Make cairo_output_stream_t an embeddable type.

Most internal cairo types are transparent within cairo and have init and fini
functions to intialize and finialize them in place.  This way they can be
easily be embedded in other structs or derived from.  Initially, the
cairo_output_stream_t type was proposed as a publically visible type and
thus kept opaque.  However, now it's only used internally and derived from
in a number of places so let's make it an embeddable type for consistency
and ease of use.

The patch keeps _cairo_output_stream_create() and _cairo_output_stream_close()
around for (internal) backwards compatibility by deriving a
cairo_output_stream_with_closure_t stream type.

The patch also moves all cairo_output_stream_t functions out of cairoint.h
and into new file cairo-output-stream-private.h, thus chipping away at the
monolithic cairoint.h.
