Metacat

Add two method: handleGetDataFileRequest and handleForceReplicateDataFile. The two methods will handle data file replication.

Adding handle force replication data file part.

Add a new method named unRegisterDocument. This method will delete the record in xml_document table which is for a data file

Figure out the configuration issue about replication. If metacat was configured to set replication off in build.xml, it will reject replication.

Adding a method named handleGetDataFileRequest. User can download data file from replcication now.

Currently, some document in xml_document table doesn't have entries in
xml_access table. This is okay during the old access policy.
But we changed the access policy( see bug 437 ) and if there is no entry in
xml_access table, except owner, other person can not access it....

Fixed the bug that handle force replication

Fixed the bug that to handle forceReplication action

Add a method named getLocalReplicationServerName

Fixed the bug metacat will set server location to 1, no matter it is.

Fixed the getall didn't work. Now local host can insert or update documents from remote host.
But still there some problem on force replcation.
