2016-01-27avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPATDerek Buitenhuis
Libav, for some reason, merged this as a public API function. This will aid in future merges. A define is left for backwards compat, just in case some person used it, since it is in a public header. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

2015-10-10doc/scaler, swscale/options: use proper capitalizationGanesh Ajjanagadde
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.

2015-10-04all: add _DEFAULT_SOURCE locally wherever neededGanesh Ajjanagadde
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.
