Add <memory> include?

[kwiberg-webrtc, 2016/02/17 03:06:30]

No, the .h file already does that.

[aluebs-webrtc, 2016/02/17 03:15:59]

I brushed up my style-guide knowledge and you are right, explicit includes
doesn't apply to cc files and their related headers :)

[kwiberg-webrtc, 2016/02/17 03:25:31]

I'd gloat, except I didn't know better either until a couple of days ago when
hlundin@ complained I was adding an unnecessary #include <memory> to a .cc file
in another of these CLs...
