Optimize listpack for stream usage to avoid repeated reallocs (#6281)
Avoid repeated reallocs growing the listpack while entries are being added.
This is done by pre-allocating the listpack to near maximum size, and using
malloc_size to check if it needs realloc or not.
When the listpack reaches the maximum number of entries, we shrink it to fit it's used size.
