lib: Add stream_resize_orig and stream_resize_inplace

Start setup for handling of stream_resize into old
and new functions.

Create a stream_resize_inplace function that takes
a double pointer to allow for a realloc operation
to return the possibly moved pointer.

Add a CONFDATE for removal as well.
