Add ctx parameter and remove embedded contexts for API regularity.

Purge several embedded contexts:

Remove embedded context in fz_output.
Remove embedded context in fz_stream.
Remove embedded context in fz_device.
Remove fz_rebind_stream (since it is no longer necessary).
Remove embedded context in svg_device.
Remove embedded context in XML parser.

Add ctx argument to fz_document functions.

Remove embedded context in fz_document.
Remove embedded context in pdf_document.
Remove embedded context in pdf_obj.

Make fz_page independent of fz_document in the interface.

We shouldn't need to pass the document to all functions handling a page.
If a page is tied to the source document, it's redundant; otherwise it's
just pointless.

Fix reference counting oddity in fz_new_image_from_pixmap.
