[7u6] Request for approval for CR 7136506 FDS: rework jdk repo Full Debug Symbols support

[Daniel D. Daugherty]

Greetings,

This is a request to backport a JDK 8 fix into JDK 7u6:

7136506 3/4 FDS: rework jdk repo Full Debug Symbols support
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7136506

The fix has already been pushed to JDK 8, as:

http://hg.openjdk.java.net/jdk8/tl/rev/fa0fed83e335
http://hg.openjdk.java.net/jdk8/tl/jdk/rev/e7f813f2ea86

This fix along with its companion HotSpot changes have been
reviewed on hotspot-dev at openjdk.java.net,
serviceability-dev at openjdk.java.net and build-dev at openjdk.java.net.
The companion install repo changes have been reviewed internally
and were pushed for JDK8-B33 and JDK7u6-B04.

The JDK7u6 and JDK8 jdk repo patch files:
   - identical except for timestamps, some line numbers,
     and some context diff anchors
   - no content difference between JDK7u6 and JDK8

I will coordinate the timing of this push with Lana because these
changes should be pushed to JDK7u6-B04 or later, i.e., the install
repo changes should get into the same JDK7u6 build or earlier.

Dan
