Henrik Boström 81aab48878 Remove 'trackId' dependency in stats selector algorithm.
In preparation for the deletion of deprecated 'track' stats, the
stats selector algorithm needs to be rewritten not to use 'trackId'.

This is achieved by finding RTP stats by their SSRC, as obtained via
getParameters(). This unfortunately adds a block-invoke (in the sender
case the block-invoke happens inside GetParametersInternal and in the
receiver case the block-invoke is explicit at the calling place), but
it can't be helped and it's just once per getStats() call and only if
the selector argument is used.
