Patch by Adrian Perez de Castro <aperez@igalia.com> on 2013-04-25
Reviewed by Philippe Normand.

Source/WebCore:

GStreamer has support for the Speex codec (http://www.speex.org).
Speex streams may be embedded in a Ogg container, or standalone.
The case of the Ogg container is already covered by the "*/ogg"
MIME types declared as supported by the GStreamer media playing
code, but for standalone streams to work, "audio/speex" has to
be added.

With this, and the needed GStreamer plugin installed, the GTK+
launcher is able to correctly play Speex streams served with
"Content-type: audio/speex".

LayoutTests:

Speex (http://www.speex.org) streams can be embedded into Ogg
Ogg containers, so add a check for it in the test case.
