Oskar Sundbom e403212ede Added nullopt and implicit construction to rtc::Optional
Both of these features are in std::optional and the lack
of them is making Optional use in WebRTC more cumbersome.

We are currently looking at using a more fully-fledged library
for some of our standard utility classes. This is merely a
stop-gap measure.
