Integrate NaCl debugger with Chrome/Webkit Developer Tools

by Maxim Ermilov for Chromium

Native Client enables performance-sensitive code, written in C++ or other low-level languages, to be safely called from JavaScript. Applications can be written in a combination of JavaScript and native code. The goal of this project is to simplify and unify the debugging experience for this kind of hybrid application. Developers could use the Chrome developer tools window to step through NaCl code and view symbols.
