Summary:
Prior to this diff we would clone out an entire flow control's worth of data from the writebuffer and then clone out a smaller portion of that to write into the packet builder. This is extremely wasteful when we have a large flow control window.
Additionally we would always write the stream data length field even when we are going to fill the remainder of the packet with the current stream frame. By first calculating the amount of data that needs to can be written and writing the header, we can now omit the data length field when we can fill the whole packet.

Summary: These were changed to varints. To support this we need to do some extra horrible version plumbing. I don't want to keep this long term but it works for now.

Summary:
The plan is to not treat probing frame as simple frame, but that is not
going to happen soon.
