53cbbcd8d9 element: Fix doc and default implementation of send_event
The documentation states that gst_element_send_event is to "send an event
to an element".

Therefore we *send* upstream events to a source pad and downstream events
to a sink pad

78577fd8e4 element: Figure default send_event direction handling
If we get a downstream event we want to send it to a random SINK pad
(and vice-versa).

82e01491a0 element: Clarify docs about gst_element_get_request_pad() and remove deprecation part
This function is not really pad or slow for the common case of requesting a
pad with the name of the template. It is only slower if you to name your pads
directly instead of letting the element handle it.

Also there's no reason to deprecate it in favor of a more complicated function
for the common case.

2759882379 introspection: add missing (nullable) annotations to return values
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.

1911554cff element: set pads need-parent flag to false when removing
When a pad is added the need-parent flag is set to true, so when
they are removed the flag should be set back to false

This was preventing GstPads to be reused in elements (removed and
later re-added). A unit tests was added to verify that this is
working now.

The use case is tsdemux that has a program-number property and
allows the user to switch programs. In order to do that tsdemux
will remove the pads of the current program and add from the new
ones. The removed pads are kept in the demuxer for later if the
user selects the old program again.

b5c3e254b1 pad: remove getcaps and use caps query
Remove the getcaps function on the pad and use the CAPS query for
the same effect.
Add PROXY_CAPS to the pad flags. This instructs the default caps event and query
handlers to pass on the CAPS related queries and events. This simplifies a lot
of elements that passtrough caps negotiation.
Make two utility functions to proxy caps queries and aggregate the result. Needs
to use the pad forward function instead later.
Make the _query_peer_ utility functions use the gst_pad_peer_query() function to
make sure the probes are emited properly.

Move the flag to indicate that a new_base_time should be distributed to the
pipeline, from the async_start to the async_done message. This would allow us to
decide when to reset the pipeline time based on other reasons than the

The main goal eventually is to make the FLUSH events not reset time at all but
reset the time based on the first buffer or segment that prerolls the pipeline
again.

aad57970de element: Inherit element metadata and pad templates from parent classes
This allows to add pad templates and set metadata in class_init instead of
base_init. base_init is a concept that is not supported by almost all
languages and copying the templates/metadata for subclasses is the more
intuitive way of doing things.

Subclasses can override pad templates of parent classes by adding a new
template with the same now.

Also gst_element_class_add_pad_template() now takes ownership of the
pad template, which was assumed by all code before anyway.

Fixes bug #491501.

38c07bac1d element: When requesting an existing pad print a g_critical() instead of using an assertion
Some applications are requesting the same pad name multiple times
and the behaviour is undefined and different from element to element
but we don't want to break applications that work just fine.

In 0.11 this check should be an assertion again, although elements
have to do manual checking if the pad already exists again because
it can't be done in a threadsafe way here.
