[8u] RFR 8160768: Add capability to custom resolve host/domain names within the default JNDI LDAP provider

[Langer, Christoph]

Hi Zhengyu,

I have now created CSR JDK-8251380 for 11u and JDK-8251270 is 8u again, back on your name.

I think, we should not do changes to src/share/classes/javax/naming/directory/InitialDirContext.java. The changes are Javadoc only but they'd alter the spec, so we rather should not touch that file. I've also stated in the CSRs that the file isn't touched by the backports.

As for failing tests - I also see some in 11u. The initial version was a bit shaky, I guess. There are follow up fixes which have been backported by Oracle as well (JDK-8139965, JDK-	8237834). I'll pick these for 11u, too.

Best regards
Christoph
