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

/**
 * mozIStorageFunction is to be implemented by storage consumers that
 * wish to receive callbacks during the request execution.
 *
 * SQL can apply functions to values from tables. Examples of
 * such functions are MIN(a1,a2) or SQRT(num). Many functions are
 * implemented in SQL engine.
 *
 * This interface allows consumers to implement their own,
 * problem-specific functions.
 * These functions can be called from triggers, too.
