To make parser work with image having non-standard strides, plane
offsets or with padding between images.
For now, since element doesn't check for videometa, we can't directly
push buffers when these properties are set so it convert the frame
in the pre_push_buffer method to remove any custom padding.

Add a virtual method in rawparse to set buffer flags. This doesn't
use API from unreleased -base, since it defines GST_VIDEO_BUFFER_TFF
if it's not defined yet.

Add new plugin rawparse that contains a base class for raw data
parsers and the two elements audioparse and videoparse that can
be used to parse raw audio and video. These are inspired by the
old videoparse element which the new rawparse plugin deprecates.
