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.

Make it possible to add API specific flags to the ALLOCATION query. This makes

supported.

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.

7eae198be2 basetransform: refine metadata filter and transform
Add a vmethod to filter metadata that should be passed upstream. By default,
don't pass anything.
Add a vmethod to transform metadata from the input buffer to the output buffer.
By default, nothing is transformed or copied.

bdcf1dc3cd basetransform: remove metadata tagged with the memory tag
Remove metadata that describes the particular memory of the buffer it is
attached to. We need to do this because in non-passthrough mode we will allocate
new memory for our output buffer.

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.

beea57dca7 basetransform: fix reconfigure methods
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.

f3ca3f89f7 basetransform: improve propose_allocation
Always call the propose_allocation method and provide a default implementation
that passes the query on in passthrough mode so that subclasses can also call
this. Also pass if the transform is in passthrough mode so that the
implementation can adjust its algorithm.

not need to modify the caps.

b56bef1418 basetransform: Always call ::propose_allocation vfunc
And only forward the allocation query if we're working in
passthrough mode if no ::propose_allocation is implemented.
In place buffer transformations will change the buffer
content and require explicit handling of all metas.

d924c30f5b base: rename allocation vmethods
Name the allocation vmethod on srcpad decide_allocation because source pads will
have to decide what allocation parameters will be used.
Name the allocation vmethod on sinkpads propose_allocation because they will
need to configure the allocation query with a proposed values for upstream.

e4ee356449 basetrans: remove useless variables from prepare_output_buffer
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.

bdbc069348 Rework GstSegment handling
Improve GstSegment, rename some fields. The idea is to have the GstSegment
structure represent the timing structure of the buffers as they are generated by
the source or demuxer element.
gst_segment_set_seek() -> gst_segment_do_seek()
Rename the NEWSEGMENT event to SEGMENT.
Make parsing of the SEGMENT event into a GstSegment structure.
Pass a GstSegment structure when making a new SEGMENT event. This allows us to
pass the timing info directly to the next element. No accumulation is needed in
the receiving element, all the info is inside the element.
Remove gst_segment_set_newsegment(): This function as used to accumulate
segments received from upstream, which is now not needed anymore because the
segment event contains the complete timing information.
