5f89225bc2 gstplugin: Don't stat plugins when building for UWP
When using GStreamer with Universal Windows Platform apps, dynamic
plugins can only be loaded by filename (without a path) using
gst_plugin_load_file() which will call into g_module_open().

On Windows, GModule calls LoadLibrary() on the filename, but with
UWP we need to use LoadPackagedLibrary() which is basically the same
as LoadLibrary(), except it looks only for DLLs (by name) that have
been packaged as assets with the app.

These assets are not files and cannot be accessed using normal file
APIs such as open() or stat().

The upstream glib merge request for adding LoadPackagedLibrary support
is: https://gitlab.gnome.org/GNOME/glib/merge_requests/951

NOTE: Whitespcae removal is to make gst-indent happy

5feff26624 plugin: plugin_load() must return a ref even if it was loaded already
Fix refcounting issue when plugin was loaded already.
gst_plugin_load() is supposed to return a ref, so it
must always return a ref.

This also fixes the gstplugin unit test on windows where
fork is not available and where test_load_coreelements()
would unref a plugin ref it didn't get and then mess up
the internal registry plugin list state for the next test,
in case where the test registry does not exist yet.

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

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.

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.

446b3e6ddc plugin: Don't do lossy shift on hash
In plugin is responsible for calculating a hash of the dependencies
in order to determine if the cache should be invalidated or not.
Currently, the hash combining method removes a bit of the original
have before combining with an addition. As we use 32bits for our hash
and shift 1 bit for each file and directory, that resulting hash only
account for the last 32 files. And is more affected by the last file.

Rotating technique (shifting, and adding back the ending bit), can be
use to make the addition non-commutative. In a way that different order
gives different hashes. In this case, I don't preserve this behaviour
because the order in which the files are provided by the OS is
irrelevant.

In most cases, the XOR operation is used to combine hashes. In this
code we use the addition. I decided to preserve the addition because
we make use of non-random hash ((guint) -1) in the algorithm for
matching files that are not really part of the hash (symlinks, special
files). Doing successive XOR on this value, will simply switch from
full ones, to full zero. The XOR used with whitelist has been preserved
as it's based on a fairly randomized hash (g_str_hash).

2759882379 introspection: add missing (nullable) annotations to return values
Support for (nullable) was added to G-I at the same time as nullable
return values.  Previous versions of G-I will not mark return values as
nullable, even when an (allow-none) annotation is present, so it is
not necessary to add (allow-none) annotations for compatibility with
older versions of G-I.

Next release versions until 1.0.0 will be 0.10.9X and
these will be release candidates. GST_VERSION_* will
nonetheless stay at 1.0.0.0.
