3.0.0

Add a --verify flag to baton-put and "verify" to baton-do "put" operations. This validates the uploaded file against a checksum provided by the client. The client should provide a default checksum algorithm, otherwise it will fall back to iRODS' default. The checksum and verify options are mutually exclusive.

No longer force checksum re-caculation in baton_json_checksum_op.

Change signature of put_data_obj to add iRODS default resource.

Change option_flags enum order.

Change return type of checksum_data_obj.

Remove iRODS 4.1.12 from the test matrix.

Bugfix: double free for query input when listing checksums of a dataobject that has inconsistent checksums.
