#8573: Image attachment Exif should be stored in individual post meta entries

 Currently, image Exif information is stored in one big serialized post
 meta entry. This makes it impossible to query against an individual entry
 (for instance, querying all images shot at 50mm).

 It's easy enough to separate them out with an upgrade routine, and have
 new images put each Exif value in its own post meta entry. The question is
 backwards compatibility.  Should we drop the old serialized info? Should
 we leave it and just not ever update it? We could make a compatibility
 layer (would involve a filter on postmeta updates that looks for changes
 to the individual keys or the serialized key, and sync changes made in one
 to the other).

 My vote is to leave the old data, but not populate it for new attachments.
 Thoughts?
