The Matroska muxer now allows WebVTT subtitle tracks to be written
while in WebM muxing mode.

WebVTT subtitle tracks have four kinds: "subtitles", "captions",
"descriptions", and "metadata". Each text track kind has a distinct
Mastroska CodecID and track type, as described in the temporal
metadata guidelines here:

http://wiki.webmproject.org/webm-metadata/temporal-metadata/webvtt-in-webm

When the stream has codec id AV_CODEC_ID_WEBVTT, the stream packet is
serialized per the temporal metadata guidelines cited above. The
WebVTT cue is written as a Matroska block group. The block frame
comprises the WebVTT cue id, followed by the cue settings, followed by
the cue text.  (The block timestamp is synthesized from the cue
timestamp.)

Some C runtime implementations deadlock when calling threading functions
on the atexit() handler.

Use a simpler wrapper similar to av_log to call the cleanup function
before exit.
