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 commit 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. This commit adds a utility function to select a supported protection system from the installed Decryption elements found in the registry. The gst_protection_select_system function that takes an array of identifiers and searches the registry for a element of klass Decryptor that supports one or more of the supplied identifiers. If multiple elements are found, the one with the highest rank is selected. This commit adds a unit test for the gst_protection_select_system function that adds a fake Decryptor element to the registry and then checks that it can correctly be selected by the utility function. This commit adds a unit test for GstProtectionMeta that creates GstProtectionMeta and adds & removes it from a buffer and performs some simple reference count checks.
