RFR: 8174735 Update JAX-WS RI integration to latest version

[Roman Grigoriadi]

Hi,

Please review standalone JAXB/JAXWS changes, synced to jdk/jaxws repo.

JBS: https://bugs.openjdk.java.net/browse/JDK-8174735
Webrev: http://cr.openjdk.java.net/~aefimov/jaxws-integrations/8174735/00/

You can find change list in the description of JBS and its linked 
issues. Most diffs are for SAAJ-RI related to JDK-8166745 - remove 
dependencies on jdks Xerces internal classes.

Thanks,
Roman
