Currently there is a hard limit for the estimated captured frame
interval of 45ms. As the encoder utilization is calculated as
(input frame interval)/(encode time), overuse signals can be triggered
even though there is plenty of time to go around if the fps is low.
However, in order to avoid falsly estimating low encode usage in case
the capturer has a dynamic frame rate, set the frame interval based on
the actual current max framerate.

In the case of H264 we can't know which packet that is the fist packet of a
frame. In order to avoid creating incomplete frames we keep track of which
packets that we haven't received, and if there is a gap in the packet sequence
number leading up to this frame then a frame wont be created.

Prior to this change, the SimulcastEncoderAdapter would destroy and create
encoders whenever it is being reinitialized. After this change, the
SimulcastEncoderAdapter will cache the already allocated encoders, and reuse
them after reinitialization.

Since the RtpStreamId and RepairedRtpStreamId extensions can have variable
length, it makes no sense for them to have a constant valueSize field.
The header length calculation in RtpHeaderExtensionMap needed to be changed
for this because it previously worked with the assumption that all header
types have a constant size. Now it's the caller's job to specify the length
of the extensions that it might use.
