From review: changes in BKE_image_has_anim() and BKE_image_has_packedfile()

Comments by Sergey Sharybin:

* If packedFile becomes NULL for some and ima->packedfiles has still
elements this sounds like a horrible error happened somewhere.

* If anims has items then the image is an animation. Imagine situation
when you load movie file in image editor, save .blend file, then
remove the movie file and re-load the file. Seems this case should be
considered image is an animation i guess.

From review: revert uneeded change in branch

From review: image is calloc'ed, no need to initialize ListBases to NULL

From review: use BLI_duplicatelist and fix for copy_image_anims

It makes no sense to have a ImageAnima when the struct anim itself is
NULL;

From review: use BLI_freelistN
