For consistency with UniqueFD, rename the fd() function to get().
Renaming UniqueFD::get() to fd() would have been another option, but was
rejected to keep as close as possible to the std::shared_ptr<> and
std::unique_ptr<> APIs.

The plane length is the length of the plane size. The buffer length
to be allocated for a plane is the offset and the length of
FrameBuffer::Plane.

This deadlock occurs when a buffer is holding the last reference on
the allocator. In gst_libcamera_allocator_release() we must drop the
object lock before dropping the last ref of that object since the
destructor will lock it again causing deadlock.
This was notice while switching camera or resolution in Cheese software.

Currently, when allocating buffers, the streams of the Camera object are
used. Instead the streams of the CameraConfiguration object should be
used. This is because the Camera object holds all available streams
while the CameraConfiguration holds only the streams associated with the
current configuration.

The Camera class currently requires the allocator to have no allocated
buffer before the camera is reconfigured, and the allocator to be
destroyed before the camera is released. There's no basis for these
restrictions anymore, remove them.
