c0fd2fb27b swscale: Rename sws_context_class to ff_sws_context_class 
It is an internal swscale symbol and thus should not be exported.

70d418c7e6 Revert "PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 VSX SIMD." 
This reverts commit 1df908f33f. The expected
performance improvements are essentially non-existent.

1df908f33f PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 VSX SIMD. 
This patch addresses Trac ticket #5570. The optimized functions are in file
libswscale/ppc/input_vsx.c. Each optimized function name is a concatenation of the
corresponding name in libswscale/input.c with suffix _vsx.

cab9661dba sws/aarch64/yuv2rgb: honor iOS calling convention 
y_offset and y_coeff being successive 32-bit integers, they are packed
into 8 bytes instead of 2x8 bytes.

See https://developer.apple.com/library/ios/documentation/Xcode/Conceptual/iPhoneOSABIReference/Articles/ARM64FunctionCallingConventions.html

> iOS diverges from Procedure Call Standard for the ARM 64-bit
> Architecture in several ways
[...]
> In the generic procedure call standard, all function arguments passed
> on the stack consume slots in multiples of 8 bytes. In iOS, this
> requirement is dropped, and values consume only the space required.
[...]
> Padding is still inserted on the stack to satisfy arguments’ alignment
> requirements.

3b2000c2bf doc/scaler, swscale/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.

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

Glibc 2.20 onwards generates a deprecation warning for usage of _BSD_SOURCE and _SVID_SOURCE.
The solution from man feature_test_macros is to define both _DEFAULT_SOURCE and the old macros.
This solution is on the lines of the one in commit af1818276e.
