Justin Ruggles 6410397600 lavr: resampling: add support for s32p, fltp, and dblp internal sample formats 
Based partially on implementation by Michael Niedermayer <michaelni@gmx.at> in
libswresample in FFmpeg. See commits:

Justin Ruggles 8ca08066fc lavr: Use AV_SAMPLE_FMT_NONE to auto-select the internal sample format 
Also make this the default value.

Justin Ruggles acd9948e74 lavr: x86: fix ff_conv_fltp_to_flt_6ch function prototypes 
Changed to match the number of parameters in conv_func_interleave(), which is
how they are called. The change isn't strictly necessary because the 4th
parameter is not used, but the code is clearer if they match.

Justin Ruggles 5cc6d5244d lavr: replace the SSE version of ff_conv_fltp_to_flt_6ch() with SSE4 and AVX 
The current SSE version is slower than the MMX version on Athlon64 and Sandy
Bridge, but the SSE4 and AVX versions are faster on Sandy Bridge.
