Make sure we take ownership of the buffer early without increasing its refcount
when we go in the collect function. This reduces the amount of copies needed in
order to make the buffer writable in most cases.
In some cases we can avoid allocating a subbuffer and instead simply ref
the buffer. Callers should perform _make_metadata_writable() in all
cases now.
Add a method to install a clipping function that is called when a buffer is
received. Users of collectpads can then perform clipping on the incomming
buffers.
Also retab the header file a little.
See #590265
This avoids:
* triple-checking for the GType when type-checking is enabled (see #597260)
* Avoids going through an expensive no-argument checking which landed in
glib-2.22
* Avoids going through 2 extrac functions (g_object_new -> g_object_new_valist)
There's not much point in using GST_DEBUG_FUNCPTR with GObject
virtual functions such as get_property, set_propery, finalize and
dispose, since they'll never be used by anyone anyway. Saves a
few bytes and possibly a tenth of a polar bear.
Without this, we risked:
* Checking the flushing state on an unexisting list
* Not setting the flushing state on pads that had just been added

Use the name of the pads instead of a pointer, helps in debugging.

Don't put the previously added destroy notify in the GstCollectData
struct as all it's padding is already used and we don't want to break
ABI. Instead put in the pad's GObject data for now. This should be
cleaned up for 0.11 (#402393).
