b63ed9e066 ghostpad: return TRUE if target pad was already set
The state is as it should be, so no reason to return
FALSE really, everything's good.

e515aa06fe ghostpad: fix race-condition while tearing down
An upstream query will take a ref on the internal proxypad, and can
hence end up owning the last reference to that pad, causing a crash.

2e4c82d850 gst: Handle floating references consistently
If a function takes a floating reference parameter, it should also be
sinked in error cases. Otherwise the function behaves differently
between error and normal cases, which is impossible for bindings to
handle.

ab55ad7eaa ghostpad: Do nothing in _internal_activate_push_default
When calling gst_pad_activate_mode() on a ghostpad
gst_ghost_pad_activate_push_default() will be called. This will call
gst_pad_activate_mode() on the proxypad (which is internal of the
ghostpad), calling gst_ghost_pad_internal_activate_push_default(), which
again will call gst_pad_activate_mode() on the original ghostpad.

By simply returning TRUE in
gst_ghost_pad_internal_activate_push_default() the redundant call to
gst_pad_activate_mode() (for the same pad) is avoided.

a5001312cd ghostpad: Allow deactivation with no peer.
Allow deactivation in pull-mode, since that implies we
had a peer, activated in pull mode, then the peer disa-peer-ed ;)

154eefecc9 Don't compare booleans for equality to TRUE and FALSE
TRUE is 1, but every other non-zero value is also considered true. Comparing
for equality with TRUE would only consider 1 but not the others.

Also normalize booleans in a few places.

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.

6eb6d9ec38 docs: remove outdated and pointless 'Last reviewed' lines from docs
They are very confusing for people, and more often than not
also just not very accurate. Seeing 'last reviewed: 2005' in
your docs is not very confidence-inspiring. Let's just remove
those comments.

5973f8c2ca ghostpad: use gst_pad_get_peer to acquire a reference to the target pad
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.

fe36be1c03 Revert "ghostpad: copy sticky events to SRC ghostpads"
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.

8162a583a4 ghostpad: copy sticky events to SRC ghostpads
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.

2f1ed65339 pad: Merge pad mode activation functions
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.

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.

391568efde ghostpad: Don't cache internal proxy pad target
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).
