The video device is currently opened in the SimpleCameraData
constructor. This requires opening the video devices on-demand the first
time they're accessed, which gets in the way of refactoring of
per-entity data storage in the pipeline handler.
Move opening of the video device to the SimpleCameraData::init()
function. The on-demand open mechanism isn't touched yet, it will be
refactored later.

Record the sink and source pads through which an entity is traversed in
the list of entities stored in the camera data. This prepares for
implementing mutually exclusive access to entities between cameras.
The debug message that displays detected pipelines now prints pads to

The bufferLength_ member variabled is checked to have a positive value
before being used, to catch usage before the variable is set. The
variable is initialized to zero at construction time, which renders the

Do not compare higher precision of the ratios, as it might lead to
absurd selection of sensor size for a relatively low requested
resolution size.
For example:
The imx258 driver supports the following sensor resolutions:
- 4208x3118 = 1.349583066
- 2104x1560 = 1.348717949
- 1048x780 = 1.343589744
It can be inferred that, that the aspect ratio only differs by a small
mantissa with each other. It does not makes sense to select a 4208x3118
for a requested size of say 640x480 or 1280x720, which is what is
happening currently.
($) cam -c1 -swidth=640,height=480,role=raw
- CIO2 configuration: 4208x3118-SGRBG10_IPU3 [*]
In order to address this constraint, only compare the ratio with single
precision to make a better decision on the sensor resolution policy
selection.
($) cam -c1 -srole=raw,width=640,height=480
- CIO2 configuration: 1048x780-SGRBG10_IPU3 [*]

The current implementation of getSensorFormat() prioritizes sensor
sizes that match the output size FOV ratio.
Modify the frame size selection procedure to prioritize resolutions
with the same FOV as the sensor's native one, to avoid cropping in the
sensor pixel array.
For example:
- on a Soraka device equipped with ov13858 as back sensor, with a
native resolution of 4224x3136 (4:3), when requested to select the
sensor output size to produce 1080p (16:9) a frame size of 2112x1188
(16:9) is selected causing the ImgU configuration procedure to fail.
If a resolution with the same FOV as the sensor's native size, such
as 2112x1568 (4:3), is selected the pipeline works correctly.

This prepares a base to introduce custom selection of sensor format
based on platform(Soraka or Nautilus) constraints. The changes in
selection policy will be introduced in a subsequent patch.
The function is copied from CameraSensor::getFormat() in the IPU3
pipeline handler code to be later changed on top.
The copy is not verbatim and has a minor change as follows:
CameraSensor::getFormats() has access to a V4L2Subdevice::Formats
internally and use it directly to iterate over supported camera sensor
frame sizes. The copy is adapted to use the CameraSensor::sizes(mbusCode)
instead, to enumerate over the supported frame sizes as per
mbusCodesToPixelFormat map.
No functional changes in this patch.

In CameraSensor, the mbusCodes() and sizes() accessor functions
retrieves all the supported media bus codes and the supported sizes
respectively. However, this is quite limiting since the caller
probably isn't in a position to match which range of sizes are
supported for a particular mbusCode.
Hence, the caller is most likely interested to know about the sizes
supported for a particular media bus code. This patch transforms the
existing CameraSensor::sizes() to CameraSensor::sizes(mbuscode) to
achieve that goal.
The patch also transforms existing CIO2Device::sizes() in IPU3 pipeline
handler to CIO2Device::sizes(PixelFormat) on a similar principle. The
function is then plumbed to CameraSensor::sizes(mbusCode) to enumerate
the per-format sizes as required in
PipelineHandlerIPU3::generateConfiguration().

Pipeline managers sets a default value to StreamConfiguration::size. The
original fixation code was attempting to use it, but as it was truncating
the caps to its first structure it would never actually find a best match.
In this patch, instead of truncating, we weight various matches using the
product of the width and height delta. We also split delta from ranges
apart and prefer fixed size over them as ranges are not reliable.
This patch also removes the related todo, as it seems that libcamera core
won't go further then providing this default value and won't be sorting the
format and size lists.

This demonstrates the way to use process() call when the EventStatReady

when prepare() is called, the parameters are filled with the updated

IPCMessage::IPCMessage(uint32_t cmd)
IPCMessage::IPCMessage(const Header &header)

Regarding (de)serialization in isolated IPA calls, we have four layers:
- struct
- byte vector + fd vector
- IPCMessage
- IPC payload
The proxy handles the upper three layers (with help from the
IPADataSerializer), and passes an IPCMessage to the IPC mechanism
(implemented as an IPCPipe), which sends an IPC payload to its worker
counterpart.
When a FileDescriptor is involved, previously it was only a
FileDescriptor in the first layer; in the lower three it was an int. To
reduce the risk of potential fd leaks in the future, keep the
FileDescriptor as-is throughout the upper three layers. Only the IPC
mechanism will deal with ints, if it so wishes, when it does the actual
IPC. IPCPipeUnixSocket does deal with ints for sending fds, so the
conversion between IPCMessage and IPCUnixSocket::Payload converts
between FileDescriptor and int.
Additionally, change the data portion of the serialized form of
FileDescriptor to a 32-bit unsigned integer, for alightnment purposes
and in preparation for conversion to an index into the fd array.
Also update the deserializer of FrameBuffer::Plane accordingly.
