Add coefficients sets in the YAML tuning file to allow using different set
depending of the image color temperature (provided by AWB algorithm).
During processing, LSC algorithm computes coefficients by doing a linear
interpolation between the two closer set.

Control the framerate by passing the controls::FrameDurationLimits
during Camera::start(). Framerate in gstreamer is expressed as
GST_TYPE_FRACTION so we maximise on maintaining it as a fraction
throughout and only do arithematic computations as and when required
(to compute frame-duration and vice-versa).
To weed out abritrary framerate as input, place the clamping via the
controls::FrameDurationLimits provided after camera::configure() phase.
This is handled by a helper function
gst_libcamera_clamp_and_set_frameduration().
Set the bound checked framerate (done in the above mentioned helper)
into the caps and pass the ControlList containing the frame-duration
to Camera::start(ctrls).

Configure the camera before exposing the caps valid controls values
(and bounds) are available. These control values might be of interest
to be exposed on the capabilites, which otherwise, would not be
available if the camera is configured after the update caps event.
For instance, the FrameDurationLimits are computed by RPi's IPA in
its configure(). Hence, we need to Camera::configure() to happen in
order to know the FrameDurationLimits, that can be exposed in the caps.
This ties into the framerate support for libcamerasrc which will happen
in a follow-up commit.

The PipelineHandler::generateConfiguration() function allocates a
CameraConfiguration instance and returns it. The ownership of the
instance is transferred to the caller. This is a perfect match for a
std::unique_ptr<>, which the Camera::generateConfiguration() function
already returns. Update PipelineHandler::generateConfiguration() to
match it. This fixes a memory leak in one of the error return paths in
the IPU3 pipeline handler.
While at it, update the Camera::generateConfiguration() function
documentation to drop the sentence that describes the ownership
transfer, as that is implied by usage of std::unique_ptr<>.

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.

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.

LogCategory just stores the char * that was given to it in the
constructor, i.e. it refers to memory "outside" LogCategory. If the
LogCategory is defined in a .so that is unloaded, then it leads to the
LogCategory pointing to freed memory, causing a crash.
Fix this by taking a copy of the name by using a std::string instead of
just storing the pointer.
