use P2P protocol for drop
Not yet used for everything else, but this is enough to
verify that it works, and do some benchmarking.
Some bugfixes included, which got it working. Also fallback to old
actions has been verified to work correctly.
Benchmarked dropping one thousand files from a ssh remote on localhost.
Using the old git-annex 40.867 seconds.
With the P2P protocol 9.905 seconds!
