Don't need to add "." for file name between the identifier and file extention in the getObject method.
The v1 getExtension method includes '.'. But the v2 version doesn't include it.

Merge the changes from the 2.6 branch into the trunk, fixing filename construction.

Use the ServiceFailure to replace the InvalidRequest when it is the read-only mode (CN throws the exception).

In the replicate method, the checking of the read-only mode was moved from MNodeService class to the MNResourceHandler class since it is asynchronized.

The systemmetadataChanged method is asynchronized, so we put the read-only checking on the ResourceHandler class.

use idFilter for v2 getLogRecords() to match v2 API definition.

check for auth before doing asynch call to MN dirtySysMeta implementation

use request query string first when handling MN.query() method. https://redmine.dataone.org/issues/7384

Put a the systemMetadataChanged method into a queue, so it will not hold the block.

Use the key word "packages" to replace the "package".
