Provide the request SensorTimestamp as the buffer completion time. This
is fake, as there is no SensorTimestamp on the VIVID pipeline as it's a
virtual video device, but it provides a suitable data point.

When constructing the camera, we parse the available controls on the
video capture device, and map supported controls to libcamera controls,
and initialise the defaults.
The controls are handled during queueRequestDevice for each request and
applied to the device through the capture node.

The VIVID pipeline handler retains state globally of it's controls.
Ensure that when we configure this specific pipeline we set initial
parameters on the device that suit our (specific) needs.
This introduces how controls can be set directly on a device, however
under normal circumstances controls should usually be set from libcamera
controls as part of a request. These are VIVID specific only.

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]

releaseBuffers() unconditionally calls ioctl(REQBUFS, 0) to release device
buffer allocations through the close() and class destructor functions. If
another libcamera process is running concurrently with a different sensor, it
would cause the ioctl to fail in the kernel because the buffer queue is owned
owned by the other process. This in turn would cause libcamera to generate an
error log message.
Fix this by ensuring the releaseBuffers() only calls ioctl(REQBUFS, 0) if there
have been buffers previously allocated by the device. This is done by testing
the presense of the V4L2BufferCache in the object.

Meson introduces a .replace() method in version 0.58.0. However we aim
to restrict ourselves to 0.56 meson features, as released by Debian
stable.
The recent introduction of release management infrastructure makes use
of the .replace() method to fix up the version string when there is a
mis-match between the release version and any (lack) of tags in the git
version description. This breaks when built on systems with only meson
0.56.
Refactor this to use a concatenation of the project version and a
stripped git version to regenerate the full source version string that
will be reported by libcamera.

Android 11's toolchain does not support std::filesystem, but

This adds a very small difference in behaviour, as File::exist() will

Each declaration of a LogCategory will create a new LogCategory, and
will be stored in an unordered_set Logger::categories_. This means that
when a plugin .so is unloaded and loaded, as happens when destructing
and creating a CamereManager, we'll get duplicate categories.
The Logger::registerCategory docs say "Log categories must have unique
names. If a category with the same name already exists this function
performs no operation.". The code does not comply with this.
We solve the issue with two changes:
Change the unordered_set to a vector for simplicity, as there's no need
for an unordered_set.
Instead of using the LogCategory constructor to create new categories in
_LOG_CATEGORY() macro, use a factory method. The factory method will
return either an existing LogCategory if one exists with the given name,
or a newly created one.
