got JNI; but only just :-)

[Andrew Cagney <cagney at redhat dot com>]

FYI,

I've just pushed changes to frysk's build system that add the ability to 
build JNI code vis:

- automatically generate required jni headers
- compile */jni/*.cxx files into a separate shared object

while at the same time continuing to build the existing CNI code.  By 
being able to build/run both side-by-side we'll hopefully help to ease 
the migration pain.

In the frysk-sys directory, I've also added stub C++ JNI functions (they 
just throw an exception) for all the required native methods.  You can 
invoke TestRunner, but using JNI and these stub-functions, with the 
script JniRunner vis:

$ ./JniRunner
Exception in thread "main" java.lang.RuntimeException: 
../../frysk/frysk-sys/frysk/config/jni/Config.cxx:Java_frysk_config_Config_createBuildConfig 
not implemented
       at frysk.config.Config.createBuildConfig(Native Method)
       at JniRunner.main(JniRunner.java:57)

(Did I mention that all the JNI functions were stubs and just threw 
exceptions? :-)

Next I'm going to work my way through frysk.config, frysk.rsl, and 
frysk.sys.

The lib/* libraries are an opportunity waiting to happen :-)
