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.

See 8fe63000de for why having a TRUE/FALSE
return value is a bad idea.
I've scanned a few plugins and they generally get it wrong and aren't
unloadable when they return FALSE.
This changes some APIs in compatible ways:
- Some functions now take "const char *" arguments, not "char *"
- Some structs now have "conts char *" members, not "char *"
The changes may cause warnings when compiling with the right warning
flags. You've been warned.
Also adds -Wwrite-strings as a warning flag in configure.ac.

Original commit message from CVS:
* gst/gstplugin.h: (GST_PLUGIN_DEFINE_STATIC):
Remove deprecation guards around GST_PLUGIN_DEFINE_STATIC.
This makes gtk-doc complain, but results in slightly better
compiler errors. The old _gst_plugin_register_static() is
still guarded, so there'll be a compiler warning about that
instead. Fixes#510187 too.
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/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.

Original commit message from CVS:
* gst/gstplugin.h:
Cast description string constants in GST_PLUGIN_DEFINE macros
to a (gchar*) to make C++ code using these macros compile
without warning with g++-4.2 (see #462737). Even if slightly
ugly, this seems preferable to putting the description strings
into the GLib quark table or making the structure member a
const gchar * and doing casts in core code that allocs and
frees these strings, or requiring a cast in the C++ code.

* gst/gstplugin.h:

Put more strings into the GLib quark table. No need to keep
a hundred-something copies of identical version strings,
license strings, package name strings and package origin
strings around.

* gst/gststructure.h (struct _GstStructure): Only one pointer of
padding.
* gst/gstquery.h (struct _GstQuery): Only one pointer of padding.
* gst/gstpluginfeature.h: Remove a comment in PluginFeature.
* gst/gstplugin.h (struct _GstPluginClass): Add some padding.
* gst/gstobject.h: (struct _GstObject): Only one pointer of
padding; reduces object size by about 30%. We don't expect
anything else to go into gstobject.
* gst/gstminiobject.h (struct _GstMiniObject)
(struct _GstMiniObjectClass): Only one pointer of padding; the
payload is only a pointer and two ints anyway. For the class there
are only two methods as well.
* gst/gstelement.h (struct _GstElementClass): Removed
the state_changed signal callback, it is not used.

Registry rewrite. Changes registry from being a file created
by a tool into a simple cache file created automatically by
libgstreamer. Removed gst-register (because it's no longer
needed). Remove registry pools, because we only have one
registry implementation (XML). Fix up other subsystems as
necessary.
Original commit message from CVS:
add a source plugin description field, to represent the source
module this plugin is a part of. By default GST_PLUGIN_DEFINE
will set it to PACKAGE, which is automake's idea of the name of
the source project.

are important when linking not the template, which is more
general than the current caps.
