a slight bias towards dark green in the interpolated area. Rounding

avcodec/jpeg2000: replace naive pow call with smarter exp2fi

pow is a very wasteful function for this purpose. A low hanging fruit
would be simply to replace with exp2f, and that does yield some speedup.
However, there are 2 drawbacks of this:
1. It does not exploit the integer nature of the argument.
2. (minor) Some platforms lack a proper exp2f routine, making benefits available
only to non broken libm.
3. exp2f does not solve the same issue that plagues pow, namely terrible
worst case performance. This is a fundamental issue known as the
"table-maker's dilemma" recognized by Prof. Kahan himself and
subsequently elaborated and researched by many others. All this is clear from benchmarks below.

This exploits the IEEE-754 format to get very good performance even in
the worst case for integer powers of 2. This solves all the issues noted
above. Function tested with clang usan over [-1000, 1000] (beyond range of
relevance for this, which is [-255, 255]), patch itself with FATE.

Benchmarks obtained on x86-64, Haswell, GNU-Linux via 10^5 iterations of
the pow call, START/STOP, and command ffplay ~/samples/jpeg2000/chiens_dcinema2K.mxf.

avcodec/h264: Set CORRUPT flag on output frames that are not fully recovered

In the merge commit 78265fcfeee153e5e26ad4dbc7831a84ade447d6 this behaviour
was broken and the CORRUPT flag would never ever be set on a frame. However
the flag on the AVCodecContext was taken into account properly, including
AV_CODEC_FLAG2_SHOW_ALL.

The reason for this was that the recovered field of the next output picture
was always set to TRUE whenever one of the two AVCodecContext flags was set,
which made it impossible to detect later, before outputting, if the frame was
really recovered or not. Now don't set it to TRUE unless the frame is really
recovered and check the AVCodecContext flags right before outputting.

avcodec/libdcadec: implement logging callback

Don't print a warning when dcadec_context_filter() returns positive
warning code. Most relevant warnings are now output through the callback
function.

avcodec/libdcadec: fix request_channel_layout

Take request_channel_layout as a hint and don't force 2.0 downmix by
using both the 2CH and 6CH flags together.

Remove warnings about missing coefficients because they are no longer
relevant.

Honor AV_CH_LAYOUT_NATIVE and make it possible for native DTS channel
layout to be output.
