Please rview simple clean up of the modules build for javac

[Mandy Chung]

Hi Jon,

I made some minor fixes to the modules build per our discussion
of the new javac change to interface with the jigsaw resolver.

Webrev:
  http://cr.openjdk.java.net/~mchung/jigsaw/misc-cleanup/

1. make/modules/tools/Makefile to use JAVAC_CMD 
instead of HOST_JAVAC_CMD.  

- JAVAC_CMD is the hybrid javac building jdk and we should
  not need to use HOST_JAVAC_CMD.

2. make/modules/Makefile

- refactor the system module library creation as a new target
- when HOST_JAVAC_CMD is called to compile module-info.java,
  the default system module library is already created

3. modules.config and modules.group change

- this is a follow-up to the email thread about tools in 
  modules.config [1]
- javac, javap, javah, javadoc, and apt classes now live
  in its own module (each tool is a single module).
  Also, com.sun.tools.javac.Launcher class is moved to the
  deprecated.tools module.

Here are the dependencies among these langtools modules:

apt -> javac
apt -> jdk.langtools
javac -> jdk.langtools
javac -> jdk.logging
javadoc -> javac
javadoc -> jdk.langtools
javadoc -> jdk.xml
javah -> javac
javah -> jdk.langtools
javap -> javac
javap -> jdk.langtools

There is a dependency from JAXWS to apt:
   jaxws.tools -> apt

com.sun.tools.internal.ws.wscompile.WsgenTool -> com.sun.tools.apt.Main (apt)

Do you expect such dependency to apt?

- rmi.tools module is merged with the rmic module.


There exists a new rmic (sun.rmi.rmic.newrmic package) that
depends on javac and javadoc.  The new rmic is launched 
from rmic -Xnew option.
 
rmic -> javac
rmic -> javadoc

For your reference, the dependencies are:
sun.rmi.rmic.newrmic.BatchEnvironment    -> com.sun.javadoc.ClassDoc (javadoc)
sun.rmi.rmic.newrmic.BatchEnvironment    -> com.sun.javadoc.RootDoc (javadoc)

sun.rmi.rmic.newrmic.Main                -> com.sun.tools.javac.Main (javac)
sun.rmi.rmic.newrmic.Main                -> com.sun.tools.javadoc.Main (javadoc)
sun.rmi.rmic.newrmic.jrmp.JrmpGenerator  -> com.sun.javadoc.ClassDoc (javadoc)

sun.rmi.rmic.newrmic.jrmp.Util           -> com.sun.javadoc.MethodDoc (javadoc)
