Bug 784841 - Part 2: Implement sandboxing for Python build files; r=ted,glandium This is the beginning of Mozilla's new build system. In this patch, we have a Python sandbox tailored for execution of Python scripts which will define the build system. We also have a build reader that traverses a linked set of scripts. More details are available in the thorough README.rst files as part of this patch. * * * Bug 784841 - Part 2b: Option to not descend into child moz.build files; r=ted

/**
 * An asynchronous SQL statement.  This differs from mozIStorageStatement by
 * only being usable for asynchronous execution.  (mozIStorageStatement can
 * be used for both synchronous and asynchronous purposes.)  This specialization
 * for asynchronous operation allows us to avoid needing to acquire
 * synchronization primitives also used by the asynchronous execution thread.
 * In contrast, mozIStorageStatement may need to acquire the primitives and
 * consequently can cause the main thread to lock for extended intervals while
 * the asynchronous thread performs some long-running operation.

   * 'params' provides a magic JS helper that lets you assign parameters by
   * name.  Unlike the helper on mozIStorageStatement, you cannot enumerate
   * in order to find out what parameters are legal.
   *
   * This does not work for BLOBs.  You must use an explicit binding API for
   * that.
   *
   * example:
   *  stmt.params.foo = 1;
   *  stmt.params["bar"] = 2;
   *  let argName = "baz";
   *  stmt.params[argName] = 3;
