forward-port IMPORT_BINARY_PLUGS to OpenJDK7

[Kelly O'Hair]

I'm very confused.

Where did this rt-closed.jar file come from? All the jdk7 copies I have
do not have any jdi class files in them (jdi is all open GPL sources).
The rt-closed.jar files I have all contain only 75 class files
(roughly half jmx/snmp and half media/sound).

The openjdk6 rt-closed.jar file only has 25 jmx/snmp class files in it.

Could this be a very very OLD rt-closed.jar file? Or perhaps someone
copied some rt.jar to rt-closed.jar?

Furthermore, tools.jar does not normally live in the jre (jre/lib/tools.jar)
but above that at lib/tools.jar.

There is something very strange going on here.
