This type encodes BayerFormats in an explicit way, that makes them
easier to use than some of the other more opaque type formats. This
makes the BayerFormat useful for editing or manipulating Bayer types
more easily.

We implement 2D transforms as an enum class with 8 elements,
consisting of the usual 2D plane transformations (flips, rotations
etc.).
The transform is made up of 3 bits, indicating whether the transform
includes: a transpose, a horizontal flip (mirror) and a vertical flip.

We build libcamera with -Wno-unused-parameter and this doesn't cause
much issue internally. However, it prevents catching unused parameters
in inline functions defined in public headers. This can lead to
compilation warnings for applications compiled without
-Wno-unused-parameter.
To catch those issues, remove -Wno-unused-parameter and fix all the
related warnings with [[maybe_unused]].

Provide a MappedFrameBuffer helper class which will map

common interface and cleanup.
This allows MappedBuffer instances to be created from Camera3Buffer types.

A system's firmware description is recorded differently in sysfs
depending if the system uses DT or ACPI. Add a helper to abstract
this, allowing users not to care which of the two are used.
For DT-based systems, the path is the full name of the DT node that
represents the device. For ACPI-based systems, the path is the absolute
namespace path to the ACPI object that represents the device. In both
cases, the path is guaranteed to be unique and persistent as long as the
system firmware is not modified.

Object::deleteLater() ensures that the deletion of the Object
takes place in a thread it is bound to. Deleting the Object
in a different thread is a violation according to the libcamera
threading model.
On hot-unplug of a currently streaming camera, the last reference
of Camera when dropped from the application thread (for e.g. QCam's
thread), the destructor is then called from this thread. This is not
allowed by the libcamera threading model. Camera is meant to be deleted
in the thread it is bound to - in this case the CameraManager's thread.

This commit adds support to schedule the deletion of an Object to the
thread it is bound to (similar to [1]). An Object getting destroyed
by a different thread is considered as a violation as per the
libcamera threading model.
This will be useful for an Object where its ownership is shared via
shared pointers in different threads. If the thread which drops the
last reference of the Object is a different thread, the destructors
get called in that particular thread, not the one Object is bound to.
Hence, in order to resolve this kind of situation, the creation of
shared pointer can be accompanied by a custom deleter which in turns
use deleteLater() to ensure the Object is destroyed in its own thread.

frame action to send the sensor staggered write configuration to the

The new helpers return a reference to the size, to allow chaining the

size.alignDownTo(16, 16).alignUpTo(32, 32)
.boundTo({ 40, 80 }).expandTo({ 16, 80 });
