Ganesh Ajjanagadde 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.

Ganesh Ajjanagadde 26e8895b73 all: add _DEFAULT_SOURCE locally wherever needed 
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.
