c0c9a531ef event: Don't allow invalid SELECT_STREAMS event creation
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.

6adb6b478f seqnum: Never return a seqnum of 0, reset GST_SEQNUM_INVALID
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.

ebad8c0094 bin: iterate_sorted: Ensure sources are always returned last
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

a5e168071c plugin dependencies: fix 6cddce7663
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)

6cddce7663 plugin: API: GST_PLUGIN_DEPENDENCY_FLAG_PATHS_ARE_RELATIVE_TO_EXE
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

688d79033f gsturi: Fixed incorrect escaping of path as a generic string
The gst_uri_construct function was escaping the location string

changes the escape_string function mode to handle the path correctly.

I have deleted the escape_string function since it is no longer being

e7ede5a487 plugin: Unify static and dynamic plugin interface
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.

d108ed2251 gst: check non-null before dereference
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.

519d64881f Don't use deprecated g_object_newv()
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.

c173771ed2 gst: Use GstClockTimeDiff instead of GstClockTime as type for GST_SECOND and friends
They were (signed!) gint64 before because of G_GINT64_CONSTANT() already

efbacf1931 streamcollection: fix racy user-after-free
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.

allows the user to decide to retrieve a backtrace

82c871a8a3 gstutils: Fix a pad leak
When requesting a pad from a template and it's already linked, this
means it was a static pad. Since we only want to return an *available*
pad, we must return NULL ... but we must also remove the reference
we got from getting that static pad.

The "No need to unref" message (which wasn't true for quite some time)
dates back from the very very very first commit introducing the 0.10
features.

The caller might pass arbitrary data here that caused the error, and
trying to set invalid UTF-8 in a GstStructure causes it to be not set at
all. Later when trying to parse it, the field will not exist and the
return value will point to invalid memory. Prevent this by storing NULL
instead.

Also print a g_warning(), the caller should never ever do this to begin
with.

GstDynamicTypeFactory provides a way of registering a GType

type when the registry is loaded, and then automatically loaded
if the type is needed during caps parsing.

This allows using non-core types in pad templates, by loading a
registry feature to create the GType on the fly.

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Mathieu Duponchelle <mathieu.duponchelle@opencreed.com>

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

9fd2101b36 events: Implement the stream-group-done event
A new event which precedes EOS in situations where we
need downstream to unblock any pads waiting on a stream
before we can send EOS. E.g, decodebin draining a chain
so it can switch pads.

eead9cf827 message: Add redirect message
Redirection messages are already used in fragmented sources and in
uridecodebin, so it makes sense to introduce these as an official message
type.

d052ae63d8 element: fix GST_ELEMENT_ERROR() error code expansion
In some corner cases, the error 'code' part passed to
GST_ELEMENT_ERROR() is a valid define as well, in which
case it won't survive two levels of macro expansion, but
only one. Fixes:

oss4-sink.c: In function ‘gst_oss4_sink_open’:
error: ‘GST_RESOURCE_ERROR_0x00000002’ undeclared (first use in this function)
GST_ ## domain ## _ERROR_ ## code, __txt, __dbg, __FILE__,

which is from GST_ELEMENT_ERROR(el,RESOURCE,OPEN_WRITE,..)
and OPEN_WRITE happens to be defined to 2 here.

gst_structure_id_get() returns a new reference so the returned object is
actually (transfer full).

The unit tests was already unreffing the objects.

7a0f4422fa element: re-create threadpool after cleaning up tasks
We don't free this from gst_deinit() but from gst_task_cleanup_all(),
so more GStreamer API may be called. In particular makes unit tests
work again with CK_FORK=no.

40727d9c83 element: clean up thread pool from gst_task_cleanup_all()
This ensures that all async operations (started from gst_element_call_async())
have been completed and so there is no extra thread running.

Fix races when checking for leaks on unit tests as some of those
operations were still running when the leaks tracer was checking for
leaked objects.

Also fix some potential races with reading from the GstPoll before writing
