e123295cc8 avcodec/proresdec2: Rename to proresdec
Once upon a time, there used to be a LGPL and a GPL ProRes decoder
in FFmpeg; the current decoder evolved from the second of these.
But given that it is now the only ProRes decoder we have, it's file
should simply be named proresdec.c (which also brings it in line with
its header).

0bbb1cdc28 Use correct LOCAL_ALIGNED for stack variables instead of DECLARE_ALIGNED.
LOCAL_ALIGNED should work for all compilers/systems whereas
DECLARE_ALIGNED does not work on some (do not remember which though).
