RFR: JDK-8244093 Move all IDE support into coherent structure in make directory

[Bradford Wetmore]

Jan,

What is your current recommended technique to use NetBeans to 
build/edit/test OpenJDK for normal OpenJDK library developers?

After many versions of Netbeans, my current setup is to:

1.  Do an external "exploded" build

2.  Run Netbeans, open the src/java.base module project and any other 
modules needed.

3a. For OpenJDK test files under test/jdk:  Open the java.base test dirs 
for the JTREG tests I need.  Then run "Debug Test File" to invoke JTREG

3b. For tests not in test/jdk (external to repo):
         1.  Add a Java platform for the exploded-build
         2.  Create a project, assign the platform
         3.  Create standard Debug project.

4.  For incremental builds, edit source file, build from the command 
line something like:

     % make JDK_FILTER=java/security java.base-java-only

Is there another way of working I'm missing?

Things have been really solid for me lately (OpenJDK/JTREG plugins not 
needed), thanks for all your hard work on this.

Cheers,

Brad
