This ensures that the lock of the internal pad is held while referencing
it's peer (= the target pad), which ensures that the peer is not
going to be unlinked/destroyed in the meantime.

This reverts commit 8162a583a4.
Automatically copying the sticky events makes it impossible for apps
and elements to filter the events with event probes. This causes
regressions (See #719437). The best option is to let the app/element
copy and filter the events themselves after the ghostpad target is
set.
Update the sticky events on SRC ghostpads when retargeting. This ensures
that the ghostpad has the exect same sticky events as the target pad. We
don't want to do this for SINK ghostpads, they got the events from
downstream and we don't want to overwrite them with the target pad
events.

Add the pad mode to the activate function so that we can reuse the same function
for all activation modes. This makes the core logic smaller and allows for some
elements to make their activation code easier. It would allow us to add more
scheduling modes later without having to add more activate functions.
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.
The fixate caps function was not used externally and we have vmethods in the
base classes where it is needed.
Update some docs.
simplify some fixate functions in the base classes. Also pass the untruncated
caps to the vmethod.
The internal proxy pad target is simply a cache of the internal proxy pad
peer. This patch uses the well implement GstPad peer handling to obtain the
target. This fixes issues with target not being set in both direction when
two ghostpads are linked together (empty bin).

This reverts commit cf4fbc005c.
This change did not improve the situation for bindings because
queries are usually created, then directly passed to a function
and not stored elsewhere, and the writability problem with
miniobjects usually happens with buffers or caps instead.
