The ipc_unixsocket.h and process.h internal headers don't need to
include event_notifier.h, the former because a forward declaration
suffices, and the latter because it doesn't use event notifiers. Remove
the unnecessary include, and include signal.h instead which is required
and was included indirectly through event_notifier.h.

In most cases the last reference to a Camera instance will be the one
held by the CameraManager. That reference gets released when the
CameraManager thread cleans up, just before it stops. There's no need to
delete the camera with deleteLater() in that case.
To optimize this case, use deleteLater() only when the camera gets
deleted from a different thread, and delete is synchronously otherwise.

The std::localtime() function isn't thread-safe, and we have no
guarantee whether other threads in the camera service may or may not
call it. Replace it with localtime_r(). This requires switching from
ctime to time.h, as there is no std::localtime_r() function.

When calculating the pipeline configuration for the IPU3 platform,
libcamera tries to be smart and select the smallest sensor frame
resolution large enough to accommodate the stream sizes
requested by the application.
While this makes a lot of sense, in practice optimizing the
selected sensor resolution makes the pipeline configuration calculation
process fail in multiple occasions, or results in stalls during capture.
As a trivial example, capturing with cam with the following command
line results in a stall:
$ cam -swidth=1280,height=720 -swidth=640,height=480 -c1 -C
Likewise, the Android HAL supported format enumeration fails in
reporting smaller resolutions as supported when used with the OV5670
sensor.
320x240:
DEBUG IPU3 ipu3.cpp:192 CIO2 configuration: 648x486-SGRBG10_IPU3
ERROR IPU3 imgu.cpp:408 Failed to calculate pipe configuration
ERROR IPU3 ipu3.cpp:299 Failed to calculate pipe configuration: unsupported resolutions.
640x480:
DEBUG IPU3 ipu3.cpp:192 CIO2 configuration: 320x240-SGRBG10_IPU3
ERROR IPU3 imgu.cpp:408 Failed to calculate pipe configuration
ERROR IPU3 ipu3.cpp:299 Failed to calculate pipe configuration: unsupported resolutions.
Furthermore the reference xml files used for the IPU3 camera
configuration on the ChromeOS platform restricts the number of sensor
resolution to be used for the OV5670 sensor to 2 from the 6 supported by
the driver [1].
The selection criteria of the correct CIO2 mode are not specified, and
for the time being, as a workaround, always use the sensor maximum
resolution at the expense of frame rate and bus bandwidth to allow the
pipeline to successfully support smaller modes for the OV5670 sensor and
solve pipeline stalls when capturing with both sensors.

Make the CameraStream encoder a private unique pointer and require its
initialization at construction time. This ties the encoder lifetime to
the CameraStream it has been created with, allowing to remove the
CameraStream destructor.
This change dis-allow creating a CameraStream and set the Encoder later,
which shall not happen now that we create CameraStream once we have all
the required information in place.

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.

The resolutions supported for the RAW formats cannot be tested from
a list of known sizes like the processed ones. This is mainly due to the
fact RAW streams are produced by capturing frames at the CSI-2 receiver
output and their size corresponds to the sensor's native sizes.
In order to obtain the RAW frame size generate a temporary
CameraConfiguration for the Role::StillCaptureRAW role and inspect the
map of StreamFormats returned by the pipeline handler.

When producing the list of image resolutions to claim as supported by the
camera HAL, the JPEG stream was assumed to be 'always valid' as, at the
time, there was no JPEG support in place at all.
With the introduction of support for JPEG compression, reporting
non-valid sizes as supported obviously causes troubles.
In order to avoid reporting non-supported resolutions as supported,
produce the list of available JPEG sizes by using the ones supported
by the YCbCr_420_888 format, from which the JPEG stream is encoded.

According to the Android camera HAL C interface documentation, the
camera service is supposed to set callbacks after initializing the HAL
and calling get_number_of_cameras(), before any other calls to the
module. We rely on this behaviour and use callbacks unconditionally,
which would lead to a crash if the camera service behaved incorrectly.
While the camera service isn't supposed to behave incorrectly,
gracefully handling the error when opening cameras isn't costly, and
provides better diagnostic than a crash.

Add a public member function to get the libcamera::Camera pointer
associated with the CameraDevice. This will help to find the CameraDevice
object in CameraHalManager when the hotplug support is extended in the
Android layer.

CameraDevice needs to be wrapper into the std::shared_ptr instead
of std::unique_ptr to enable refcounting. The refcounting will help
us to support hotplug and hot-unplug CameraHalManager operations
in the subsequent commit.
