Nedeljko Babic	e374405d8e	libavutil: Cosmetic changes to fixed_dsp file. Names of functions vector_fmul_window_fixed_c and vector_fmul_window_fixed_scaled_c are changed by removing "_fixed" from the name since it is redundant.

Nedeljko Babic	3827a86eac	Optimization of AMR NB and WB decoders for MIPS AMR NB and WB decoders are optimized for MIPS architecture. Appropriate Makefiles are changed accordingly. Cnfigure script is changed in order to support optimizations. Optimizations are enabled by default when compiling is done for mips architecture. Appropriate cflags are automatically set. Support for several mips CPUs is added in configure script. New ffmpeg options are added for disabling optimizations. The FFMPEG option --disable-mipsfpu disables MIPS floating point optimizations. The FFMPEG option --disable-mips32r2 disables MIPS32R2 optimizations. The FFMPEG option --disable-mipsdspr1 disables MIPS DSP ASE R1 optimizations. The FFMPEG option --disable-mipsdspr2 disables MIPS DSP ASE R2 optimizations.
