Improve wording of comments and description

Replace an existing ES with another without disrupting the client. It
can be used in combination with VLM. Here is an example vlm command file:

  # VLC media player VLM command batch
  # http://www.videolan.org/vlc/

  # MPEG-TS stream
  new ts broadcast enabled
  setup ts input "file:///<path_to_some_file_to_play>"
  setup ts output #duplicate{dst=bridge-out{id=1},select=video,dst=bridge-out{id=0xa3},select=audio}
  setup ts loop

  # Mic input
  new mic broadcast enabled
  setup mic input "alsa://"
  setup mic output #transcode{acodec=mpga,ab=192,channels=2}:bridge-in{id-offset=0}:select{disable=0}:setid{id=0,newid=0xa3}:autodel:std{access=udp,mux=ts,dst=127.0.0.1:1234}

  # Fire it up
  control ts play
  control mic play

If allocating fails, then graciously fail instead of crash.

Graciously fail if snd_pcm_start() returns an error.

The framerate as specified by the user or detected by the v4l2 access input was
overwritten by the rawvideo decoder. The module did not specify:

	es_fmt.video.i_frame_rate
	es_fmt.video.i_frame_rate_base

Their default values are 0. The rawvideo decoder detects that there is no framerate
specified and resorts to its own default (fps 25.0). Through setting framerate and
framerate_base in the v4l2 es format the correct fps is communicated to vlc core.

The framerate reduction code is not needed. If the user did not set
the requested framerate, then the v4l2 module asks the driver for its
default value. When fps is specified by the user then that one is used.

here I rename „VLC grotuvas“ to „VLC leistuvė“ according to
recommendations (because „grotuvas“ is better word for technical device
and „leistuvė“ is better for software application)
