• fix #146: "init
  segment fetch error" when browsers have cached data from v0.6.4 and
  before.
• fix #147: confusing
  nvr init failures when using very old versions of SQLite.
• fix #157: broken
  live view when using multi-view and selecting the first listed camera
  then selecting another camera for the upper left grid square.
• support --rtsp-transport=udp, which may work better with cameras that
  use old versions of the live555 library, including many Reolink models.
• send RTSP TEARDOWN requests on UDP or with old live555 versions; wait out
  stale sessions before reconnecting to the same camera. This may improve
  reliability with old live555 versions when using TCP also.
• improve compatibility with cameras that send non-compliant SDP, including
  models from Geovision and Anpviz.
• fix #117: honor
  shutdown requests when out of disk space, instead of retrying forever.
• shut down immediately on a second SIGINT or SIGTERM. The normal
  "graceful" shutdown will still be slow in some cases, eg when waiting for a
  RTSP UDP session to time out after a TEARDOWN failure. This allows the
  impatient to get fast results with ctrl-C when running interactively, rather
  than having to use SIGKILL from another terminal.
