Initialize the {@link #debugger}. You can specify a customized {@link SmackDebugger}
by setup the system property <code>smack.debuggerClass</code> to the implementation.

@throws IllegalStateException if the reader or writer isn't yet initialized.
@throws IllegalArgumentException if the SmackDebugger can't be loaded.
