[14] RFR JDK-8228613 "java.security.Provider#getServices order is no longer deterministic"

[Valerie Peng]

Anyone can help review this fix? SUN provider supports multiple impls of 
SecureRandom and rely on the ordering of the set returned by 
Provider.getServices() to choose the most preferred RNG algo for new 
SecureRandom() calls. Instead of maintaining the ordering, I think it's 
faster and more robust to use an alias "DEFAULT" to indicate the most 
preferred RNG algo for SUN provider.
