d5b81aba6a basetrans: add an option to prefer passthrough
Basetransform attempts to do passthrough mode regardless of the order of
the transform_caps method. Add a method to disable this.
This is needed for elements like capsfilter that want to transform caps
based on the order of the caps property.

fee7080dff basetransform: getters for pool and allocator
Sometimes a transform filter would need the buffer pool or the memory
allocator negotiated by the base class, for example, for querying different
parameters, such as a bigger number of buffers to allocate by the buffer pool.

This patch expose a two getters accessors: one for the buffer pool and the
other for the memory allocator.

82eb275ef9 query: copy structure in _add_allocation_meta()
Make gst_query_add_allocation_meta() take a copy of the passed caps instead of
taking ownership. This makes it easier for the caller in most cases because it
doesn't have to make a copy and deal with NULL values.

105fa1ffde basetransform/basesrc: Do bufferpool configuration inside the default decide_allocation() implementation
This allows subclasses to override it, as is necessary for e.g. the
video-crop meta. It is now necessary that after decide_allocation()
there is always a allocator and a configured buffer pool inside the
query.

a3d5db491c trans: add transform_ip_on_passthrough
Add an option to control if transform_ip is called in passthrough mode or not.
for elements that don't want to look at the data in passthrough mode, this can
avoid some extra processing, mostly in subclasses.

41e9ca9b17 basetransform: remove automatic and undocumented setting of always_in_place
... which controls how to (forcibly) deal with (non-)writable data and
is not necessarily related to identical caps.

In particular, it is also not so helpful anymore with a more advanced
GstVideoFilter subclass which always has a transform_ip method currently,
even though its subclass may not have a corresponding _ip method.

db1318ab4a pad: change the semantics of get/pull_range a little
Make it so that one can specify a buffer for get/pull_range where the downstream
element should write into. When passing NULL, upstream should allocate a buffer,
like in 0.10.
We also need to change the probes a little because before the pull probe, there
could already be a buffer passed. This then allows us to use the same PROBE
macro for before and after pulling.
While we're at the probes, make the query probe more powerful by handling the
GST_PAD_PROBE_DROP return value. Returning _DROP from a query probe will now
return TRUE upstream and will not forward the probe to the peer or handler.
Also handle _DROP for get/pull_range properly by not dispatching to the
peer/handler or by generating EOS when the probe returns DROP and no buffer.
Make filesrc handle the non-NULL buffer passed in the get_range function and
skip the allocation in that case, writing directly into the downstream provided
buffer.
Update tests because now we need to make sure to not pass a random value in the
buffer pointer to get/pull_range

85c9543841 memory: group allocation parameters in a struct
Group the extra allocation parameters in a GstAllocationParams structure to make
it easier to deal with them and so that we can extend them later if needed.

functionality.
Add boxed type for GstAllocationParams.

edd2ffe4d4 memory: Add 0 padding
Change gst_allocator_alloc() so that we can also spicify flags and padding.
Add 2 new flags to mark the memory 0 prefixed/padded. This allows us to
remove some resizes in the base classes.
When allocating memory, memset prefix and padding with 0 when the flags tell
us to.
On resize, clear the zero padding flags if we can't guarantee the memory is
still 0 filled.
Update tests.

43abf99a8a caps: avoid using in-place oprations
Rework some caps operations so they don't rely on writable caps but instead take
ownership of the input caps and do _make_writable() only when needed.
Remove some const from caps functions, it does not make much sense for
refcounted objects and does not allow us to return a refcount to the const input
caps.
Rework the base classes fixate vmethods to not operate on the caps in-place.
All this saves us around 30% of caps and structure copy and new operations.

d6a28a6e3a basetransform: improve propose_allocation
Improve the propose allocation vmethod by passing the downstream allocation
query to it. This way the vmethod implementation can use properties of the
downstream allocation to generate the upstream query result. If there is no
downstream quety, it means that the element is working in passthrough mode.
Implement a default decide_allocation.

d6dfb07692 basetransform: improve prepare_output_buffer
Clean up the prepare_output_buffer function.
Reuse the input buffer when it is writable and when doing an
in-place but non-passthrough transform.

function. If subclasses implement a custom prepare_output_buffer, they must also
copy the metadata themselves.
Remove a useless memory copy because prepare_output_buffer already did that.

Add refcounting to the GstAllocator object.
