use new stream code instead of raw file * stuff.

1999-05-31  bertrand  <Bertrand.Guiheneuf@inria.fr>

	* tests/test2.c (main):
	use new stream code instead of raw file * stuff.

	* camel/gmime-utils.c (get_header_table_from_stream):
	new func. Will replace get_header_table_from_file and will
	be used to parse headers from files as well as from
	memory buffers.

	* camel/camel-stream-fs.c:
	CamelStream Subclass. File system based
	stream.
