Metacat

check for null docid from access table -- using guid for many system meta rows

use docImpl getBytes() to preserve encoding
no need to catch an exception only to throw it (those I was playing around with looking up the fmt from the d1_common lib if it was not found on the server...but this is redundant with other client code)

remove resolve() test -- not implemented in Metacat

handle data objects (not sci meta) and also set the resulting pid so that create() can succeed

catch exceptions from system meta data query and throw service failure rather than swallowing them with an error msg

handle null values from DB better when querying system metadata

Update getOperationStatistics() to reflect the change in the signature, using ObjectFormatIdentifier instead of ObjectFormat.

Modify monitor() to accept new parameters for getOperationStatisics() (fromDate, toDate) instead of 'period'. Added getDateAsUTC() to parse incoming fromDate and toDate parameter strings.

Fixed problems in IdentifierManager asSystemMetadata(), getSystemMetadata(), and querySystemMetadata() that were using ObjectFormat.toString() rather than ObjectFormat.getFmtid().getValue(). Metacat was storing the string memory pointer rather than the actual format string in the systemmetadata table.

use super class' create() method
use string comparison for assertRelation method
