RFR:7184195 - java.util.logging.Logger.getGlobal().info() doesn't log without configuration

[Jim Gish]

Please review

<http://cr.openjdk.java.net/%7Ejgish/Bug7184195-global-logger-failure.1/>

This is a simple fix that removes a long-standing bug in acquiring a 
using the global Logger in which Logger.getGlobal().info() (for 
example), would not log without additional configuration that would 
trigger LogManager initialization.  I have also added a test to reassure 
us that I have not introduced a deadlock between LogManager 
initialization and getting the global logger.

In addition, I've introduced a utility class I developed during a recent 
fix to a logging deadlock, which helps us detect and report on the 
details of a deadlock.

Thanks,
    Jim
