The Telemetry::AccumulateTimeDelta function reports in milliseconds but I had
assumed seconds when I added the hostname obfuscation ICE duration histogram.
This change adjusts the "high" value accordingly.
With the telemetry we've collected to date, 60% of the values are below 600
milliseconds, so I think that setting a high value of 30 seconds should be
sufficient even if there is a long tail. Since this does not change the data
being collected, no additional data-review is required, but it does require
renaming the key.

Bug 1568101/D40532 captures the input timestamp and uses it in the resolve
function. However, there could be multiple encoded frames returned (e.g.,
for Drain()), and all of them will get the same captured timestamp. Read
back the timestamp from encoded data makes sure every frame gets the right
value. Also convert it for EncodedImage::_timeStamp uses different unit.

Freeing the conduits when the transceiver is stopped releases all of the
associated webrtc.org objects which results in substantial memory savings.
On my system, with an opt+debug build and 200 stopped transceivers, I see
373.17 MB of memory use in the content process without this patch, and
158.93 MB of memory use with this patch applied.
Going further and calling Shutdown_m as part of Stop() reduces the memory
use to 157.98 MB, which seems like a marginal improvement at the cost of
a much larger risk of introducing bugs.

This adds a mObfuscateHostAddresses member and uses it to control whether or
not peer reflex candidates are redacted. It is only necessary to keep track of
signaled addresses to support redacting peer reflex candidates, so there is no
need to store them if host address obfuscation is disabled.

In InitDecode it is possible for mDecoder to be null if the CreateDecoder call
fails, in which case an error code is returned. Release is called by
GenericDecoder::~VCMGenericDecoder regardless of whether InitDecode succeeds, so
we need to check if mDecoder is null in Release.

In OnIncomingFrame() we check if the capture has started by calling
CaptureStarted() which holds a lock. If StopCapture() is called on the
control thread after we check CaptureStarted() it is possible that
_captureCapability will be zeroed out prior to frame being delivered because
the lock has been released. This would result in an unknown video type in
CalcBufferSize() and trigger an assertion there. This creates a local copy of
_captureCapability with the lock held to ensure it is not zeroed out when the
frame is delivered.

In order to encode video frame, we have to convert `webrtc::VideoFrame` to gecko's video data, and then send this YUV-based video data to the encoder.
The encoder won't return an encoded frame everytime when we call its `encode()`, so we have to wait until there are valid samples added to `mEncodedFrames`.
Then, convert the `MediaRawData` to `webrtc::EncodedImage` and provide an NAL entries list to indicate where the NALs are in the encoded bytes stream and how large they are. We would send those data back
to the consumer of the encoder via calling a callback function `OnEncodedImage()`.

`RefCountedWebrtcVideoEncoder` is a generic interface which supports refcounting, using that can ensure the encoder is always alive even if using it in an async task.
So now both `WebrtcGmpVideoEncoder` and `WebrtcMediaDataEncoder` would inherit from `RefCountedWebrtcVideoEncoder`.
We can use `WebrtcVideoEncoderProxy` to wrap them and return `WebrtcVideoEncoderProxy` for the use in the WebRTC pineline.
