Description Andrew Niefer

When the user specifies -vm pointing to an executable, then we should launch java in a separate process using the executable they specified like the old launcher did.

If the user doesn't explicitly specify an executable, then we will create the vm in the same process using JNI if possible.

This provides a better fallback story if we have problems (ie bug 167310, 168271).
This also allows using something like gcj on linux that doesn't have the jvm shared library.

This is now in HEAD and builds > I20070119
If -vm points at a library, we attempt to load the library using JNI invocation.  If it points at an executable, we fork a process with that exe like the old launcher did.

If no -vm is specified, the vm is found in the normal way and JNI is used on those platforms where it works well (win32, macosx, linux.x86, solaris).  On those platforms that don't work well (linux.ppc, linux.x86_64, aix) we fork the executable.
