d5c0b3311b bufferlist: Don't chain up finalize to the parent class

d41997040b gst: make _get_type() in gst/* thread safe
This is not really necessary here because everything is
initialized from gst_init() already but using G_DEFINE_TYPE()
removes some copy&paste boilerplate code.

18ecca6331 utils: speed up pad linking utility functions by not trying pads that will never work
In gst_element_get_compatible_pad(), when trying to find a compatible pad on an
element for a given pad, there's no point in checking the element's sink pads
if the pad to link is a sink pad as well, or the element's source pads if the
given pad is a source pad already, since those would never be able to link
anyway. Should speed up linking using the convenience functions a little bit,
or at least reduce debug log output.

f547482e7c info: take the timestamp a tick later
The logging is not an atomic operation and because of the multi-threading we end
up with out-of-order log lines. Tools that present the log-file should probably
resort the lines. This change just takes the timestamp a bit closer to the
actual logging.

returned empty caps or if the intersection of all the caps on the other side

4cecd73c93 info: flush again after every line of debug output
g_printerr() used to do this for us. Also use libc's fprintf() functions,
to make sure the stderr pointer we use is actually compatible with the
libc linked against by GStreamer (which apparently may not always be the
same as what GLib is linked against on windows), and we don't need the
functionality ensured by g_fprintf().

Fixes #625295.

042e056776 binaryregistry: save and load release date time in GstPluginDesc

8c72758ec2 plugin: add release datetime field to GstPluginDesc and set it if GST_PACKAGE_RELEASE_DATETIME is defined
This is a string describing a date and/or date/time in a simple subset of
the ISO-8601 format, namely either "YYYY-MM-DD" or "YYYY-MM-DDTHH:MMZ" (with
'T' the date/time separator and the 'Z' indicating UTC).

The main purpose of this field is to keep track of plugin and element versions
on an absolute timeline, so it's possible to determine which one is newer when
comparing two date time numbers. This will allow us to express 'replaces'-type
relationships betweeen plugins and element factories in future, even across
different modules and plugin merges or splits (source module version numbers
aren't particularly useful here, since they can only meaningfully be compared
within the same module). It also allows applications and libraries to reliably
check that a plugin is recent enough without making assumptions about modules
or module versions.

We use a string here to keep things simple and clear, esp. on the build system
side of things.

9d4caf8d8c info: write debugging output to file if GST_DEBUG_FILE environment variable is set
This changes behaviour slightly in that we no longer output things
via g_printerr(), so any non-standard glib printerr handlers are no
longer called when GST_DEBUG is enabled. However, this seems not
really desirable in most cases anyway, and the GLib docs also say
that libraries should not use g_printerr() for logging.

Other stderr output (e.g. warnings, or application messages) will
of course not be captured in the log file this way.

GST_DEBUG_FILE=- will redirect debug output to stdout.

7fa58dbebd GstPad: Do not call gst_pad_accept_caps() when caps change
Instead just check that the caps intersect with the pad template.
The elements should properly accept/refuse the caps in setcaps().

Shaves off calling the default implementation of acceptcaps which does
an expensive gst_pad_get_caps() (so if you have 50 of those elements in
a row, you'd be doing factorial(50) gst_pad_get_caps...).

Does not break any module unit test and most apps work fine.

9c6b87510e pluginloading: add support for whitelisting based on plugin or source module name and path
This feature is primarily intended for use in plugin modules' unit tests.

Consider the following situation: gst-plugins-good is built against an
installed GStreamer core. An older version of gst-plugins-good is also
installed in that prefix, along with random other plugin modules. Now,
when doing 'make check' in the just-built gst-plugins-good tree, we
want to only load plugins from GStreamer core, gst-plugins-base, and
gst-plugins-good, but not random other modules (we don't want any unit
tests to fail just because some module in gst-plugins-bad has a broken
plugin_init, for example). Also, we want to only load gst-plugins-good
modules from the locally-built source tree, but not any of the older
gst-plugins-good modules installed. This is usually assured by loading
the ones in the source tree first (by adding that path first to the
right environment variables), but it gets tricky when plugins are
moved, removed, merged, or renamed, or the plugin filename changes.

Note that 'make check' should really work right without doing
'make install' or uninstalling the old gst-plugins-good package (or
any other gst-plugins-foo package) first.

Enter GST_PLUGIN_LOADING_WHITELIST. This environment variable may
contain source-package@path-prefix pairs separated by the platform
search path separator (G_SEARCHPATH_SEPARATOR_S). The source package
and path prefix are separated by the '@' character. The path prefix is
entirely optional, as is the '@' separator if no path is given.

It is also possible to filter based on plugin names instead of the name
of the source-package by specifying one or more plugin names separated
by commas before the optional path prefix.

In short, the following match patterns are possible:

   plugin1,plugin2@pathprefix or
   plugin1,plugin2@* or just
   plugin1,plugin2 or
   source-package@pathprefix or
   source-package@* or just
   source-package

So for our gst-plugins-good unit test example above, we  would set the
environment variable on *nix to something like this (will likely be a
relative path in practice):
gstreamer:gst-plugins-base:gst-plugins-good@/path/to/src/gst-plugins-good
