Bug 1293117 (part 5) - Change many NS_METHOD occurrences to NS_IMETHOD. r=froydnj. This patch makes the following changes on many in-class methods. - NS_METHOD F() override; --> NS_IMETHOD F() override; - NS_METHOD F() override {...} --> NS_IMETHOD F() override {...} - NS_METHOD F() final; --> NS_IMETHOD F() final; - NS_METHOD F() final {...} --> NS_IMETHOD F() final {...} Using NS_IMETHOD is the preferred way of marking in-class virtual methods. Although these transformations add an explicit |virtual|, they are safe -- there's an implicit |virtual| anyway because |override| and |final| only work with virtual methods.
