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.

Original commit message from CVS:
* gst/gstplugin.c: (_gst_plugin_initialize):
Fix old-style static plugins via GST_PLUGIN_DEFINE_STATIC
again, which I broke two commits ago when changing the API
of gst_plugin_register_static(): the g_list_foreach() in
_gst_plugin_register_static still assumed the old function
signature and would therefore fail (re-fixes #510187).
* gst/gstplugin.c: (_num_static_plugins), (_static_plugins),
(_gst_plugin_register_static), (gst_plugin_register_static):
Revert the (technically correct) change to call g_thread_init() from
the pre-main() constructor. This will break programs which call
g_thread_init() without an if (!g_thread_supported()) guard in their
main function. We could just blame it on GLib or the application, but
it's probably best to just avoid this altogether and simply not use
any GLib functions here and use plain old malloc() with a simple
array to store the plugins to register later when gst_init() is
finally called (re-fixes #510187).
* tests/check/gst/gstplugin.c: (GST_GNUC_CONSTRUCTOR_DEFINED),
(GST_GNUC_CONSTRUCTOR_DEFINED), (plugin_init_counter),
(plugin1_init), (plugin2_init), (plugin3_init), (GST_START_TEST),
(GST_START_TEST), (gst_plugin_suite):
Dumb unit test to make sure the old GST_PLUGIN_DEFINE_STATIC still
works.
Original commit message from CVS:
* gst/gst.c: (init_post):
* gst/gstplugin.c: (_gst_plugin_register_static),
(gst_plugin_register_static), (_gst_plugin_initialize):
* gst/gstplugin.h: (GstPluginFilter):
Change API of gst_plugin_register_static() to not take
a GstPluginDesc, but rather just take all the arguments
in a GstPluginDesc directly. This is more intuitive and
avoids certain mistakes when porting code from
GST_PLUGIN_DEFINE_STATIC to gst_plugin_register_static().
Fixes#510187.
* tests/check/gst/gstplugin.c:
Fix up for changed API.

* gst/gst.c: (init_post):
* gst/gstplugin.c: (_gst_plugin_register_static),
(gst_plugin_register_static), (_gst_plugin_initialize),
(gst_plugin_register_func):
* gst/gstplugin.h: (GST_PLUGIN_DEFINE_STATIC):
API: add gst_plugin_register_static() and deprecate
GST_PLUGIN_DEFINE_STATIC, since it's not portable
(#498924).
Also, in _gst_plugin_register_static(), make sure to call
g_thread_init() before calling GLib functions such as
g_list_append() if we're not initialised yet, since that
may lead to random crashes with older GSlice/GLib versions.
* tests/check/gst/gstplugin.c:
Adapt unit test to above changes.

* docs/gst/gstreamer-sections.txt:
Add new API to check plugin feature version requirements.
* check/gst/gstplugin.c: (test_version_checks), (gst_plugin_suite):
Some basic tests for the above.

* gst/gstplugin.c:

* gst/gstregistry.c:
Getting tired of debugging. Disabled all the unreffing of
plugins and features, which fixes the segfaults, but of
course leaks like crazy. At least playbin works.
