This will leak the delegate.  It isn't owned by BlimpClientContext.  Use a
std::unique_ptr and pass .get().  Make sure the destruction order is correct
(destroy BlimpClientContext before BlimpClientContextDelegate).

Done.

Put this up in the anonymous namespace block above or inline it if it's only
called once.

[steimel, 2016/09/27 17:35:01]

Done.
