RFR (JAXP): 8024378 : StAX parser shall support JAXP properties

[huizhe wang]

It appears the previous patch was one line short of supporting setting 
the JAXP's new property ElementAttributeLimit through the StAX factory, 
that is, resetting the variable in reset(PropertyManager 
propertyManager) as well.  Other than that, I also moved the common 
reset items from reset(XMLComponentManager...) and reset(PropertyManager 
...) to a new method called "resetCommon".

The real change is to set the following in both reset methods, now in 
resetCommon:

663 fElementAttributeLimit = 
fSecurityManager.getLimit(XMLSecurityManager.Limit.ELEMENT_ATTRIBUTE_LIMIT);


Thanks,
Joe
