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.
Based on patch by Andre Moreira Magalhaes.

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.

Also add test to make sure that if a pad probe is removed while it's
callback is running, the cleanup_hook isn't called again if it
returns GST_PAD_PROBE_REMOVE
Facilitate GstBuffer -> GstSample transition for some tags,
could be hard to catch otherwise when creating tags, since
it'll only be apparent later when someone tries to read the
tags.
We usually first create the stream_id for the stream_start event and then add
the pad to the element. This means that this functions should work when there
are no pads on the element yet.
Recheck for sticky events after doing a pad block because the pad block could
have caused a relink and then we need to resend the events to the newly linked
pad.
Fixes things like switching of visualisations.
The duration should be re-queried via a query using the
normal path, we don't want applications to use the value
from the message itself, since it might no match what a
duration query done from the sink upstream might yield.
Also disables duration caching in GstBin. It should be
added back again at some point.
When making a copy of the memory allocated from the default memory allocator,
make sure the new copy has the same alignment as the original memory.

Elements such as the GstIirEqualizerNBands would so far not store the properties
of their children. Now we also grab the properties of child elements and try to
restore them.
Not so useful: just adds/reads stuff from an internal GList without
actually doing anything with those paths, so remove for now:
gst_registry_add_path
gst_registry_get_path_list

No longer accept any old GObjects. This makes things nicer for
bindings. If a utility function that handles both nicely
is deemed worthwhile, we can still add one to gstutils.
