Use CamelException to signal failure. (camel_stream_write_strings):

	* camel-stream.c (camel_stream_read, camel_stream_write,
	camel_stream_flush, camel_stream_reset, camel_stream_printf,
	camel_stream_write_to_stream): Use CamelException to signal
	failure.
	(camel_stream_write_strings): Remove. camel_stream_printf is more
	useful in most of the places that used this.
	(camel_stream_write_string): Change from macro to function to
	prevent problems with double-evaluation.

	* camel-seekable-stream.c (camel_seekable_stream_seek,
	camel_seekable_stream_set_bounds): Use CamelException.
	(reset): Update.

	* camel-seekable-substream.c, camel-stream-buffer.c,
	camel-stream-filter.c, camel-stream-fs.c, camel-stream-mem.c:
	Update.

	* camel-stream-fs.c: Remove the virtual init functions and move
	the code into the creator functions. Add CamelExceptions to
	creation functions that could fail.

	* camel-data-wrapper.c (camel_data_wrapper_write_to_stream): Use
	CamelException.
	* camel-mime-message.c, camel-mime-part.c, camel-multipart.c
	(write_to_stream): Update.

	* camel-mime-parser.c: add an exception to the mime parser private
	data and pass that to stream functions as needed.

	* gmime-content-field.c, md5-utils.c: Update (badly) for stream
	changes.

	* camel-exception.h (camel_exception_is_set): convenience macro.

	* providers/Makefile.am: disable SMTP for now

	* providers/mbox/camel-mbox-folder.c (mbox_append_message): Pass
	CamelException to the functions that now need it. Check the
	exception after calling camel_stream_flush, and fail if it fails.
	(mbox_get_message_by_uid): More updates.

	* providers/pop/camel-pop3-folder.c,
	providers/pop/camel-pop3-store.c,
	providers/sendmail/camel-sendmail/transport.c: Update.
