3b905b9fe6 swscale: Deprecate vector functions which are unused outside swscale 
There are no known users of these functions within debian
It should be thus possible to remove these functions without recommandition of a
replacement

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.
