Need reviewers: charsets.jar fix, JarReorder changes, Poller demo change

[Kelly O'Hair]

6933622: Duplicate class files in rt.jar and charsets.jar
6895003: JarReorder is not excluding a requested file.
6939022: Source code adjustments for parfait compilation

http://cr.openjdk.java.net/~ohair/openjdk7/jar-reorder/webrev/

The first two changes are related. Excluding items with JarReorder was  
not working
if the item was also in the ordered classlist. Now excludes apply to  
the ordered classlist.
This JarReorder problem is an old one, one which we also ran into when
javax/crypto/SecretKey.class showed up in rt.jar even when it was  
excluded.
This utility class has been cleaned up and hopefully is considered an  
improved version.

The third fix is a minor change to Poller.c where the C macro ##  
operator was used on
two quoted strings, which caused the Parfait tool some problems and is  
unncessary.

These same changes will also be applied to OpenJDK6.
