f3fc103c6a doc/resampler, swresample/options: use proper capitalization 
Proper names should be capitalized in all user facing API as far as
possible. The option names themselves have not been changed since:
1. We consistently keep option names in lower case.
2. Changing them would break existing scripts.
3. I suspect that we want to be similar to Sox and its relevant options.

The converse is also true: improper names should not be capitalized
generally.

24e6729a04 swresample/dither: use integer arithmetic 
This fixes a -Wabsolute-value reported by clang 3.5+ complaining about misuse of fabs() for integer absolute value.
An additional benefit is the removal of floating point calculations.

5750d6c5e9 x86: move XOP emulation code back to x86inc 
Only two functions that use xop multiply-accumulate instructions where the
first operand is the same as the fourth actually took advantage of the macros.

This further reduces differences with x264's x86inc.

4977692461 swresample: Choose 16bit internally only if input and output is 16bit or less 
or if no rematrix and no resampling is performed and the input is 16bit
note reampling and rematrix itself always use more than 16bit internally
the "internal" sampling format is the format between these steps

Its unlikely the difference from this commit is audible in any case
unless there is some bug either before or after the change.
but multiple people prefer this and it slightly improves the precission
of computations.
