Changes to ClassAnalyzer tool

[Mandy Chung]

Alan,

Per our discussion, I made the following changes in the tool:

1. Supports multiple modules in one single config file.   I merged all 
41 *.config files into one new modules.rootset file.  The tool can still 
take multiple -config options.

2. Rename "contents" to "include" key name in the module config file.  
"include" specifies classes to be included in the module if not excluded 
and its dependent classes are not included.

3. Change the wildcard syntax - "*" matches classes in the specified 
package and "**" matches classes in the specified package or any of its 
subpackages

4. Generate a new modules.pkginfo that lists all packages that split 
across multiple modules and also its dependencies with package-private 
access.  The "packages.splitdep" file I temporarily added is now removed.

When Chris and Vinnie reorganize the sources, this list should become 
smaller.   This will avoid needing to list specific classes in the 
module config files. 

5. I started to create a new modules.config file that only contains 
"include" and "exclude/allow" rules based on the classlist generated 
from modules.rootset.   There are some exclude rules that we should look 
into and determine if they should be included in that module if 
appropriate.
