title: how to get current debugging process's info in __lldb_init_module?
body: <p>the lldb extension script's entrypoint is:</p>
  <pre class="lang-py prettyprint-override"><code>def __lldb_init_module(debugger, internal_dict):
  </code></pre>
  <p>however, when I access <code>debugger.target</code>, it's <code>No Value</code>.</p>
  <p>lots of tutorial shows how to use <code>SBDebugger.CreateTarget</code> to create new target and process, but now I'm debugging from IDE's debug workflow, I don't think I should create target myself, I just want to get(or wait for) the current debugging process(launched by IDE) and target, then invoke some commands as <code>pro hand -p true -s false SIGPWR</code>.</p>
  <p>so the problem is how could I access the <code>current target</code> in the none-standalone-launch mode?</p>
