Bug 1513039 - part5 : log warning when autoplay is blocked. r=cpearce,karlt Wrap 'nsContentUtils::ReportToConsole()' to reduce necessary input parameters and call it when we need to log error or warning message. Show the warning when autoplay is blocked. For web audio, this restores the console messages removed in part4 and also reports the same message when the AudioContext is blocked in the constructor.

 * mozIStorageFunction is to be implemented by storage consumers that

 *
 * 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.
