05a3da347b protection: Add a new definition for unspecified system protection
In some cases the system protection ID is not present in the contents
or in their metadata.
This define is used to set the value of the "system_id" field in GstProtectionEvent,
with this value, the application will use an external information to choose which
protection system to use.

Example: The matroskademux uses this value in the case of encrypted WebM,
the application will choose the appropriate protection system based on the information
received through EME API.

8983cce9f6 gst: GST_EXPORT -> GST_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

bda8440f1f protection: add function to filter system ids
gst_protection_filter_systems_by_available_decryptors() takes an array
of strings and returns a new array of strings filtered by the available
decryptors for them so the ones you get are the ones that you should be
able to decrypt.

92d3246f76 gst: mark symbols explicitly for export with GST_EXPORT
One omission: gst_allocator_sysmem_get_type() was
exported but never in any public header file.

bd9ea8d18f doc: Fix Since: marks
There was few Since: mark missing their column. Also unify the way
we set the Since mark on enum value and structure members. These
sadly don't show up in the index.

abdafb0d64 protection: add GstProtectionMeta to support protected content
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.

API: gst_buffer_add_protection_meta()
API: gst_buffer_get_protection_meta()
API: gst_protection_select_system()
API: gst_protection_meta_api_get_type()
API: gst_protection_meta_get_info()
