18a7a1d062 gst: Add better support for static plugins
API: GST_PLUGIN_STATIC_DECLARE()
API: GST_PLUGIN_STATIC_REGISTER()

Based on a patch by Håvard Graff <havard.graff@tandberg.com>.

This now allows GST_PLUGIN_DEFINE() to create a static plugin if
GST_PLUGIN_BUILD_STATIC is defined. The resulting plugin can be
statically linked or dynamically linked during compilation but
can't be dynamically loaded during runtime.

Also adds GST_PLUGIN_STATIC_DECLARE() and GST_PLUGIN_STATIC_REGISTER(),
which allows to register a static linked plugin easily.
It is still required to manually register every single statically linked
plugin from inside the application as this can't be automated in a portable
way.

A new configure parameter --enable-static-plugins was added that allows
to build all plugins we build here as static plugins.

Fixes bug #667305.

f43b756f39 plugin: fix name expansion for GST_PLUGIN_DEFINE macro
Make GST_PLUGIN_DEFINE use G_STRINGIFY() to convert the name argument
into a meaningful string. The advantage of this is that `name' can be
expanded from other macros defined in the plug-in element.

4889fd6b6f plugin: remove gst_plugin_name_filter
It's only used internally, most other users will likely
want to use gst_registry_find_plugin() directly instead
(and if not, they can easily walk the list and doing the
strcmp themselves).

19d4c0ba73 plugin: make GstPlugin object structure opaque for now
There's no reason anyone would want to derive from this, so
just make opaque until we manage to make all the private bits
private properly (which I'm not doing right now because it's
more invasive and I have registry modifications locally which
touch all that code as well).

This is an implementation detail really, and it's not

far as I'm aware, so just remove it for now.

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.

a9d1a493a7 Fixes for -Wwrite-strings
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.

f1850d1fee gst/gstplugin.h: Remove deprecation guards around GST_PLUGIN_DEFINE_STATIC.
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.

Also, in _gst_plugin_register_static(), make sure to call

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.
