libcamera: Improve Request life cycle tracking
The current logging to track the status of a Request when running the Android camera HAL provide the following information: When a Request is queued to libcamera: HAL camera_device.cpp:1776 '\_SB_.PCI0.I2C2.CAM0': Queueing Request to libcamera with 1 HAL streams When a Request completes: Request request.cpp:268 Request has completed - cookie: 138508601719648 The queueing of a Request reports the number of streams it contains while the completion of a Request reports the address of the associated cookie. This makes very hard to keep track of what Requests have completed, as the logging associated with a queue/complete event does not allow to identify a Request easily. Add two more printouts to make it easier to track a Request life cycle. To make it possible to print the Request cookie in the CameraDevice class add a method to access it from the CameraRequest class. The result looks like the following trace: Request request.cpp:92 Created request - cookie: 140701719392768 HAL camera_device.cpp:1710 '\_SB_.PCI0.I2C2.CAM0': Queueing request 140701719392768 with 1 streams HAL camera_device.cpp:1747 '\_SB_.PCI0.I2C2.CAM0': 0 - (4160x3104)[0x00000023] -> (4160x3104)[NV12] (direct) ... Request request.cpp:268 Request has completed - cookie: 140701719392768 HAL camera_device.cpp:1800 '\_SB_.PCI0.I2C2.CAM0': Request 140701719392768 completed with 1 streams..
