    flacparse: Make bitrate estimation more accurate

    This implements the get_frame_overhead() vfunc so that baseparse can
    make more accurate bitrate estimates.

    aacparse: Fix bitrate calculation

    This patch adds the get_frame_overhead() vfunc so that baseparse can
    accurately calculate the min/avg/max bitrates for aacparse.

    Note: The bitrate was being incorrectly calculated for ADTS streams
    (it's not in the header as the code suggests).

    audioparsers: Add bitrate calculation to baseparse

    This makes baseparse keep a running average of the stream bitrate, as
    well as the minimum and maximum bitrates. Subclasses can override a
    vfunc to make sure that per-frame overhead from the container is not
    accounted for in the bitrate calculation.

    We take care not to override the bitrate, minimum-bitrate, and
    maximum-bitrate tags if they have been posted upstream. We also
    rate-limit the emission of bitrate so that it is only triggered by a
    change of >10 kbps.
