Noah Treuhaft 63468ef4a8 Use multipart upload API in S3 Move method
This change to the S3 Move method uses S3's multipart upload API to copy
objects whose size exceeds a threshold.  Parts are copied concurrently.
The level of concurrency, part size, and threshold are all configurable
with reasonable defaults.

Using the multipart upload API has two benefits.

* The S3 Move method can now handle objects over 5 GB, fixing #886.

* Moving most objects, and espectially large ones, is faster.  For
  example, moving a 1 GB object averaged 30 seconds but now averages 10.
