98db4e2a4e PPC: Move types_altivec.h and util_altivec.h from libavcodec to libavutil
This will allow for easier implementation of Altivec functions in libraries
other than libavcodec.

c73d99e672 Separate format conversion DSP functions from DSPContext.
This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

952e872198 Drop unused args from vector_fmul_add_add, simpify code, and rename
The src3 and step arguments to vector_fmul_add_add() are always zero
and one, respectively.  This removes these arguments from the function,
simplifies the code accordingly, and renames the function to better
match the new operation.
