The descriptors_ map holds Camera3RequestDescriptor(s) which are
per-capture requests placed by the framework to libcamera HAL.
CameraDevice::requestComplete() looks for the descriptor for which the
camera request has been completed and removes it from the map.
Since the requests are placed in form of FIFO and the framework expects
the order of completion to be FIFO as well, this calls for a need of
a queue rather than a std::map.
This patch still keeps the same lifetime of Camera3RequestDescriptor as
before i.e. in the requestComplete(). Previously, a descriptor was
extracted from the map and its lifetime was bound to requestComplete().
The lifetime is kept the same by manually calling .pop_front() on the
queue. In the subsequent commit, this is likely to change with a
centralized location of dropping descriptors from the queue for request
completion.

Returning a non-managed pointer can cause leaks. Use a unique_ptr<>
instead to avoid possible future issues.
The std::move() for the planes argument to the FrameBuffer constructor
is dropped as it's misleading. FrameBuffer has no constructor that takes
an rvalue reference to planes, so the vector was copied despite the
move. This only clarifies the intent, no functional change is
introduced.

CameraStream creates PostProcessor and FrameBufferAllocator in
the constructor. CameraStream assumes that a used post processor
is JPEG post processor. Since we need to support various post
processors, we would rather move the creation to configure() so
as to return an error code if no proper post processor is found.
This also moves FrameBufferAllocator and Mutex creation for
consistency.

The MappedFrameBuffer is a convenience feature which sits on top of the
FrameBuffer and facilitates mapping it to CPU accessible memory with
mmap.
This implementation is internal and currently sits in the same internal
files as the internal FrameBuffer, thus exposing those internals to
users of the MappedFramebuffer implementation.
Move the MappedFrameBuffer and MappedBuffer implementation to its own
implementation files, and fix the sources throughout to use that
accordingly.

Commit 7532caa2c77b ("android: camera_device: Reset config_ if
Camera::configure() fails") reworked the configuration sequence to
ensure that the CameraConfiguration pointers gets reset when
configuration fails. This inadvertently causes a null pointer
dereference, as the CameraStream constructor accesses the camera
configuration through CameraDevice::cameraConfiguration() before the
internal config_ pointer is set.
Fix this by passing the configuration pointer explicitly to the
CameraStream constructor.

Implement the flush() camera operation in the CameraDevice class
and make it available to the camera framework by implementing the
operation wrapper in camera_ops.cpp.
Introduce a new camera state State::Flushing to handle concurrent
flush() and process_capture_request() calls.
As flush() can race with processCaptureRequest() protect it
by introducing a new State::Flushing state that
processCaptureRequest() inspects before queuing the Request to the
Camera. If flush() is in progress while processCaptureRequest() is
called, return the current Request immediately in error state. If
flush() has completed and a new call to processCaptureRequest() is
made just after, start the camera again before queuing the request.

Currently only stop() and the first call to processCaptureRequest()
start and stop the camera, and they're not meant to race with each
other. With the introduction of flush() the camera can be stopped
concurrently to a processCaptureRequest() call, hence access to the

The CameraDevice class maintains the camera state in the 'running_'
boolean flag to check if the camera has to be started at the first
received process_capture_request() call which happens after the camera
had been stopped.
So far this was correct, as the operations that change the camera
could only start or stop the camera, so a simple boolean flag
was enough.
To prepare to handle the flush() operation that will introduce a new
'flushing' state, replace the simple plain boolean flag with an
enumeration of values that define the CameraState.

The current implementation of CameraDevice::requestComplete() which
handles event notification and calls the framework capture result
callback does not handle error notification precisely enough.
In detail:
- Error notification is an asynchronous callback that has to be notified
to the framework as soon as an error condition is detected, and it
independent from the process_capture_result() callback
- Error notification requires the HAL to report the precise error cause,
by specifying the correct CAMERA3_MSG_ERROR_* error code.
The current implementation only notifies errors of type
CAMERA3_MSG_ERROR_REQUEST at the end of the procedure, before the
callback invocation.
Rework the procedure to:
- Notify CAMERA3_MSG_ERROR_DEVICE and perform library tear-down in case
a Fatal error is detected
- Notify CAMERA3_MSG_ERROR_REQUEST if the libcamera::Request::status is
different than RequestCompleted and immediately call
process_capture_result() with all buffers in error state.
- Notify the shutter event as soon as possible
- Notify CAMERA3_MSG_ERROR_RESULT in case the metadata cannot be
generated correctly and call process_capture_result() with the right
buffer state regardless of metadata availability.
- Notify CAMERA3_MSG_ERROR_BUFFER for buffers whose post-processing
failed
While at it, return the CameraStream buffer by calling
cameraStream->putBuffer() regardless of the post-processing result.
No regression detected when running CTS in LIMITED mode.

The CameraDevice::streams_ vector of CameraStream instances is
currently mostly accessed by index. The current implementation
creates all the CameraStream during the first loop that inspects the
camera3_stream instances and then update the index of the
StreamConfiguration associated with the CameraStream during a second
loop that inspects MJPEG streams. A third loop creates the JPEG encoder
associated with camera streams that produce MJPEG format.
As the index-based association is hard to follow and rather fragile,
rework the creation and handling of CameraStream:
1) Make the StreamConfiguration index a constructor parameter and a
private struct member. This disallows the creation of CameraStream
without a StreamConfiguration index assigned.
2) Create CameraStream only after the associated StreamConfiguration
has been identified. The first loop creates CameraStream for non-JPEG
streams, the second for the JPEG ones after having identified the
associated StreamConfiguration. Since we have just created the
CameraStream, create the JPEG encoder at the same time instead of
deferring it.
This change removes all accesses by index to the CameraDevice::streams_
vector.
No functional changes intended, but this change aims to make the code
easier to follow and more robust.
