Using lfg was an overkill in this case where the random numbers
were only used for encoder descisions. Should increase result
uniformity between different FPUs and gives a slight speedup.

The spec says:
"Mandatory elements with a default value may be left out of the file. In the absence
of a mandatory element, the element's default value is used."

Fixes ticket #5872.

Fixes ticket #4009.

Fixes decoding of the output file from ticket #4009.

The option d10_channelcount only exists for mxf_d10.

Attachment tags were being written targeting non-existent streams in the
output file.
Also filter filename and mimetype entries, as they are standard elements
in the Attachment master.

The parser for the outdef will accept a negative value for the first
named channel's gain. As negative values effectively only invert the
phase of the signal, and not negate the level, the gains' absolute
values must be used to correctly accumulate the levels.

The optimizations of mipsdsp are not supported by all loongson cpu.
The optimizations of mipsfpu and mipsdspr2 maybe supported by 3A2000/3A3000/3A4000 but not tested yet.
Loongson only support mmi (loongSIMD) optimizations now.

The slice index expected by D3D11VA is the one from the texture not from the
array or texture/slices.

In VLC the slices we provide the decoder don't start from 0 and thus pictures
appear in bogus order. With possible crashes and corruptions when using an
invalid index.
