tahoe cp: overhaul target assignment, update tests
This substantially changes the internals of "tahoe cp", to behave in accordance with the scheme developed in ticket:2329. test_cli_cp.py got a large new test to exercise all the various combinations. This also changes the set of error messages that "tahoe cp" can produce. This modifies try_copy(), inserts a new implementation of copy_things_to_directory() (and supporting methods), and fixes a few bugs elsewhere. fixes ticket:2329
