410066986f aic: use chroma scan tables while decoding luma component in progressive mode 
For some unclear reason Apple decided to use the same scan tables for luma and
chroma in the progressive mode while using different ones for luma in the
interlaced mode.

5efbeae38c configure: rename have_incompatible_fork_abi -> have_incompatible_libav_abi 
"Fork" is an ambiguous term, since there may be more than one fork, also
"fork" could be confused with the corresponding function. Also it seems
important to point the name of the referenced fork in the symbol.

Note: the old --enable-incompatible-fork-abi command is retained for
compatibility, although it should be considered deprecated.
