Rhino build support

[Henri Gomez]

The only source of information found was IcedTea 1.7 (1.14) with
patches/rhino.patch

1) CLOSED_SRC test removed (jdk/make/com/sun/Makefile)

-ifndef OPENJDK
-  ORG_EXISTS := $(call DirExists,$(CLOSED_SRC)/share/classes/sun/org,,)
-  ifneq ("$(ORG_EXISTS)", "")
-    SCRIPT_SUBDIR = script
-  endif
-endif

2) rhino.jar added to build (jdk/make/com/sun/script/Makefile)

3) sun.org.mozilla.javascript.internal.* moved to
sun.org.mozilla.javascript.*
(jdk/src/share/classes/com/sun/script/javascript/*)

4) repackaged rhino.jar copied under JRE /lib/rhino.jar
(jdk/make/common/Release.gmk)

5) rhino.jar added to runtime jars (hotspot/src/share/vm/runtime/os.cpp)

All of these could be done on bsd-port and macosx-port.

Did there is interest to do this in bsd-port, or macosx-port ?

If not, It will be available only on openjdk-osx-build packages (if
not licence problem occurs)

Cheers
