[stream] Add quad-word support and stream_resize
2006-01-10 Paul Jakma <paul.jakma@sun.com>
* stream.c: (stream_new) Allocate stream data as seperate object.
(stream_free) free the data.
(stream_resize) new function, resize stream to new size.
(stream_{get,put}q*) new functions to get/put quad word size
types.
* stream.h: (struct stream) make data seperate from the stream.
Export new stream_resize and quad-word get/put functions.
