When a request is given to a pipeline handler, it must parse the request
and identify what actions the pipeline handler should take to enact on hardware.
In the case of the VIVID pipeline handler, we identify the buffer from the only
supported stream, and queue it to the video capture device.

We can now add buffer management, and connect up our bufferReady signal
to a callback.
Note that we provide the ability to export buffers from our capture
device (data->video_) using the exportBuffers() functionality from the
V4L2VideoDevice which allows a FrameBufferAllocater to obtain buffers
from this device.
When buffers are obtained through the exportFrameBuffers API, they are
orphaned and left unassociated with the device, and must be reimported
at start() time anyway. This allows the same interface to be used
whether internal buffers, or external buffers are used for the stream.
When a buffer completes, we call the buffer completion handler on the
pipeline handler, and because we have only a single stream, we can also
immediately complete the request.

When the configurations have been generated and validated, they can be
applied to a device.
Vivid supports only a single stream, so it directly obtains the first
StreamConfiguration from the CameraConfiguration.
The VIVID catpure device is a V4L2Video device, so we generate a
V4L2DeviceFormat to apply directly to the capture device node.
Note that we convert the libcamera Format stored in
cfg.pixelFormat to a V4L2PixelFormat using V4L2PixelFormat helper. This
currently defaults to the single-planar formats, and should be extended
to support the Multiplanar configuration from the V4L2Device.
[todo Repair the link between the multiplanar configuration of the
V4L2VideoDevice and the pixel format selection]
Following the call to set the format using the Kernel API, if the format
has been adjusted in any way by the kernel driver, then we have failed
to correctly handle the validation stages, and thus the configure
operation is idendified has having failed.
Finally stream specific data can be directly stored and set as
reflecting the state of the stream.
[NOTE: the cfg.setStream() call here associates the stream to the
StreamConfiguration however that should quite likely be done as part of
the validation process. TBD]

Implement the support for Generating and Validating the streams the
Camera can provide.
Vivid is a simple case with only a single stream.
Test the configurations can be generated and reported with cam -I:

The PipelineHandlerFactoryBase class has a name that is propagated to
the PipelineHandler instance it creates.
In present implementation, this name comes from the
REGISTER_PIPELINE_HANDLER registration macro. It corresponds to the
stringified name of the PipelineHandler derived class. Therefore,
PipelineHandler factories and instances names can be quite long such as
"PipelineHandlerRkISP1".
A libcamera user may have to explicitly refer to a PipelineHandler name
for configuration purpose: one usage of the name can be to define a
pipeline handlers match list and their priorities. It is desired, for
user convenience, to use a short name to designate a pipeline handler.
Reusing the short pipeline names already defined in the meson option
files is an existing and consistent way of naming pipelines.
This change adds an explicit name parameter to the
REGISTER_PIPELINE_HANDLER registration macro. That parameter is used to
define the name of a pipeline handler factory, instead of the current
pipeline handler class name.
Each pipeline registration is updated accordingly. The short name
assigned corresponds to the pipeline directory name in the source tree.
It is consistent with pipelines names used in meson.
Changing the pipeline name has an impact on the IPA modules: each module
defines a IPAModuleInfo structure. This structure has a pipelineName
member defining the pipeline handler name it shall match with.
Therefore, each internal IPA module definition has to be changed to have
its IPAModuleInfo pipelineName name updated with the short pipeline
handler name.
In addition to this pipelineName member, the IPAModuleInfo structure
also has a name member, associated to the IPA module name. Having
renamed the pipelines to a short name, the pipeline name and the IPA
module names of the IPAModuleInfo structure are the same: for in-tree
IPA, they correspond to the respective pipeline and IPA subdirectories
in the source tree. However the IPA name could be different, for
instance with a close source IPA implementation built out-of-tree. Thus,
it makes sense to keep the IPA name in that structure, as the 2
definitions may not always be redundant.

Some V4L2 formats translate to the same pixel format, e.g. YU12 and
YM12 both produce YUV420. In this case our ISP driver advertises the
same size range for both, but we must not record the same thing twice
for the same pixel format (which will cause a failure later on).
Instead, ignore the V4l2 format if the pixel format has already been
seen.

Add a parameter to the histogram constructor that takes a transformation
function to apply to all the bins upon construction.
This is necessary notably for the rkisp1, as the values reported from
the hardware are 20 bits where the upper 16-bits are meaningful integer
values and the lower 4 bits are fractional and meant to be discarded. As
adding a right-shift parameter is probably too specialized, a generic
function is added as a parameter instead.
While at it, optimize the existing constructor to avoid push_back() into
a vector with a known final size.

second call is guaranteed to be a nop.

Black may not be represented as 0 pixel value for given hardware, it may
be higher. If this is not compensated then various problems may occur
such as low contrast or suboptimal exposure.
The black pixel value can be either retrieved from a tuning file for the
given hardware, or automatically on the fly. The former is the right
and correct method, while the latter can be used when a tuning file is
not available for the given hardware. Since there is currently no
support for tuning files in software ISP, the automatic, hardware
independent way, is always used. Support for tuning files should be
added in future but it will require more work than this patch.
The patch looks at the image histogram and assumes that black starts
when pixel values start occurring on the left. A certain amount of the
darkest pixels is ignored; it doesn't matter whether they represent
various kinds of noise or are real, they are better to omit in any case
to make the image looking better. It also doesn't matter whether the
darkest pixels occur around the supposed black level or are spread
between 0 and the black level, the difference is not important.
An arbitrary threshold of 2% darkest pixels is applied; there is no
magic about that value.
The patch assumes that the black values for different colors are the
same and doesn't attempt any other non-primitive enhancements. It
cannot completely replace tuning files and simplicity, while providing
visible benefit, is its goal. Anything more sophisticated is left for
future patches.
A possible cheap enhancement, if needed, could be setting exposure +
gain to minimum values temporarily, before setting the black level. In
theory, the black level should be fixed but it may not be reached in all
images. For this reason, the patch updates black level only if the
observed value is lower than the current one; it should be never
increased.
The purpose of the patch is to compensate for hardware properties.
General image contrast enhancements are out of scope of this patch.
Stats are still gathered as an uncorrected histogram, to avoid any
confusion and to represent the raw image data. Exposure must be
determined after the black level correction -- it has no influence on
the sub-black area and must be correct after applying the black level
correction. The granularity of the histogram is increased from 16 to 64
to provide a better precision (there is no theory behind either of those
numbers).

To enable the Simple Soft ISP and Soft IPA for simple pipeline handler
configure the build with:
-Dpipelines=simple -Dipas=simple
Also using the Soft ISP for the particular hardware platform must
be enabled in the supportedDevices[] table. It is currently enabled
for and only for qcom-camss.
If the pipeline uses Converter, Soft ISP and Soft IPA aren't
available.

The converterBuffers_ and the converterQueue_ are not that specific
to the Converter, and could be used by another entity doing the format
conversion.

conversionBuffers_, conversionQueue_ and useConversion_ to
disassociate them from the Converter.

Define the Soft IPA main and event interfaces, add the Soft IPA
implementation.
The current src/ipa/meson.build assumes the IPA name to match the
pipeline name. For this reason "-Dipas=simple" is used for the
Soft IPA module.
Auto exposure/gain and AWB implementation by Dennis, Toon and Martti.
Auto exposure/gain targets a Mean Sample Value of 2.5 following
the MSV calculation algorithm from:
https://www.araa.asn.au/acra/acra2007/papers/paper84final.pdf
Use CameraSensorHelper to convert the analogue gain code read from the
camera sensor into real analogue gain value. In the future this makes
it possible to use faster AE/AGC algorithm. Right now the CameraSensorHelper
lets us use the full range of analogue gain values.
If there is no CameraSensorHelper for the camera sensor in use, a
warning log message is printed.

Add a CPU based SwStats implementation for SoftwareISP / SoftIPA use.
This implementation offers a configure function + functions to gather
statistics on a line by line basis. This allows CPU based software
debayering to call into interleave debayering and statistics gathering
on a line by line basis while the input data is still hot in the cache.
This implementation also allows specifying a window over which to gather
statistics instead of processing the whole frame.

SharedMemObject class
The SharedMemObject class template contains a fair amount of inline code
that does not depend on the template types T. To avoid duplicating it in
every template specialization, split that code to a separate base
SharedMem class.
We don't define copy semantics for the classes (we don't need one at the
moment) and we make them non-copyable since the default copy constructor
would lead to use-after-unmap.
