[RFC][IcedTea-Web]: Removing dead unused commented code

[Andrew Su]

Hello,

This patch is an attempt to remove dead, unused or commented code from the plugin directory in icedtea-web. 

(I have provided the patch for each file separately for easier reading.) 

Some comments though..
 General Note:
    Changed the copyright to be 2011 for all the modified files.

 These are the methods that will be removed with the patch (unused private methods)
    PluginMessageConsumer.java:getReference(String[])
    PluginMessageConsumer.java:isInInit(Integer)
    PluginMessageConsumer.java:dumpWorkerStatus()
    PluginAppletViewer.java:makeReader(InputStream)
    PluginMessageConsumer.java:getReference(String[])
    PluginMessageConsumer.java:isInInit(Integer)
    PluginMessageConsumer.java:dumpWorkerStatus()
 
 In the following method, will we be needing this block of commented out conditions in the future?
    PluginAppletSecurityContext.java:getAccessControlContext(String[], String)


I have tried building it and that succeeds. Tested running some simple applets and those seem to work as well.

Questions comments concerns?

Regards,
  Andrew
