Alan, Kelly,

It in fact contains 2 fixes:
1. integrate the latest jdk modularity fixes from jigsaw repos
- add modules target in the top forest makefile [1]
- support SKIP_BOOT_CYCLE=false modules build [2]
- fix a couple of bugs in the launcher [3]
- add JDK_HOST_PATH to support cross-architectural modules build [4]
- cleanup on the modules.config and module names in makefiles
2. incremental modules build support to ease jdk development
- the changes are mainly in make/modules and
make/tools/classanalyzer files.
The modules build includes two main steps:
a. run the class analyzer tool to assign classes and resources in
the jdk modules and analyzes their dependencies
b. modularize the build output and create a module library
containing the jdk modules
I created a new tool com.sun.classanalyzer.Modularizer to do the files
copying in step 2. Both ClassAnalyzer and Modularizer will process
classes/resources files that are updated since the previous build. The
jdk build will update a new file submodules/.modules.update if classes
are recompiled, a library is rebuilt, or a file is installed in the jdk.
The modules build will use the timestamp of .modules.update file to
determine if it should do an incremental or do a full modules build.
Thanks
Mandy
