        * PtraceByteBuffer.java: Moved over to frysk/sys.
        * PtraceByteBuffer.cxx: Moved over to frysk/sys/cni; fixes to use the new
        ptrace thread implementation - fixes #2783.
        * funit-threadexit.c: Removed race condition.
        * TestTaskTerminatedObserver.java: TestTerm now stops when the task dies
        as opposed to timing out.
        * TestLib.Java: Added print statement if event loop is not stopped.
        * Ptrace.java: Added methods for peek() and poke().
        * Ptrace.cxx: Added methods for peek() and poke().
        * Makefile.am: Builds with headers from inua.
