Metacat

-remove system metadata guid -> local id mapping (there is no document for system metadata now)
-include system metadata elements when replicating data objects (TODO: transfer all system metadata structures with the docinfo request).
TODO: remove docid+rev from the systemMetadata table definition

do not use XML files for storing SystemMetadata - use DB tables only.

Modified Metacat to build against the D1_SCHEMA_0_6_1 branch of the dataone schemas by incorporating the 0.6.1-SNAPSHOT version of d1_common and d1_libclient libraries, and refactoring Metacat code references to the d1 schema changed types.

In order to sync up with DataONE 0.6.1 changes, I'm backing out ObjectFormatService changes temporarily in Metacat. Most functionality will be rolled back in using the DataONE 0.6.2 tag, but some methods in ObjectFormatService (such as getListFromDisk()) will be moved into d1_libclient_java.

Changes in the DataONE ObjectFormat class deprecate the convert() method, and we're now using Metacat's ObjectFormatService to look up object format attributes. The following changes replace ObjectFormat.convert() with ObjectFormatService.getFormat() in several classes....

use update method to update the mapping between local and guid (d1) when we get a force replication request that is an "update

generateMissingSystemMetadata was swallowing Exceptions instead of throwing. Refactored so that specific exceptions are thrown, affecting [create/update]SystemMetadata methods, too.

committing changes related to the new restservice update specification (newPid vs. obsoletedGuid)

replace whitespace in generated docid scope (sanparks patch from 1.9.4 branch)

use outputstream as an object, not a string. relax the Map typing to allow for mixed values. (sanparks patch)
