0793531859 Bump major version for b8e893399f 
On architectures such as x86 (both 32 bit and 64bit), the stack element
size is fixed, which maintains alignment.  Here, this change does not
break anything. However, we also support also other architectures where
this property is not maintained and therefore, applications will crash
horribly.

This change effectively forces all applications to be recompiled against
libswscale.

97e057ff81 swscale: Fix compilation with --disable-mmx2. 
Some MMX2 functions were being referenced without proper #ifdefs.

4e05830205 swscale: remove misplaced comment. 
The comment should have been placed only in
yuv2rgb48_X_c_template, not yuv2rgb48_1_c_template.

9f63211175 swscale: split out RGB48 output functions from yuv2packed[12X]_c(). 
This is part of the Great Evil Plan to simplify swscale. Note that
you'll see some code duplication between the output functions for
different RGB variants, and even between packed-YUV and RGB
variants. This is intentional because it improves readability.

0af8a71d66 swscale: fix JPEG-range YUV scaling artifacts. 
YUV planes were marked as uint16_t, but they contained signed data.
Fixes issue 1108 and 675.

6d4d483eee swscale: de-macro'ify RGB15/16/32 input functions. 
Inline functions are easier to read, maintain, modify and test,
which justifies the slightly increased source size. This patch
also adds support for non-native endianness RGB15/16 and fixes
isSupportedOutput() to no longer claim that we support writing
non-native RGB565/555/444.

6e5a8d3c9a swscale: fix function declarations in swscale.c. 
Remove inline keyword from functions that are never inlined.
Use av_always_inline for functions that should be force-inlined
for performance reasons. Use av_cold for init functions.

a27db4c349 swscale: fix function declaration keywords in x86/swscale_template.c. 
Remove inline keyword for functions that are only called through
their function pointers (and thus cannot be inlined); add av_cold
keyword to init function, and use av_always_inline instead of
inline for functions that must be inlined for performance reasons.

9bcbb250e2 swscale: fix types of assembly arguments. 
This prevents the following compiler warnings: "warning:
initialization from incompatible pointer type". Since the
variables are only ever used in inline assembly, their type
is actually irrelevant (so the part where it was wrong did
not invoke any buggy behaviour).

ea28175312 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.
