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.

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.

Fix handling of input if not in native endianness, and add support for
9/10-bit output. This allows us to force endianness of YUV420P 9/10bit
in the H264/10bit fate tests, which should fix them on big-endian
systems.

This is on a Nehalem i7. Despite being a 500 frame, 720p video, the numbers
fluctuate, so I took an average of 4 runs.
Another reason I'd like this change is youtube accepts videos with higher
resolutions than 5120.
16384 is vp8's maximum resolution, so that should keep us amused for a
little longer.

Remove dependency from swscale-example.c to swscale_internal.h by duplicating
