When requesting a pad from a template and it's already linked, this
means it was a static pad. Since we only want to return an *available*
pad, we must return NULL ... but we must also remove the reference
we got from getting that static pad.
The "No need to unref" message (which wasn't true for quite some time)
dates back from the very very very first commit introducing the 0.10
features.
When using seek_simple() in combination with other kinds of seeks, this
becomes problematic. seek_simple() does not reset the stop position to
GST_CLOCK_TIME_NONE but keeps whatever a previous seek did. So for example
when doing a seek_simple() after a rate=-1 seek, we would usually get
assertions that start>stop (and stop being the old stop from the rate=1 seek).

We already had a _full() version, but having that alone seems inconsistent.
Add a non-full version that mirrors the behaviour of gst_pad_link() vs
gst_pad_link_full().
Checking the current element's state when we're adding pads to
the parent element is checking the wrong thing.
Silences a 'attempting to add an inactive pad to a running element'
warning when adding a ghost pad to a running parent bin of the parent
bin of the element.

This is a useful function to automatically add ghost pads when linking
two elements across bin boundaries without know their exact parentage.
e.g. when using gst_parse_bin_from_description (with or without it ghosting pads),
one can simply retreive the src/sink pads from the bin to link to another pad.
Similar functionality is provided by gst_element_link_pads{_full}() however only
by pad name rather than by actual pads.

Do not ignore the caps argument when requesting a pad by template.
This is particularly harmful when the pad caps query by default
returns ANY so it will match the first template instead of the
one that actually intersects with the caps.

gst_bin_sync_children_states() will iterate over all the elements of a bin and
sync their states with the state of the bin. This is useful when adding many
elements to a bin and would otherwise have to call
gst_element_sync_state_with_parent() on each and every one of them.

If an element implements wrongly the URI query and set the uri to NULL and if
the element calls gst_pad_create_stream_id at some point, it will lead to crash
as the uri is not supposed to be NULL in the gst_pad_create_stream_id_internal
function.

Previously gst_element_link_pads_full() forgot to unreference or release
request pads in several error cases. Also comments were added mentioning
why releasing is not necessary in some places.

Support for (nullable) was added to G-I at the same time as nullable
return values. Previous versions of G-I will not mark return values as
nullable, even when an (allow-none) annotation is present, so it is
not necessary to add (allow-none) annotations for compatibility with
older versions of G-I.

Boxed types can't be derived from, and we don't support

gstutils.c:3659:41: error: format string is not a string literal

This makes gst_parse_bin_from_description() return an element instead of
a bin if there's only one element. Also changed gstparse.c to use this,
so gst-launch won't create superfluous bins.

All streams that have the same group id are supposed to be played
together, i.e. all streams inside a container file should have the
same group id but different stream ids. The group id should change
each time the stream is started, resulting in different group ids
each time a file is played for example.
This reverts commit 1a1a9e143f.
This breaks the pipelines/tagschecking unit test for some reason
(fakesrc ! capsfilter ! qtmux linking fails now). It might be
a bug in the unit test of course, but someone will need to
investigate this. Reverting for now.

motivation comes from: /* FIXME: why not gst_pad_get_pad_template (pad); */
this code path is quite nicer, we now only revert to creating the template
if gst_pad_get_pad_template fails.
with this fork, we gain a non-allocation of GstCaps *templcaps
https://bugzilla.gnome.org/show_bug.cgi?id=692508
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.
In the proxy_query_caps function, also filter against the filter in the query.
We don't need to filter against the filter in the query anymore in the default
caps query function because we already did this in the proxy_query_caps.
