mov: Add support parsing QuickTime Metadata Keys.
The Apple dev specification:
https://developer.apple.com/library/mac/documentation/QuickTime/QTFF/Metadata/Metadata.html
Basically the structure is like:
|--meta
|----hdlr
|----keys
|----ilst
1) The handler type in the metadata handler atom is ‘mdta’.
2) The key and value are stored separately for each key-value pair.
The 'keys' atom stores the key table, while 'ilst' atom stores the
values corresponding to the indices in the key table.
