80ddde400a elementfactory: make sure gstreamer has been initialized when creating elements
Add gst_is_initialized() guard to gst_element_factory_make(), so
people who forgot to call gst_init() get a useful warning for what
seems to be a common enough mistake.

34abe02458 query: minor gst_query_add_buffering_range() code reflow

unnecessary g_value_unset(), move g_value_init()+set_int64_range()
closer to where they're needed.

7e5a9580ef structure: add gst_structure_{id_}take_value()
Add _set_value() variants that take ownership of the value passed
instead of making a copy of the value. This is useful for setting
values to things that aren't refcounted (e.g. GValueArrays or
strings or string arrays, etc.).

a9a82da134 bin: add message-forward option
Add an option to forward all the internal messages that would otherwise be
filtered such as EOS, SEGMENT and ASYNC messages.
This allows the application to, for example, detect that a partial pipeline is
prerolled or reached eos.
The original messages are wrapped inside an element message because the parent
bins are not supposed to see those internal messages escape.

60fba4df8b gstpad: Fix flush-stop event handling
A flush-stop event would make a pad unflushing, causing it
to start acting as an activated pad. This, for example,
could lead to the chain function being called when stuff
isn't initialized.

This could happend when setting qtdemux to NULL while a seek
was being handled in the upstream filesrc (in push mode).

This patch makes it check if it is activated before setting
it to unflushing.

d7f59ca0c4 pad: Deprecate GST_FLOW_IS_FATAL() and GST_FLOW_IS_SUCCESS()
The problem with both macros is, that they suggest something that isn't true.
If GST_FLOW_IS_FATAL is true, there could still be a problem for many elements
and they should stop what they're currently doing and return that value
upstream (e.g. not-linked in a parser). If GST_FLOW_IS_SUCCESS is false, it
could still be that this is "ok" for the element (e.g. not-linked for a demuxer
on a few of its pads but not all).

It's better to not have these "convenience" macros but instead let people
*think* about the handling of different flow returns, that makes sense for
their element. And we should document the expected handling of flow returns for
different classes of elements in the plugin writer's guide.

Fixes bug #628014.

57cc780c45 bin: relax the source element check
When there is a sink inside a bin, the SINK flag is set on the bin. When we are
trying to iterate the source elements, also include the bins with the SINK flag
because they could also contain source elements, in which case they are also a
source.

This solves the case where sending an EOS to a pipeline didn't get dispatched to
all source elements.

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.

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.

00697e8529 xml: keep dummy gst_xml_get_type() function for g-i even if rest of GstXML is removed
Add a minimal gst_xml_get_type() function, so that gobject-introspection doesn't
break the compilation if we're compiling with GST_REMOVE_DEPRECATED defined or
--disable-loadsave having been passed to configure. Until someone figures out
a better way at least.

this, to avoid frustration. See countless bug reports in bugzilla.

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

Fixes #619815 and #619717.
