the parallelism and parallelism-chunk-size flags
which used to control how many parts to split a
segment into and many to perform in parallel
are now deprecated and replaced by
maximum-concurrent-pieces and long-tail-margin.
now, for an individual transfer, the total number
of piece uploads that transfer will perform is
controlled by maximum-concurrent-pieces, and
segments within that transfer will automatically
be performed in parallel. so if you used to set
your parallelism to n, a good value for the pieces
might be something approximately like 130*n, and
the parallelism-chunk-size is unnecessary.

recursive copy had a bug with relative local paths.
this fixes that bug and changes the test framework
to use more of the code that actually runs in uplink
and only mocks out the direct interaction with the
operating system.
