Leo Izen ad77345a5d avcodec/exif: add EXIF parser and struct API ...

This commit adds a structure to contain parsed EXIF metadata, as well
as code to read and write that struct from/to binary EXIF buffers. Some
internal functions have been moved to exif_internal.h. Code to read
from this new struct and write to an AVDictionary **dict has been added
as well in order to preserve interoperability with existing callers.
The only codec changes so far as of this commit are to call these
interop functions, but in future commits there will be codec changes to
use the new parsing routines instead.
