GCC5 does not provide prototypes for the math library functions defined
in the math.h header for the std:: namespace.
Include the C++ <cmath> header in place of <math.h> as it defines
overloads for the std::abs and std::fmod function.
This goes intentionally against the libcamera coding guidelines, and
is reported as warning by checkpatch.py.

Add a mapping from HAL RAW formats to the direct equivalent of libcamera
formats. With this change it is possible to capture RAW images as long
as the hardware can deliver frames in a format that is native to the
HAL.
More work is needed to deal with unpacked 8, 10 and 12 RAW formats as
they don't directly map to a native HAL format. Nor do they belong in
the RAW_OPAQUE category as the content format is generic and not
uncommonly supported by hardware.

Instrument the ImgU component to dynamically calculate the image
manipulation pipeline intermediate sizes.
To correctly configure the ImgU it is necessary to program the IF, BDS
and GDC sizes, which are currently fixed to the input frame size.
The procedure used to calculate the intermediate sizes has been ported
from the pipe_config.py python script, available at:
https://github.com/intel/intel-ipu3-pipecfg
at revision:
61e83f2f7606 ("Add more information into README")
Define two structures (ImgUDevice::Pipe and ImgUDevice::PipeConfig)
to allow the pipeline handler to supply and retrieve configuration
parameters from the ImgU.
Finally, add a new operation to the ImgUDevice that calculates
the pipe configuration parameters based on the requested input and
output sizes.

The IPU3CameraConfiguration::streams_ field was used to keep an
association between the StreamConfiguration and the assigned streams
before CameraConfiguration::setStream() was called at configure() time.
The stream assignment was based on the order in which elements were
inserted in the vector, implementing a fragile association between
streams and their intended configurations.
As it is now possible to assign streams at validation time, there is no
need to keep that association in place, and the streams_ vector is now
unused.
Remove it and the associated accessor method from the
IPU3CameraConfiguration class.

Remove the adjustStream() and assignStream() methods, and perform stream
adjustment and assignment while iterating the StreamConfiguration
items.
The adjustStream() implementation had some arbitrary assumption, like
the main output having to be as large as the sensor resolution, and did
not take into account the different alignment requirements between the
main output and the viewfinder output.
The assignStream() implementation also assumes only full-size streams
can be produced by the main output, and having it as a separate function
prevents adjusting streams according to which output they are assigned.
Blend the two implementation in a single loop and perform the required
stream adjustment and assignment in one go.
As streams are now assigned at validate() time, remove the same
operation from the configure() function.

The current implementation of the Camera::configure() method zeroes the
stream pointers assigned to the StreamConfiguration items before calling
the pipeline handler configure() operation, just after the
CameraConfiguration has been validated.
This discards the stream assignment performed at pipeline hander
validation time, requiring platforms that need to perform that early
assignment to maintain the association in place with custom data
structures.
To allow pipeline handlers to use StreamConfiguration::setStream() at
validate() time, zero the stream assignment before calling validate().

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.
