It is made
unnecessary with this commit, and removed with the next one. (This
particular error case seems to have been fixed since the hack was
added, though.)

This might lose frames if decoding returns errors during draining.

16abc10b09 ffmpeg: properly cleanup filter graph on init failure 
The filter field is often used to check whether a filter is
configured. If configuring the filter actually fails somewhere in
the middle of it, these fields could still be set to non-NULL, which
lead to other code accessing the half-configured filter graph, which
in turn could lead to crashes within libavfilter.

Solve this by properly resetting all fields.

This was triggered by a fuzzed sample after the recent changes. It's
unknown whether this behavior could be triggered before that.
