[1.10, 1.11, 2.1 & 2.2 APPROVAL] jar uf support broken with 7143606 security fix

[Andrew Hughes]

See http://mail.openjdk.java.net/pipermail/core-libs-dev/2012-June/010712.html
which applied the fix to 8 and 7u6 (thus the fix is in 2.3).

The jar bug rears its head in OpenJDK builds as HotSpot updates sa-jdi.jar with
a service META-INF file, changing its permissions to 600.  It's pretty simple
to replicate with any old jar file:

$ jar cf crap.jar crap
$ ll crap.jar 
-rw-r--r-- 1 andrew staff 924 Oct 15 14:03 crap.jar
$ /mnt/builder/jdk6/j2sdk-image/bin/jar uf crap.jar -C /mnt/builder/icedtea6-1.11/openjdk/hotspot/agent/src/share/classes META-INF/services/com.sun.jdi.connect.Connector
$ ll crap.jar 
-rw------- 1 andrew staff 1.2K Oct 15 14:04 crap.jar

Whoops!

For 1.10 & 1.11, we can "fix" this by simply dropping the native2ascii & jar parts
of that security fix.  For 6-HEAD, 2.1 & 2.2, those parts of the patch actually need
to be reverted.  I'll also push the 6 fix upstream to OpenJDK6.

Ok for 1.10, 1.11, 2.1 & 2.2?
