swscale: remove alp/chr/lumSrcOffset.
...
They are hacks added to reuse the same scaling function for
different formats and they may cause problems when SIMD
implementation of the same functions are used along with pure
C functions.

Remove duplicate "inC" and "_c" functions that do the same thing;
give each function that handles data and acts as a function pointer
a "_c" suffix; remove "_c" suffix from functions that are inherently
not optimizable. Remove inline keyword from functions that are only
used through function pointers.

swscale: reintroduce sws_format_name() symbol
...
Reintroduce the internal symbol which was removed in:
commit e1197b9e17
Author: Stefano Sabatini <stefano.sabatini-lala@poste.it>
Date: Sun May 29 17:57:40 2011 +0200
swscale: remove sws_format_name()
Use av_get_pix_fmt_name() instead.
The symbol is used by some external libs (hi libx264!), this gives
time to them to use the recently added av_get_pix_fmt_name() rather
than an internal symbol.
