Add back function guard that checks the refcount in a read-only
operation first, and bail out without modifying the passed-in
memory if it's clearly not a valid mini object. Otherwise we
probably cause more harm than good. We keep the second sanity
check based on the 'real refcount' at the time of the unref
around for now too.

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.

Need to pass -DGST_DISABLE_DEPRECATED to avoid warnings when
testing deprecated API such as gst_uri_construct().
Also remove #ifndef GST_DISABLE_DEPRECATED guard from header
file, we don't use those any more for functions, the
GST_DEPRECATED_FOR macro is enough.
The gst_uri_construct function was escaping the location string
as a generic uri string. This is incorrect since the slash('/')
characters are reserved for use in this exact case. The patch
changes the escape_string function mode to handle the path correctly.
I have deleted the escape_string function since it is no longer being
used and have created a unit test for the function. I have also
deprecated this function in favour of the GstUri API.

This is something bindings can't handle and it causes leaks. Instead
move the ref_sink() to the explicit, new() constructors.
This means that abstract classes, and anything that can have subclasses,
will have to do ref_sink() in their new() function now. Specifically
this affects GstClock and GstControlSource.

If a function takes a floating reference parameter, it should also be
sinked in error cases. Otherwise the function behaves differently
between error and normal cases, which is impossible for bindings to
handle.

If a function takes a floating reference and sinks it, it should also do
that in error cases. I.e. call ref_sink() followed by unref().
Otherwise the reference counting behaviour of the function will be
different between the good and the error case, and simply inconsistent.

Can't use a #ifndef GST_DISABLE_DEPRECATED guard around deprecated
functions any more, as they won't get exported then. Besides, we
get a nicer error message from the compiler telling us what function
to use instead this way.
This is a meta that generically allows to attach additional reference
timestamps to a buffer, that don't have to relate to the pipeline clock
in any way.
Examples of this could be an NTP timestamp when the media was captured,
a frame counter on the capture side or the (local) UNIX timestamp when
the media was captured.

This is useful for integration with other event loops that work by
polling file descriptors. G_IO_IN will always be set whenever a message
is available currently.

This patch changes the entry point of each plugin in order to unify the
interface for static and dynamic plugin. What we do is replace the
current static plugin interface and extend the dymamic one. The plugin
entry was a C structure, name "gst_plugin_desc". With this patch, the
interface is now:
GstPpluginDesc *gst_plugin_<name>_get_desc(void);
The reason we change the C structure into function, is that it is
potentially more common to have function pointers, avoiding possible
binding language limitation. Additionally to that. This change prevents
the symbols from clashing between plugins, allowing to build once the
plugin (assuming you have -fPIC).
On the plugin loader side, we symply derive the shared object basename
to extract the plugin name. If this symbol is not found, we fallback to
gst_plugin_desc for backward compatibility.
This has one side effect, which is that the shared objects now need to
be named after their plugin name. This is generally the case with few
exceptions. The benifit of this limitation is that you can control the
gst_plugin_<name>_desc clash at file level.

It is possible to use gst_deinit() without registering the base
classes. For example, when using gst_init_get_option_group() and
call the program with an invalid parameter. In that case,
gst_deinit() will lead to a segmentation fault, since there is a
dereference to a pointer that is null.
This patch validates if the type is non-null before dereferencing
it.
