	* gbufferedinputstream.c: (g_buffered_input_stream_peek_buffer),
	(g_buffered_input_stream_read_byte):
	* gbufferedinputstream.h:
	New functions for efficient access to buffer and simple single byte
	reads.

	* gdatainputstream.c: (scan_for_newline), (scan_for_chars),
	(g_data_input_stream_read_until):
	* gdatainputstream.h:
	Use peek_buffer to avoid memcpy in scan_for_newline, implement
	read_until with multiple stop chars.
