Mans Rullgard	50be207759	amrwbdec: fix invalid pointer arithmetic Subtracting a (positive) value from the address of an array violates C99 section 6.5.6: If both the pointer operand and the result point to elements of the same array object, or one past the last element of the array object, the evaluation shall not produce an overflow; otherwise, the behavior is undefined.

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.
