If a blob is larger than the configured big-file-threshold, instead of reading it into a single buffer obtained from malloc, stream it onto the end of the current pack file. Streaming the larger objects into the pack avoids the 4+ GiB memory footprint that occurs when fast-import is processing 2+ GiB blobs. Signed-off-by: Shawn O.
