Metacat

Merge 1.9.2 changes back into the trunk

Modified ResourceHandler to return error codes in XML format for the get() method.

Modifications to metacat rest service to use the new DataONE CrudService for
get() operation. Minor issue with permissions errors propagating up the
stack, but otherwise this is the first implementation of a full DataONE
method.

Modified readFromMetacat() to pass most exceptions up the call stack, which
allows creation of new entry points for calling reads. Still need to
continue factoring out the HTTPServletResponse that is passed in in order to
make entrypoints that are not servlet based possible. Problem now is in...

Refactored putObject method to separate the create() and update() portions in order to match the method signatures needed for DataONE.

Modified ResourceHandler.deleteObject() to take a globally unique id (guid)
as input rather than a metacat-conformant docid. The guid is translated
into a metacat docid which is then used in the handleDelete() call. So now
Metacat supports use of arbitrary identifiers for delete operations, but...

Added support to ResourceHandler to allow the putObject method to use
arbitrary guid strings as input. These strings are examined, and if they
match the Metacat docid format (scope.id.rev), they are used directly. If
the id is a string in another format, a new localId is generated based on...

Fixed bug in getNextRevision() where "error" documents were not being
detected properly before searching for the next identifier.
