Creates gstprotection in GStreamer core

In order to support some types of protected streams (such as those protected
using DASH Common Encryption) some per-buffer information needs to be passed
between elements.

This patch adds a GstMeta type called GstProtectionMeta that allows protection
specific information to be added to a GstBuffer. An example of its usage is
qtdemux providing information to each output sample that enables a downstream
element to decrypt it.
