offload: '{send,receive}-files' wait for completion of the transfer.
Fixes situations where the remote 'guix build' is invoked before the
.drv has been completely copied, as reported at
<https://lists.gnu.org/archive/html/guix-devel/2014-04/msg00174.html>.
In some cases 'send-files' would return before the other end is done
importing the files, and so the subsequent 'guix build' invocation would
just miss the .drv file it refers to.

Partially fixes <http://bugs.gnu.org/17212>.

'tree-union' and 'delete-duplicate-leaves' exports. Merge inputs in a
breadth-first fashion. Follow symlinks for purposes of making decisions
about the merge.
