Summary: JDK code for package and class renaming from java.dyn to java.lang.invoke.

Includes certain other small changes:
 - move remaining (miscellaneous) contents of sun.dyn to sun.invoke
 - make minor revisions to documentation during Public Review
 - remove the out-of-scope term "SAM type" from documentation and code
 - delete unused methods and classes
 - make minor (API-invisible) code cleanups

The non-renaming changes may be viewed separately here:

This change set is for the JDK repository, specifically:
  http://hg.openjdk.java.net/jdk7/hotspot/jdk

A previous coordinated change set for the JVM, also marked with bug 7012648, is about to be promoted (jdk7-b135).
