Patch introducing javac.fork flag

I cannot build NetBeans with:

$ ant clean build

command in root directory. Whenever I try the build fails on j2ee.dd module with out of memory error. My setup:

$ java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)
$ ant -version
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0
Apache Ant(TM) version 1.9.3 compiled on April 8 2014


If I switch to j2ee.dd after the build fails and compile the module separately, then the build succeeds. This leads me to following suggestion: Let's move the build into separate process. I can confirm that with attached patch, the compilation succeeds.

As the proposed fix introduces an API change in apisupport.harness I am requesting a review. As I am changing CustomJavac class introduced by Jesse, I am CCing him.

No objections so far, I'd like to integrate tomorrow, then.
