onvifmetadata: removing encoding field
...
The encoding of ONVIF metadata is always UTF-8. ONVIF metadata may
or may not be encoded with gzip, but we don't see a use case for
transporting compressed ONVIF metadata between elements for now.

onvifaggregator: refactor, expect parsed metadata
...
The aggregator was consuming meta buffers too greedily, causing
potential interleaving starvation upstream. Refactor to consume
media and meta buffers synchronously
Also expect parsed=true metadata caps (requiring an upstream
onvifmetadataparse element).

onvifaggregator: refactor to support duration-less media buffers
...
For instance when dealing with a variable framerate media stream,
input media buffers may not hold a duration, in which case we try
to calculate one by waiting for the following buffer.
