Previously, the font_scale parameter available for the video_mute_banner/video_banner_text
conference channel variable would only accept integer values. It now can accept float
values for more fine grained control, eg:

  <action
    application="set"
    data="video_banner_text={font_scale=.75}Banner Text"
  />

Add params to set min_font_size and max_font_size for video banners.

The hard-coded defaults of 5/24 for min/max font size don't always look good
depending on the layout use case. This adds min_font_size and max_font_size
params for more fine-grained control, eg:

  <action
    application="set"
    data="video_banner_text={min_font_size=8,max_font_size=14}Banner Text"
  />

Erroneous DLSR in received RTCP report could
cause RTT to be negative (RTT = A - DLSR - LSR).
Add check for this and prevent corruption
of statistics and estimations (estimator code used
bad RTT values).
