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()

1dd72f56ea debugutils: nicer printing of caps features
Only print interesting caps features, don't
append (memory:SystemMemory) to all caps,
which makes them much more unwieldy and
harder to read. Also use internal function
to get caps features so that our printing
has no side effects on the caps.

da7847d1ad message, bus: fix async message delivery
Async message delivery (where the posting thread gets blocked
until the message has been processed and/or freed) was pretty
much completely broken.

For one, don't use GMutex implementation details to check
whether a mutex has been initialized or not, esp. not
implementation details that don't hold true any more with
newer GLib versions where atomic ops and futexes are used
(spotted by Josep Torras). This led to async message
delivery no longer blocking with newer GLib versions on
Linux.

Secondly, after async delivery don't free mutex/GCond
embedded inside the just-freed message structure.

Use a new (private) mini object flag to signal GstMessage
that the message being freed is part of an async delivery
on the bus so that the dispose handler can keep the message
alive and the bus can free it once it's done cleaning up
stuff.

81d613694c clock: Improve slaving regression.
Add domain checks for the input values, and a variable precision
calculation that loops if necessary to ensure we never overflow
accumulators and then silently produce garbage results.

Make the (non-public) linear regression function available for
unit testing by putting it in a separate source file the test
can include. Add a unit test that the new regression function
produces sensible results for several inputs taken from real-world
captures.

7477b25df5 caps: Add new data type for handling caps features to the caps
These are meant to specify features in caps that are required
for a specific structure, for example a specific memory type
or meta.

Semantically they could be though of as an extension of the media
type name of the structures and are handled exactly like that.

93a2b6e9b3 value: use datetime serialise/deserialise functions for datetimes

5a6be2201d datetime: fix compare function
Take into account that not all fields might be valid (though they
are valid in the GDateTime structure). But we should just return
unordered if the set fields don't match. Also, don't check
microseconds when comparing datetimes, since we don't serialise
those by default if they're available. This ensures date times are
still regarded as equal after serialising+deserialising.

2c532aa821 toc: put toc directly into event/message/query structure
Now that TOCs are refcounted and have a GType, we can just
stuff a ref of the TOC directly into the various toc
event/message/query structures and get rid of lots of
cracktastic GstStructure <-> GstToc serialisation and
deserialisation code. We lose some TOC sanity checking
in the process, but that should really be done when
it's being created anyway.

5b4417ff9e pluginfeature: make GstPluginFeature structure private
Make GstPluginFeature opaque until we have time to

GstTypefindFactory derive from it, and they are

19d4c0ba73 plugin: make GstPlugin object structure opaque for now
There's no reason anyone would want to derive from this, so
just make opaque until we manage to make all the private bits
private properly (which I'm not doing right now because it's
more invasive and I have registry modifications locally which
touch all that code as well).

ac40ab45b3 info: make _gst_debug_init() private for now
This was a FIXME for 0.11. I guess a case could be made to keep it around
separately for apps or libraries that only want to use GStreamer's debugging
system, but it seems more likely they'd just copy the two source files into
their own tree if the case. Also, things like types wouldn't be initialised
without gst_init(). We can still make it public again if anyone needs it,
but then we should make it a proper function and not hide it behind
underscores.

f3b0d3cdbe init: add _get_type() functions
Remove gst_mini_object_register() and add a GST_DEFINE_MINI_OBJECT macro to

Rename some _init method to _priv_*_initialize() like the rest of them.
