Don't keep the registry locked whilst iterating over the plugins
or features with a filter function. This would deadlock if the
callback tried to access the registry from the function. Instead,
make a copy of the feature/plugin list and then filter it without
holding the registry lock. This is still considerably faster than
the alternative which would be to use a GstIterator.

This takes readings in the form of ...
<local_1> <remote_1> <remote_2> <local_2>
... with one observation per line, and then replays it using the
netclientclock code.
The output is the statistics structure emitted by the netclientclock,
which can then be analysed and tuned once we get those readings for
potential edge-cases.
It should be possible to find some inputs with "bad" data and convert
this into a unit test for future tweaks to run against.
By default, gst_parse_launch_full() creates a GstPipeline if there's more
than one toplevel element. Add a flag to let it use a GstBin instead.
Also fix the parser to let it use this flag for GST_TYPE_ELEMENT property
values, to avoid having GstPipelines inside other GstPipelines.

When going from READY to NULL all element pads are deactivated. If
simultaneously the pad is being removed from the element with
gst_element_remove_pad() and the pad is unparented, there is a race
where the deactivation will assert (g_critical) if the parent is lost at
the wrong time.
The proposed fix will check parent only once and retain it to avoid the
race.

This is the best guess we can make if such a buffer reached the collect
pad. This is uncommon, we do expect parsers to have tried and fixed that
if possible (or needed).

POSIX standards requires strsignal() to return a pointer to a char,
not a const pointer to a char. [1] On uClibc, and possibly other
libc's, that do not HAVE_DECL_STRSIGNAL, libcompat.h declares
const char *strsignal (int sig) which causes a type error.

First load all system presets, then all from the environment variable, then
from the app directory, then from the user directory. Any one in the chain
with the highest version completely replaces all previous ones, later ones
with lower versions are merged in without replacing existing presets.
This is basically the same behaviour as before, just that GST_PRESET_PATH is
inserted as another source of directories between the system and app presets.
It was added in ca08af1f17, but was
accidentially overriding the user preset path there. Which caused inconsistent
behaviour as new presets were still stored in the system path, just not loaded
from there. Meaning you could store a new preset (in the user path), just for
GstPreset to not find it anymore later (because it only looked in the
GST_PRESET_PATH instead of the user path).

Ensure that not-linked pads will drain out at EOS by
correctly detecting the EOS condition based on the EOS
pad flag (which indicates we actually pushed an EOS),
and make sure that not-linked pads are woken when doing
EOS processing on linked pads.

If an application calls gst_pad_query_caps from its "have-type" signal handler,
then the query fails because typefind->caps has not been set yet.
This patch sets typefind->caps in the object method handler, before the signal
handlers are called.

Many parsers are storing tags only in pre_push_frame(), if we wouldn't check
afterwards we would push buffers before those tags and a lot of code assumes that
tags are available before preroll.

This reverts commit 0835c3d656.
It causes deadlocks in decodebin, which currently would deadlock if the caps
are already on the pad in have-type and are forwarded while copying the sticky
events (while holding the decodebin lock)... as that might cause the next
element to expose pads, which then calls back into decodebin and takes the
decodebin lock.
This needs some more thoughts.
The alias define GST_TYPE_PARENT_BUFFER_META_API_TYPE is wrong and
breaks the usage of gst_buffer_get_parent_buffer_meta().
This patch fixes the GType alias and make another alias to keep the API
compatibility guarded by GST_DISABLE_DEPRECATED.
Also added a unit test.

gst_structure_new_empty() is not returning NULL in any valid scenarios,
checking for NULL here is useless. Especially because we would dereference any
NULL right after the NULL check again.
CID 1352037.
We previously check if the string ends on .class, as such strrchr() should
return something non-NULL. Add an assertion for that.
CID 1349642.
Pretty much every single element does
gst_element_class_add_pad_template (element_class,
gst_static_pad_template_get (&some_templ));
which is both confusing and unnecessary. We might just
as well add a function to do that in one step.
