We don't need to link to gthread-2.0 any longer, since all
the normal thread-related stuff is in GLib proper, and we
don't use g_thread_init() any more.

The function init_pre() in gstreamer/gst/gst.c calls setlocale(LC_ALL, ""),
which sets the locale to the values specified in the environment. This is
wrong for two reasons:
1. It is absolutely not the task of a library to decide on the correct locale
for a program. Some programs change the locale for various (good or bad)
reasons, and libraries should respect that. Programs where GStreamer's
overwriting of the locale causes bugs include Emacs [1, 2], Sublime Text [3],
and Lua [4].

Note that setting the locale can cause problems for programs that are not even
linked against GStreamer. In the case of Emacs, for example, GStreamer seems
to be initialized through GTK via libcanberra.
2. Setting the locale is not thread-safe, and therefore should not be done in a
library.

It's usually not a problem if a query fails if there's no peer,
especially as it will happen during pad linking (caps query)
quite often and spams the logs.
If we try to push sticky events but a probe dropped them, we don't mark
the event as received and mark the pad as PENDING_EVENTS. This ensures
that we resend the event the next time. For this we need to let the
custom flow return from the probe trickle up to
gst_pad_push_event_unchecked() so that we can differentiate between
OK and DROPPED probe returns.
First check that we can actually register the implementation before
making a GstMetaInfo. If we can't register we would otherwise end
up with an undefined type and an invalid GstMetaInfo.
It's possible that type registration fails because another metadata
with the same implementation name was already registered.
Fixes negotiation taking a ridiculous amount of
time (multiple 10s of seconds on a core2) when
there are duplicate entries in lists.
Could have a negative performance impact on other
scenarios because we now have to iterate the
dest list to avoid duplicates, but we don't
have a lot of lists any more these days, and
they tend to be small anyway. The negatives
are hopefully countered by the positive effects
of reducing the list length early on in the
process. And in any case, it's the right thing
to do.

This happened when glib was not using system printf, and caused the
internal gstreamer printf extensions to be used for all %p printfs,
causing crashes.
