In the case the source has no caps, caps must be sent before segment. This
fixes few unit tests that where failing due to the new misordering warning.

Basetransform should not try to negotiate in passthrough mode but
respect the order of what we return in the transform_caps method.
A typical case is that you specify some specific new caps in the
caps property but also allow the current caps to pass.
Rename _do_simplify() to _simplify(). The name was introduced as a replacement
method for a deprecated method but we can now rename it again.
Fix some docs.
Make gst_caps_do_simplify() take ownership of the input caps and produce a
simplified output caps. This removes the requirement of having writable input
caps and the method can make the caps writable only when needed.
Rename gst_base_transform_suggest to gst_base_transform_reconfigure_sink because
that is what it does. Also remove the caps and size because that is not needed.
Rename gst_base_transform_reconfigure to gst_base_transform_reconfigure_src.
Remove some old unused code in capsfilter.
_set_caps only gets called when the buffer is actually pushed, so there
is a reasonably big window between when the initial caps are retrieved
and when the caps are set on our src pad. So we can't assume the not
having negotiated caps on our src pad means _get_caps still has to be
called.
Instead simply always suggest the new caps on buffer_alloc.
Remove the requirement to have to return a ref to the input buffer when in
passthrough mode. This saves a few ref/unref cycles and fixes another 0.11
FIXME.
Remove the caps and size from the prepare_output_buffer function. with
bufferpools and capsnego done differently, we don't need this in most cases and
if we do, we can simply use the transform_size function and get the caps from
the srcpad.
This reverts commit 9ef1346b1f.
Way to much for one commit and I'm not sure we want to get rid of the pad caps
just like that. It's nice to have the buffer and its type in onw nice bundle
without having to drag the complete context with it.
Implement a custom acceptcaps function. We can simply check if there is an
intersection with the new caps. This makes the accept caps function much faster.
See #621190
When we have an input buffer with caps and when those caps are different from
the caps we want, only then make a writable copy of the input buffer as the
output buffer and set the caps on that output buffer. This avoids some cases
where we took a subbuffer for setting caps that were the same.

Fix assertion in basetransform when the subclass chooses not to
allocate a buffer in prepare_buffer(), and make capsfilter error out
cleanly if requested to apply caps that don't completely specify the
buffer. Fixes#551509
