Niklas Söderlund 6cd505ac89 libcamera: pipeline: Remove explicit buffer handling 
With the FrameBuffer interface in place there is no need for the Camera
to call into the specific pipelines allocation and freeing of buffers as
it no longer needs to be synchronized with buffer allocation by the
application.

Remove the function prototypes in the pipeline handler base class and
fold the functionality in the pipelines start() and stop() functions
where needed. A follow up patch will remove the now no-op
Camera::allocateBuffers() and Camera::freeBuffers().

**A complex camera support library for Linux, Android, and ChromeOS**

Cameras are complex devices that need heavy hardware image processing
operations. Control of the processing is based on advanced algorithms that must
run on a programmable processor. This has traditionally been implemented in a
dedicated MCU in the camera, but in embedded devices algorithms have been moved
to the main CPU to save cost. Blurring the boundary between camera devices and
Linux often left the user with no other option than a vendor-specific
closed-source solution.

To address this problem the Linux media community has very recently started
collaboration with the industry to develop a camera stack that will be
open-source-friendly while still protecting vendor core IP. libcamera was born
out of that collaboration and will offer modern camera support to Linux-based
systems, including traditional Linux distributions, ChromeOS and Android.
