[mime-data] Allow embedding of arbitrary mime-types. Use the surface user-data array allow to store an arbitrary set of alternate image representations keyed by an interned string (which ensures that it has a unique key in the user-visible namespace). Update the API to mirror that of cairo_surface_set_user_data() [i.e. return a status indicator] and switch internal users of the mime-data to the public functions.

[surface] Pass a separate closure for the mime-type destroy notifier. A limitation of the current API was that the destroy notifier was called on the mime-data block. This prevents the user from passing in a pointer to a managed block, for example a mime-data block belonging to a ref-counted object. We can overcome this by allowing the user to specify the closure to be used with the destroy notifier.

Add CCITT_FAX mime type for PDF and PS surfaces This completes the full set of PDF/PS image filters allowing image data to be passed though without decompressing then recompresssing in a less efficient format. The difficulty with CCITT_FAX is it needs some decoding parameters that are not stored inside the image data. This is achieved by using an additional mime type CCITT_FAX_PARAMS that contains the params in key=value format.
