fmtconvert: Add a new method, int32_to_float_fmul_array8
...
This is similar to int32_to_float_fmul_scalar, but
loads a new scalar multiplier every 8 input samples.
This enables the use of much larger input arrays, which
is important for pipelining on some CPUs (such as
ARMv6).

Remove pointless av_cold attributes in header files
...
The init functions marked as av_cold have to be executed in any case,
so there is no gain from trying to mark paths leading to such functions
as unlikely.

cosmetics: rename ff_fmt_convert_init_ppc() to ff_fmt_convert_init_altivec().
...
It only has Altivec functions and is not compiled if Altivec is disabled.

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.
