21f9468402 avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPAT 
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.

5bd62a1b3c swscale: fix ticket #4881

80d23d9d32 swscale/swscale: silence unused function warning 
gamma_convert is only used with the old code. Thus, it is
placed under a header guard. This patch silences a -Wunused-function
observed on GCC 5.2.

1e0e193240 sws: add dither enum 
This allows specifying more dither algorithms without using up flags and
without ambiguities.

Also initialize the new field based on the flags and use it.
Note, improving the logic of the checks is left to subsequent
commits, this here only switches from flags to enum.
