remove get/set_output_stream operations. They're redundant with

	* camel-data-wrapper.c: remove get/set_output_stream operations.
	They're redundant with write_to_stream, and CamelMimePart and
	CamelMimeMessage only implement the latter, meaning that trying to
	get_output_stream on a CamelMimeMessage that was built from pieces
	rather than being parsed from a stream doesn't work. Anything that
	uses get_output_stream can be rewritten to use write_to_stream, so
	we'll standardize on that.
	(camel_data_wrapper_new): remove this: CamelDataWrapper is
	supposed to be an abstract class.
	(write_to_stream): remove default implementation. (Moved to
	CamelSimpleDataWrapper)

	* camel-simple-data-wrapper.c: resurrect, although it's not really
	the same thing it was before. A simple data wrapper, which is
	backed by a CamelStream.

	* camel-mime-part-utils.c
	(simple_data_wrapper_construct_from_parser): Use
	construct_from_stream rather than set_output_stream.
	(camel_mime_part_construct_content_from_parser): Change
	camel_data_wrapper_new to camel_simple_data_wrapper_new.

	* camel-mime-part.c (camel_mime_part_set_content): Change
	camel_data_wrapper_new to camel_simple_data_wrapper_new.
