Title: Copy closure progress: Size tracking and a bug fix

With these commits, --show-progress will have a progress bar with an end point and an ETA. To do this accurately, the pv was moved outside of the calls to compressor and decompressor, and to compensate for the resultant jumps in transfer rate these commits use the -a flag to pv to show the average transfer rate. Also, build-remote was updated to CopyClosure::copyTo's new argument list.
