Headers which must not be exposed as part of the public libcamera API
should include base/private.h.
Any interface which includes the private.h header will only be able to
build if the libcamera_private dependency is used (or the
libcamera_base_private dependency directly).
Build targets which are intended to use the private API's will use the
libcamera_private to handle the automatic definition of the inclusion
guard.

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.

The libcamera-base.so will feature internal support functionality
that is utilised by libcamera, and can be shared in other places.
This new library provides a layer beneath libcamera which provides
common abstractions to internal objects.
A pkg-config file is generated and named libcamera-base.pc which allows
components such as external IPA modules to link directly to this library
if they need. Normal applications will reference this library through
the Requires: statement provided by the libcamera.pc package
configuration, and linkage will be handled automatically through the
pkg-config mechanisms.
No code is moved to this library yet, this patch only introduces the
framework, construction and linkage.

The libcamera library is moved to the first positional argument of the
pkg-config generator to automatically populate the name and filebase
values for the package.
As part of this, the shared library name is adjusted to the full library
name 'libcamera', without relying upon the automatic 'lib' prefix which
better represents the component and naming of the library.
As a result of this, the pkgconfig file is now named 'libcamera.pc' as
opposed to 'camera.pc', and applications desiring to reference libcamera
will need to search for 'libcamera' as a dependency rather than
'camera'.
The library itself is still created and installed as 'libcamera.so'.
An example meson.build file would need to be adjusted as the following:
- dependency('camera', required : true),
+ dependency('libcamera', required : true),

The ChromeOS specific Android HAL support was overly-complex to support
linking an additional library, and then passing the built object into
the libcamera.so build.
Now that it has its own distinct libcamera-hal.so, simplify the CrOS
integration to build directly into that library.
The removal of the -Wno-shadow here is intentional, as it is not
required for compilation of the camera3_hal.o object.

Commit 922833f774f6 ("libcamera: simple: Report sensor timestamp")
unconditionally tries to access the request through the capture buffer
to store the capture timestamp in the metadata. This causes a null
pointer dereference when using a converter, as the capture buffers are
free-wheeling in that case, and not associated with a request.
Fix this by getting the request from the user-facing buffer, which can
be the capture buffer when no converter is used.

The LogCategory instances are constructed on first use as static
variables in accessor functions, following the Meyers singleton pattern.
As a result, their destruction order is not guaranteed. This can cause
issues as the global Logger object, constructed in a similar fashion, is
accessed from the LogCategory destructor and may be destroyed first.
To fix this, keep the same singleton pattern, but allocate the
LogCategory instances dynamically. As they get registered with the
global Logger instance, we can destroy them in the Logger destructor.
This only avoids destruction order issues between LogCategory and
Logger, and doesn't address yet the fact that LOG() calls from
destructors of global objects may access an already destroyed Logger.

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.

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.

Capture requests are queued by the PipelineHandler base class to each
pipeline handler implementation using the virtual queueRequestDevice()
function.
However, if the pipeline handler fails to queue the request to the
hardware, the request gets silently deleted from the list of queued
ones, without notifying application of the error.
Reporting to applications that a Request has failed to queue by
cancelling and then completing it allows applications to maintain their

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.
