    StaxConverter: Make input and output factory pool size implementation… 
(#6380)
    
    * StaxConverter: Make input and output factory pool size implementation 
match comments.
    
    Comments suggests that Runtime#availableProcessors should be used as pool 
size when it is greater than 20, but the current implementation uses 
Runtime#availableProcessors regardless of the amount of processors available if 
the system property "org.apache.cxf.staxutils.pool-size" is not set.
    
    * StaxConverter: Stop using the system property 
"org.apache.cxf.staxutils.pool-size" when determining the input and output 
factory pool size.
