boinc

    (app versions don't have a <coprocs> around coproc elements,
    may an oversight but let's stick with it).
    Anyway, I think it's working now.
- lib: remove "owner" array from COPROC.
    This was used in client to keep track of assignment of
    coprocessors to tasks, but we got rid of the reserve/free scheme.
    NOTE: this breaks the mechanism for passing --device N to apps;
    I'll have to do this another way.  Stay tuned.
