libavcodec/mips: fix for mips optimized fp fft with hard coded tables disabled
Floating point FFT (nips optimized) breaks when hard coded tables are
not enabled because MIPS optimization of floating point FFT uses only
ff_init_ff_cos_tabs(16) which is not enabled by default in that case.
This patch is fixing it.

rtmp: Pass the parameters to do_adobe_auth in the right order
do_adobe_auth takes the parameters in the order "opaque, challenge".
Due to the way they are treated, this didn't matter in the tested
setups though - if both are set, we only use one. In the tested
setups (Wowza and Akamai) either one of them were null or they
were both set to the same value, which is why this worked before.

lavc/utils: add VP6F hack for setting correct video size in stream
For some obscure reasons avcodec_set_dimensions() resets the width/height
so that the resulting value set in the stream is equal to the
corresponding coded_width/height, which is not the same as the correct
width/height in case of the H.264 and VP6F codecs.
This adds a codec-specific hack for VP6F which disables the call to
avcodec_set_dimensions() in avcodec_open2(), like it is done with H264. A
proper fix needs to be found yet.
Fix trac ticket #1386.

mpegvideo: allocate hwaccel privdata after the frame buffer
This ensures the hwaccel privdata does not leak when a frame buffer could
not be allocated (and toggle the assert when the frame is re-used).
Having no frame buffer available is quite common when using the DXVA2
hwaccel in situations where the DXVA2 renderer is being re-allocated, for
example when moving between displays.

This race will always happen sooner or later in a multi-threaded
environment and it will over time lead to OOM.
This fix works by spinning, there are other ways by which this
can be fixed, like simply detecting the issue after it happened
and freeing the over-allocated memory or simply using a mutex.

mpeg12: do not fail on zero dimensions in the sequence header.
The total frame size is a combination of the 12 bits in the sequence
header and 2 more bits in the the sequence extension. While the
specification explicitly forbids the dimensions from the sequence header
from being 0 (thus ruling out multiples of 4096), such videos
apparrently exist in the wild so we should attempt to decode them.

The corresponding codec options (skip_loop, skip_idct, skip_frame) can be
set in a more flexible way.
This technically causes a user interface break, but since the options
were not even documented and we just released a major version that should
not be a serious issue.
