RFR(13): JDK-8217047: Provide a way to inject missing parameter names

[Jan Lahoda]

Hi,

Based on feedback, I've updated the javadoc. Also, when 
ParameterNameProvider.getParameterName returns null, the javac's default 
name will be returned from VariableElement.getSimpleName(), so I've made 
this explicit in the javadoc and added a test for that.

Updated webrev: http://cr.openjdk.java.net/~jlahoda/8217047/webrev.02/
Updated specdiff:
http://cr.openjdk.java.net/~jlahoda/8217047/specdiff.02/overview-summary.html

How does this look?

Thanks,
     Jan
