checking whether we already were in the target GstPadMode was being
done too early and there was the risk that we *would* end up
(de)activating a pad more than once.
Instead, re-do the check for pad mode when entering the final pad
(de)activation block.

Add convenience API that iterates over all pads, sink pads or
source pads and makes sure that the foreach function is called
exactly once for each pad.
This is a KISS implementation. It doesn't use GstIterator and
doesn't try to do clever things like resync if pads are added
or removed while the function is executing. We can still do that
in future if we think it's needed, but in practice it will
likely make absolutely no difference whatsoever, since these
things will have to be handled properly elsewhere by the element
anyway if they're important.
After all, it's always possible that a pad is added or removed
just after the iterator finishes iterating, but before the
function returns.
This is also a replacement for gst_aggregator_iterate_sink_pads().

Asking to select no streams makes no sense and can create various
issues.
If one doesn't one any stream it should deactivate (or not use) the
element in question.
Various plugins use the value of '0' as an invalid seqnum value
(qtdemux for matching duplicated seek events, for example). Make
that behaviour explicit, create a GST_SEQNUM_INVALID value,
and ensure gst_util_seqnum_next never returns it.
For linked elements, the resulting gst_bin_iterate_sorted() will
properly return elements from sink to sources.
If we have some elements that are not linked, we *still* want to
ensure that we return:
* In priority any sinks
* Last of all any sources
* And in between any element which is neither source nor sink
For this to work, when looking for the next candidate element,
not only check the degree order, but if there are two candidates
with the same degree order, prefer the non-source one.
Amongst other things, this fixes the case where we activating a
bin containing unlinked sources and other elements. Without this
we could end up activating sources (which might start adding pads
to be linked) before other (to which those new source element pads
might be linked) are not activated

There were a few errors:
* The plugin scanner now accepts executable path as an argument.
In case it is NULL, argc == 2
* We find the executable path in init_pre instead of gst_init,
allowing this to work when gst is initialized through the
option group (eg gst-inspect)
* There was a semi-colon missing in the __APPLE__ #ifdef
When a plugin declares a dependency using this flag, all the
relative paths are considered to be relative to the path of
the main executable.
We try to determine the path of the executable portably,
with implementations provided for Linux, Windows and Mac.
If retrieval of the path fails, we will not detect changes.
In order for the main executable path to be the same when
scanning a plugin in a child process, a new variable is
exposed in gst_private.h, _gst_executable_path

If multiple probes are set on a pad and one probe returns either
GST_PAD_PROBE_HANDLED or GST_PAD_PROBE_DROPPED we need to stop
calling the remaining probes.

for vararg parameters. Vararg functions are not introspectable anyway,
so might just as well mark them as '(skip)' while we're at it.
gstutils.c:2611: Warning: Gst: invalid "transfer" annotation for <varargs>: only valid for object and GVariant types
Without the former, event changes (e.g. setting a pad offset) does not
take effect for the current buffer but only for the next one. Without
the latter, non-blocking event probes would not see any updated events
yet.
This stores debug logs in memory per thread and uses up to a
configurable amount of bytes per thread for the logs. Inactive threads
are timed out after a configurable amount of time.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=743062
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.
https://bugzilla.gnome.org/show_bug.cgi?id=747990
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.
https://bugzilla.gnome.org/show_bug.cgi?id=747990
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.

Use g_object_new() instead which nowadays has a shortcut for the
no-properties check. It still does an extra GType check in the
function guard, but there's a pending patch to remove that
and it's hardly going to be a performance issue in practice,
even less so on a system that's compiled without run-time checks.
Alternative would be to move to the new g_object_new_properties()
with a fallback define for older glib versions, but it makes the
code look more unwieldy and doesn't seem worth it.
Fixes deprecation warnings when building against newer GLib versions.

They were (signed!) gint64 before because of G_GINT64_CONSTANT() already
and they are actually used in signed calculations.
With this change we at least ensure that an integer type of the correct
size is used for GI (it was using gint before).
The issue happens when the structure is printed by the logging
subsystem: the object is included in the log, and this will cause the
full object printout to be done there. However, after dispose, the queue
was already cleared, so the access to it (to print the object) would
assert, as the queue was already freed. The patch changes it so that the
queue is merely empty, and only freed in _finalize.

A paramspec validation should modify the content to match what the spec
requires and return TURE if a modification happened. This previous
implementation would only fix the first element of the array and return.
It was also return TRUE for empty array, while no modification was
needed.
