closing bugs in goose and gwacl

[Curtis Hovey-Canonical]

There are many Fix Committed bugs in goose and gwacl. Since we don't
go regular releases of these libraries, their bugs remain open for a
long time.

Do we want to do regular releases? Do we consider their use in a
release stable juju-core to be Fix Released? Do we care about releases
at all since Go prefers branch tips, not releases?
