Instead, use a neat trick with union to ensure that we have a T only
when we're supposed to (and just a bunch of unused memory otherwise).
This is how std::optional behaves, so it makes sense for us to do the
same (and it's convenient, too, since we don't have to pay for the
default-constructed T, and we support types that don't have default
constructors).
Doing this became possible recently when we dropped support for MSVC
2013, which didn't support unions containing non-trivial types.

First two are unused, because the instance variables ratio_w_,
ratio_h_, and square_pixel_aspect_ratio_, are never modified after
initialization to 0 and false.
ARGB is believed to be unused, and the scaling logic
is probably not appropriate in any case.
Also delete corresponding helper functions in

refactoring of the code. In particular, it is not possible to separate
the application of the echo suppressor gain from the gain computation
and the comfort noise generation as all of these are partly included
in this method.

Objective-C applications using the data channel could crash when the following conditions were met:
- The application creates a data channel and sets a data channel delegate
- The delegate is deallocated but the application never clears it
When this happens, the dealloc method in RTCDataChannel would reset the delegate to nil. The setDelegate: method immediately returns if the new delegate value is the same as the old one. Since the old one is a weak reference, it becomes nil, and the DataChannelDelegateAdapter is not unsubscribed from the native channel before it gets deleted.
The fix removes the two optimizations, and instead subscribes the adapter to the native data channel at creation time - and unsubscribes it at dealloc time. This makes it very easy to reason about the lifetime of the subscription. Removing the optimization should have little effect on performance, as applications typically set the delegate when the channel is created.

In some cases, the DTLS ClientHello may arrive before the server's
transport is writable (before it receives a STUN ping response), or
even before it receives a remote fingerprint. If this packet is
discarded, it may take a second for a it to be sent again.
So, this CL caches it instead of dropping it, and feeds it into
the SSL library once the handshake has been started.
