The current implementation of constructDefaultRequestSettings()
returns the same capture template for all the capture intent.
As the correctness of the generated template is verified by CTS it
is better to return an error for unsupported capture use cases.

The result metadata reports an arbitrary {30, 30} FPS range for the
AE algorithm.
The actual FPS range should be returned in the Request::metadata, but
as libcamera currently does not support that feature temporarily work
around the issue and return the FPS range requested by the camera
framework.

The request template returned by requestTemplatePreview() uses an
arbitrary {15, 30} Auto-Exposure algorithm FPS range. Use the one
calculated at static metadata creation time, which is consistent with
the camera limits.
Once template generation will be performed inspecting the requested
capture intent, the FPS range over which the AE algorithm can range
shall be tuned accordingly.

When configuring streams, the camera HAL is supposed to update the
gralloc usage flags to reflect the operations it will need to do on the
stream buffers. Failure to do so leads to incorrect format selection by
gralloc for the HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED format, as
gralloc will not take into consideration the need of the camera to
access the buffers.

The destination buffer for the post-processing component is
currently first mapped in the CameraDevice class and then passed
to CameraStream which simply calls the post-processor interface.

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

The Android camera2 API defines a RAW capture capability ([1]) for
devices that support "outputting RAW buffers and metadata for
interpreting them". This capability requires the camera device to
support RAW_SENSOR ([2]) as an output format. Despite what its name may
sound like, the RAW_SENSOR format is defined as a 16 bits RAW format,
not an opaque implementation-dependent format (which is instead called
RAW_PRIVATE). Devices may additionally support the RAW10 and RAW12
formats, but that isn't enough to claim RAW capture capability.
To comply with the API requirements, only report the
ANDROID_REQUEST_AVAILABLE_CAPABILITIES_RAW capability when 16-bit RAW is
supported.

The Android camera device HAL3 specification does not require a
camera to go through any explicit close() call between configurations.
It is legitimate for a camera to be configured, a number of requests
processed and then re-configured again without any explicit stop.
The libcamera Android camera HAL starts the Camera at the first handled
request, and only stops it at camera close time. This means that two
camera configuration attempts in the same streaming session are only
interleaved by capture requests handling.
The libcamera::Camera state machine requires the Camera to be stopped
before any configuration take place, and this currently doesn't happen.
Fix this by stopping the camera and the associated worker thread if
a configuration attempt is performed while the Camera is in running
state.
