When a request completes, a debug message is generated to help
identify the request and the number of streams it contains.
The printed number of streams is however the number of output buffers
requested by the camera framework, not the number of streams generated
by libcamera. In facts, some output buffers are generated by
post-processing, and not directly from the camera.
As the debug message prints the libcamera identifier for the Request, it
is more logical to print the number of streams generated by the camera
instead of the total number of streams.

Mapped streams are generated by post-processing and always require a
source buffer to process image data from.
In case a Mapped stream is requested but its source stream is not, it
is required to allocate a buffer on the fly and add it to the
libcamera::Request.
Make sure a source stream is available for all mapped streams, and if
that's not the case, add a dedicated buffer to the request for that
purpose.

Introduce a dedicated worker class derived from libcamera::Thread.
The worker class maintains a queue for post-processing requests
and waits for a post-processing request to become available.
It will process them as per FIFO before de-queuing it from the
queue.
The entire post-processing handling iteration is locked under
streamsProcessMutex_ which helps us to queue all the post-processing
request at once, before any of the post-processing completion slot
(streamProcessingComplete()) is allowed to run for post-processing
requests completing in parallel. This helps us to manage both
synchronous and asynchronous errors encountered during the entire
post processing operation. Since a post-processing operation can
even complete after CameraDevice::requestComplete() has returned,
we need to check and complete the descriptor from
streamProcessingComplete() running in the PostProcessorWorker's
thread.
This patch also implements a flush() for the PostProcessorWorker
class which is responsible to purge post-processing requests
queued up while a camera is stopping/flushing. It is hooked with
CameraStream::flush(), which isn't used currently but will be
used when we handle flush/stop scenarios in greater detail
subsequently (in a different patchset).
The libcamera request completion handler CameraDevice::requestComplete()
assumes that the request that has just completed is at the front of the
queue. Now that the post-processor runs asynchronously, this isn't true
anymore, a request being post-processed will stay in the queue and a new
libcamera request may complete. Remove that assumption, and use the
request cookie to obtain the Camera3RequestDescriptor.

Notify that the post processing for a request has been completed,
via a signal. The signal is emitted with a context pointer along with
status of the buffer. The function CameraDevice::streamProcessingComplete()
will finally set the status on the request descriptor and complete the
descriptor if all the streams requiring post processing are completed.
If buffer status obtained is in error state, notify the status to the
framework and set the overall error status on the descriptor via
setBufferStatus().
We need to track the number of streams requiring post-processing
per Camera3RequestDescriptor (i.e. per capture request). Introduce
a std::map to track the post-processing of streams. The nodes
are dropped from the map when a particular stream post processing
is completed (or on error paths). A std::map is selected for tracking
post-processing requests, since we will move post-processing to be
asynchronous in subsequent commits. A vector or queue will not be
suitable as the sequential order of post-processing completion
of various requests won't be guaranteed then.
A streamsProcessMutex_ has been introduced here as well, which will be
applicable to guard access to descriptor's pendingStreamsToProcess_ when
post-processing is moved to be asynchronous in subsequent commits.

Currently, we use Camera3RequestDescriptor::Status to determine:
- When the descriptor has been completely processed by HAL
- Whether any errors were encountered, during its processing
Both of these are essential to know whether the descriptor is eligible
to call process_capture_results() through sendCaptureResults().
When a status(Success/Error) is set on the descriptor, it is ready to
be sent back via sendCaptureResults(). However, this might lead to
undesired results especially when sendCaptureResults() runs in a
different thread (for e.g. stream's post-processor async completion
slot).
This patch decouples the descriptor status (Success/Error) from the
descriptor's completion status (pending or complete). The advantage
of this is we can set the completion status when the descriptor has
been processed fully by the layer and we can set the error status on
the descriptor wherever an error is encountered, throughout the
lifetime of the descriptor in the HAL layer.
While at it, introduce a wrapper completeDescriptor() around
sendCaptureResults(). completeDescriptor() as the name suggests will
mark the descriptor as complete, so it is ready to be sent back.
The locking mechanism is moved from sendCaptureResults() to this wrapper
since the intention is to use completeDescriptor() in place of existing
sendCaptureResults() calls.
Also make sure the sequence of abortRequest() call happens in the same
order at all places i.e. after its added to the descriptors_ queue. Fix
one of the abortRequest() call accordingly.

The camera3_stream_buffer_t structure is meant to communicate between
the camera service and the HAL. They are short-live structures that
don't outlive the .process_capture_request() operation (when queuing
requests) or the .process_capture_result() callback.
We currently store copies of the camera3_stream_buffer_t passed to
.process_capture_request() in Camera3RequestDescriptor::StreamBuffer to
store the structure members that the HAL need, and reuse them when
calling the .process_capture_result() callback. This is conceptually not
right, as the camera3_stream_buffer_t pass to the callback are not the
same objects as the ones received in .process_capture_request().
Store individual fields of the camera3_stream_buffer_t in StreamBuffer
instead of copying the whole structure. This gives the HAL full control
of how data is stored, and properly decouples request queueing from
result reporting.

The Camera3RequestDescriptor structure stores, for each stream, the
camera3_stream_buffer_t and the libcamera FrameBuffer in two separate
vectors. This complicates buffer handling, as the code needs to keep
both vectors in sync. Create a new structure to group all data about
per-stream buffers to simplify this.
As a side effect, we need to create a local vector of
camera3_stream_buffer_t in CameraDevice::sendCaptureResults() as the
camera3_stream_buffer_t instances stored in the new structure in
Camera3RequestDescriptor are not contiguous anymore. This is a small
price to pay for easier handling of buffers, and will be refactored in
subsequent commits anyway.

There's no need to store it in the Camera3RequestDescriptor. Build it

This requires storing the result metadata created in

effect of this change is that the request metadata lifetime will match

Camera3RequestDescriptor is a utility structure that groups information
about a capture request. It can be and will be extended to preserve the
context of a capture overall. Since the context of a capture needs to
be shared among other classes (for e.g. CameraStream) having a private
definition of the struct in CameraDevice class doesn't help.
Hence, de-scope the structure so that it can be shared with other
components (through references or pointers). Splitting the structure to
a separate file will help avoiding circular dependencies when using it
through the HAL implementation.

When the camera HAL detects an out-of-order completion of a request, it
sends to the camera framework a CAMERA3_MSG_ERROR_DEVICE error.
Such error not only forces the service to close the camera as prescribed
by the camera3 specification, but in some implementation (specifically
the ChromeOS one) it causes the camera service to abort and exit.
This prevents any error messages from being printed by libcamera, as the
library gets terminated before getting to that point, and also hides the
printout of error messages that lead to out-of-order completion, making
it impossible to get from the output log what happened.
Move the call to notifyError() at the end of the error path and demote
the error message to LogLevels::Error from Fatal to let the service
implementation decide how to handle CAMERA3_MSG_ERROR_DEVICE errors.
Before this patch, when waiting on a fence fails and the capture
request is not queued to the Camera, we get an out-of-order completion
but no backtrace. With this patch applied the error path is visible:

Commit d165f7da34b8 ("android: camera_device: Configure one stream for
identical stream requests") introduced the ability to generate through
post-processing YUV streams of identical size and format.
However the change didn't fully take into account the situation
where only mapped streams are contained in the request submitted by
the camera service to the HAL. In this case the Request will be queued
with no buffers and refused by the Camera.
Even if this seems a corner case it causes a few CTS to fail, and more
problematically it triggers out-of-order completion of requests, causing
the camera service to abort.

The problem is happening because we seem to add a CameraStream
associated buffer (depending on the CameraStream::Type) to the Request,
in CameraDevice::processCaptureRequest().
However, when the camera stops, all the current buffers are marked with
FrameMetadata::FrameCancelled and proceed to completion. But the buffer
associated with the CameraStream (that was previously added to the
request) has now been cleared out with a part of streams_.clear(), even
before the camera stop() has been invoked. Any access to those request
buffers after they have been cleared, will result in a crash.

There is a possibility that an out-of-order completion of capture
request happens by calling process_capture_result() directly on error
paths. The framework expects that errors should be notified as soon as
possible, but the request completion order should remain intact.
An existing instance of this is abortRequest(), which sends the capture
results on flushing state, without considering order-of-completion.
Since we have a queue of Camera3RequestDescriptor tracking each
capture request placed by framework to libcamera HAL, we should be only
sending back capture results from a single location, by inspecting
the queue. As per the patch, this now happens in
CameraDevice::sendCaptureResults().
Each descriptor is now equipped with its own status to denote whether
the capture request is complete and ready to be send back to the
framework or needs to be waited upon. This ensures that the order of
completion is respected for the requests.
Since we are fixing out-of-order request completion in abortRequest(),
change the function to read from the Camera3RequestDescriptor directly,
instead of camera3_capture_request_t. The descriptor should have all the
information necessary to set the request buffers' state to error.

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.

Usage of 'method' to refer to member functions comes from Java. The C++
standard uses the term 'function' only. Replace 'method' with 'function'
or 'member function' through the whole code base and documentation.
While at it, fix two typos (s/backeng/backend/).
The BoundMethod and Object::invokeMethod() are left as-is here, and will
be addressed separately.

Currently, all UVC cameras are reported with CameraLocationExternal [1]
by libcamera-core since there is no universal information or standard,
to know the location of these cameras. However, in the libcamera HAL
layer, we can make an informed decision whether it's external or
internal, simply by checking its presence in the HAL configuration
file.
The CameraHalManager will now assign the numerical id of the camera
accordingly when initializing the CameraDevice, based on the camera
facing value set in the HAL config file.

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.

The config_ pointer is reset in all error paths of the
CameraDevice::configureStreams() function, except when
Camera::configure() fails. Fix it by using a local unique pointer to
store the configuration until the end of the function, to avoid similar
issues in the future.

Move the functionality for the following components to the new
base support library:
- BoundMethod
- EventDispatcher
- EventDispatcherPoll
- Log
- Message
- Object
- Signal
- Semaphore
- Thread
- Timer
While it would be preferable to see these split to move one component
per commit, these components are all interdependent upon each other,
which leaves us with one big change performing the move for all of them.
