[8u] RFR 8151678: com/sun/jndi/ldap/LdapTimeoutTest.java failed due to timeout on DeadServerNoTimeoutTest is incorrect

[Zhengyu Gu]

I would like to backport this patch for parity with Oracle 8u271.

The original patch does not apply cleanly. The conflicts on the fixes
are minors, can be easily resolved manually.

1) LdapTimeoutTest.java is not in ProblemList.txt in 8u
2) Copyright lines in LdapTimeoutTest.java do not match
3) Import lines in BaseLdapServer.java do not match


However, LdapTimeoutTest.java uses some new language features and APIs 
that do not exist in 8u. It also uses new test library that needs to map 
back to 8u test library.
