If the packet starting at i_pagepos is larger than a page, i_input_position
will point to the last of those pages and we need to seek to the first one.

If the granulepos is negative we need to pagein the page nevertheless
because it might contain a packet that is continued on the next page. Also
we want to return the position of the first page containing the packet.

The edge detection filter uses the Sobel operator to detect and highlight
edges in a frame. In order to successfully detect an edge, the image must
first be converted to gray scale (because Sobel is a gray scale operator) and
then have a slight Gaussian blur applied to it. We do this because Sobel is a
noisy operator and the Gaussian blur reduces this noise.

Implements the interface to provide the VLC pictures
from vout mapped to GstBuffers, along with per video
plane stride/offsets info, to the upstream gstreamer
video decoder. If the stride/offsets info of the vlc
pictures (created by vout) matches the video decoder's
expectations, the decoder will directly decode into
the vout allocated pictures, enabling zero-copy. Else
it will continue to use it's own bufferpool

The setting vbi-position does not appear on global level. Thus the regarding
variable callback is never invoked and therefore can be removed.

This commit adds an option to the ZVBI settings to select the Teletext
Presentation Level which is used for decoding. Thus one can switch to a lower
level in case of problems or can compare the rendering of a page at different
levels. The default value is Level 3.5, which already has been used each time
for decoding here.
