parse method takes CharSequence, not String

[glassfishrobot]

Submitted by David Bau, entered initially by Joe Fialli

For javax.xml.datatype.Duration and javax.xml.datatype.XMLGregorianCalendar,
the parser methods have a parameter of type String. To enable efficient
implementations that take advantage of java.nio, it would be preferable
if these parse methods took a CharSequence instead. In JDK 1.4, String
implements CharSequence.

Note that javax.xml.bind.DatatypeConverterInterface and DatatypeConverter
would also need to be changed to make the most of efficiencies being requested
by this change.
