When appending/prepending tags, avoid re-creating (and copying) lists if we already
have one and instead just append/prepend the GValue to the list.

Before this patch gst_init would intercept --help, causing for example
cheese's --help to look like this:
[hans@shalem cheese]$ cheese --help
Usage:
cheese [OPTION...] - GStreamer initialization
Help Options:
-h, --help Show help options
--help-all Show all help options
--help-gst Show GStreamer Options
gst_init is the only gfoo_init function which does this.

API: gst_value_array_append_and_take_value
API: gst_value_list_append_and_take_value
We were already using this internally, this makes it public for code
which frequently appends values which are expensive to copy (like
structures, arrays, caps, ...).
Avoids copies of the values for users. The passed GValue will also
be 0-memset'ed for re-use.
New users can replace this kind of code:
gst_value_*_append_value(mycontainer, &myvalue);
g_value_unset(&myvalue);
by:
gst_value_*_append_and_take_value(mycontainer, &myvalue);

But do this only for events that are not dropped by flushing,
i.e. do it only for everything except SEGMENT and EOS.
Without this we might drop a CAPS event if flushing happens
at an unfortunate time and nobody is resending the CAPS event.
https://bugzilla.gnome.org/show_bug.cgi?id=700806
If a pad block was triggered from sending a sticky event downstream, it
could happen that the pad block is relinking pads, which then requires
to resend previous sticky events.
Previous patch was inforcing a complete ordering of the sticky events, while
in fact, only STREAM_START, CAPS and SEGMENT events need proper ordering.
See: https://bugzilla.gnome.org/show_bug.cgi?id=688188
We can prevent buggy element from causing other elements to fail or crash
by sorting sticky event at insertion. In this case, we also warn as this
is not supposed to happen.

Fixes abort when the old specifiers are used. Fix up the conversion
specifier, it would get overwritten with 'c' below to the extension
format char, which then later is unhandled, leading to the abort.
Also fix up and enable unit test for this.

Source elements with limited bandwidth capabilities and supporting
buffering for downstream elements should set this flag when answering
a scheduling query. This is useful for the on-disk buffering scenario
of uridecodebin to avoid checking the URI protocol against a list of
hardcoded protocols.
Bug 693484
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.
The gst_plugin_feature_rank_compare_func() should return
negative value, if the rank of both PluginFeatures are equal and
the name of first PluginFeature comes before the second one.

Don't use snprintf(), but use sprintf instead and do our own
length calculations, because glibc may complain about us passing
%n in a format string if the string is in writable memory, and
here the format string is always in writable memory since we
construct it on the fly. This happens if glibc has been compiled
with _FORTIFY_SOURCE=2, which seems to be the case on some
distros/systems). On the upside, we now use the sprintf code path
on all systems which should be better from a maintenance point
of view.

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.

Don't use just GLIB_HAVE_ALLOCA_H to check if alloca is available,
that's just for the header. GLib may define alloca for us otherwise
too irrespective of GLIB_HAVE_ALLOCA_H.
Fixes compiler warning with mingw32:
gst/printf/vasnprintf.c:73:0: warning: "alloca" redefined
Does not do anything yet. On a sidenote, we can't just use
%p\001 or so to signal the extension because g-i complains
about an invalid ascii character then, so have to resort to
something more elaborate, such as %p\aA etc.

and remove all the printf extension/specifier stuff for
the system printf. Next we need to add back the custom
specifiers to our own printf implementation.
https://bugzilla.gnome.org/show_bug.cgi?id=613081
We will add support for our own printf modifiers, so we can
get nice debug log output on all operating systems irrespective
of the specific libc version used.
