Bug 1297013 part.2 Implement some helper methods to log constants related to event handling r=smaug This patch implements some helper methods to log constants related to event handling. ToString(KeyNameIndex) and ToString(CodeNameIndex) converts the enum itmes to human readable string. They use WidgetKeyboardEvent's helper class which returns Unicode text. Therefore, this need to convert from UTF16 to UTF8. That's the reason why these methods don't return |const char*|. GetDOMKeyCodeName(uint32_t) returns DOM keycode name if it's defined. Otherwise, returns hexadecimal value. For generating switch-case statement, VirtualKeyCodeList.h shouldn't include ",". Therefore, this patch removes "," from VirtualKeyCodeList.h and append it at defining NS_DEFINE_VK. Additionally, the last item of enum and array should not end with ",". Therefore, this adds dummy last item at each of them. Finally, some of the keyCode values are shared between 2 keys. Therefore, it needs to support NS_DISALLOW_SAME_KEYCODE for switch-case generator. See the comment in the file for more detail. GetModifiersName(Modifiers) returns all modifier names included in the given value. MozReview-Commit-ID: 9i2ftFOTpDn
