This prevents the ugly hack where the text_sink pad template
was only added for textoverlay but not for the subclasses.
Also makes this work with the core change that made
subclasses inherit the templates of their parent class.
Pango is not reentrant. Use a class wide mutex to protect pange use in
gst_text_overlay_render_pangocairo(). This works reliable in contrast to the
hack in my previous commit.
Fixes Bug #412678
Rather than only left, right, top, etc, allow for horizontal and vertical
positioning on a scale from 0 to 1.
Also cater for configuring rendered text color.
Fixes#624920.

* ext/pango/gsttextoverlay.h:
Add property to configure waiting for text on the textpad or not, with
the default behaviour being the old one (always wait for text before
rendering the video). This default behaviour is usually not the best one
because the text stream can very sparse and could require queueing a lot
of video.
Fix the flushing and EOS handing so that we don't mix up their meaning.

API: add "line-alignment" property (#459334). Add gtk-doc blurb for
"silent" property so there's a Since tag in the API reference.

Some textoverlay fixes: for one, in the video chain function,
actually wait for a text buffer to come in if there is none at the
moment and there should be one; also, deal more gracefully with
incoming buffers that do not have a timestamp or duration; discard
text buffer when not needed any longer. Fixes#341681.

second batch :
remove ',' at end of enums as they could confuse older gcc, foreign compilers (forte) and gtk-doc
