    channelwidget: ensure that all channel labels have the same width
    
    pavucontrol.glade previously set the channel label width to 15
    characters, with the goal of making all channel labels have the same
    width. However, with some translations and font settings the configured
    width wasn't enough, so sometimes a label was wider than others, and
    that made the volume slider widths different too. If the volume sliders
    have different widths, it's very hard to visually compare the volumes of
    the channels.
    
    This patch removes the fixed width in pavucontrol.glade and solves the
    problem by finding the widest label and using that label's width with
    all labels.

    channelwidget: refactor to reduce repetition
    
    DeviceWidget and StreamWidget had some duplicate code to initialize
    ChannelWidgets. This patch moves some of the duplicated initialization
    code into ChannelWidgets to reduce repetition and to improve
    encapsulation.

    pavucontrol.glade: right-align channel labels
    
    The channel labels ("Front Left" etc.) that are adjacent to volume
    sliders used to be left-aligned, which meant that there was some empty
    space (depending on the text width) between the label text and the
    volume slider. Right-aligning the labels looks nicer.
