e9a6cafa13 basetextoverlay: fix buffer leak in chain function 
If we don't consume the buffer by passing its reference to
overlay->text_buffer then we need to unref it.

Fix a leak with validate.file.playback.fast_forward.test5_mkv
when running inside Valgrind.

b247001aa9 textoverlay: fix disappearing text with high deltax 
When deltax is large enough to cause the text to push past the
width of the frame, it would disappear due to a bug in setting
the layout width.

While there, fix a log printing an incorrect width to set.

46e727ebde Revert "basetextoverlay: Fix segfault when overlay outside the frame" 
This is not correct. overlay->silent is a property and we
should not just flip the property forever because one text
we render is outside of the frame. The next one might not
be, the positioning properties can be changed after all.

The lower layers should handle clipping, and now do.

This reverts commit 1cc311156c.

a003423bc3 Revert "basetextoverlay: segfault when xpos >= video size" 
This is not right, even if it might avoid a crash. We don't
want to just set xpos/ypos to 0 in those cases. Clipping
should be done properly, see bug #739281 for that.

This reverts commit 900d0267d5.

900d0267d5 basetextoverlay: segfault when xpos >= video size 
When the xpos is given as greater than or equal to the video size,
we get a segfault, due to improper condition.
Hence adding proper conditions.

1cc311156c basetextoverlay: Fix segfault when overlay outside the frame 
When the textoverlay is set outside the video frame by deltax or deltay the
calculation segfaults, but it is also  unnecessary since it doesn't need to be
displayed. So we should clip the text.

3ecb8bea22 basetextoverlay: Do not fail the negotiation if query fails 
The allocation query failure doesn't mean that the negotiation
has failed as the element can allocate buffers itself.

Instead, only fail if the pads are flushing and the allocation
query failed.

76ce112994 basetextoverlay: schedule reconfigure on source pad when negotiation fails 
The source pad might be flushing while negotiating, resulting in
set_caps or the ALLOCATION query failing. In this case set the
reconfigure flag on the source pad so that negotiation is retried on the
next buffer.

501a295fa1 basetextoverlay: remove unneeded cairo transparence setting 
he code here:

http://cgit.freedesktop.org/gstreamer/gst-plugins-base/tree/ext/pango/gstbasetextoverlay.c#n1554

should make transparent the box that contains the text, I think this code is
not correct, it should be:

if (overlay->want_shading) {
    double alpha = overlay->shading_value / 255.0;
    cairo_paint_with_alpha (cr, alpha);
  }

however I think this code could be removed, we already do a shaded background,
why shade the box behind the text with cairo too? only one shading is needed so
we must shade with cairo or with methods like these:

http://cgit.freedesktop.org/gstreamer/gst-plugins-base/tree/ext/pango/gstbasetextoverlay.c#n1642

not both

a65b307349 basetextoverlay: properly fallback to non-overlay caps 
When downstream claims to accept the overlay meta but fails to
provide it in the allocation query, properly fallback to setting
a new caps without the overlay meta as that is not going to be used.

Only do this if the original caps doesn't have the overlay already,
otherwise there isn't much that can be done.

e783a366cb textoverlay: Don't hold any mutexes while calling negotiate 
It's not done in any other code calling negotiate and will cause deadlocks
as it is sending events and queries in the pipeline.

Specifically this pipeline was deadlocking:

5fc94da399 textoverlay: remove code that can't be reached 
If this code could ever be reached, it would leak

a080c0ebbf basetextoverlay: rework caps negotiation 
Make textoverlay negotiate caps more correctly.

1) Check what caps we received in the video-sink
2) If it already has the overlay meta -> use it directly
3) If it doesn't, textoverlay try adding the overlay meta and using it,
   if downstream doesn't support it, just use what is received in the
   video-sink
4) Check if the allocation query also supports the meta to enable
   really using it

Before it wasn't really doing renegotiation of any kind, just
re-checking if it should use the overlay meta or not

Also had to update the caps in the test as memory:SystemMemory seems
to be required when you use a caps feature otherwise intersection/subset
checks will fail.

ec7724c095 basetextoverlay: use correct segment for text 
video time uses the 'segment' and the text time should use
the 'text_segment'.
