Multiple files in the Raspberry Pi pipeline handler and IPA module are
missing SPDX headers. Add them with the following licenses:
- For code and documentation, use the BSD-2-Clause license, as for the
rest of the Raspberry Pi code.
- For the example pipeline handler configuration files, use the CC0-1.0
license to facilitate their usage.

This commit removes the Raspberry Pi CTT from the libcamera source tree.
This change is introduced to help a number of RPi users who are not so
faimilar with git and cloing the libcamera tree to run the CTT. The
library is also modularised in python for our users to incorporate into
their own "tuning" applications if needed. Licensing for our CTT tool
remains the same.
The Raspberry Pi CTT now lives at the following repo:
https://github.com/raspberrypi/ctt
and a package is avilable on pypi to install:
https://pypi.org/project/rpi-ctt/
This commit also removes the delayedctrls_parse.py script that has long
since code rotted.

The default noise/sharpness/gamma values are updated to reflect the
latest camera tuning work.
- Denoise is increased when not using temporal denoise.
- Denoise is reduced when benefitting from temporal denoise.
- Over-sharpening is reduced.
- High contrast gamma is slightly reduced.

The problem occurs when the calculation could lead to a final row (or
column) of grid squares with no pixels in them (and hence, NaNs).
One specific case is a Pi 5 with an image width (or height) of 1364,
so that's 682 Bayer quads. To give 32 grid squares it was calculating
22 quads per cell. However, 31 * 22 = 682 leaving nothing in the final
column.
The fix is to do a rounding-down division by the number of cells minus
one, rather than a rounding-up division by the number of cells. This
turns the corner case from one where the final row/column has no
pixels to one where we don't quite cover the full image, which is how
we have to handle these cases.

A max_gain parameter is added to the config file which we pass to the
lens shading calibration. This clamps the maximum luminance gain that
gets written into the tuning files so as to prevent overflows.
It is particularly useful for lenses that cut off the light completely
from the sensor corners, and allows usable tables to be generated for
them.

Source files in libcamera start by a comment block header, which
includes the file name and a one-line description of the file contents.
While the latter is useful to get a quick overview of the file contents
at a glance, the former is mostly a source of inconvenience. The name in
the comments can easily get out of sync with the file name when files
are renamed, and copy & paste during development have often lead to
incorrect names being used to start with.
Readers of the source code are expected to know which file they're
looking it. Drop the file name from the header comment block.
The change was generated with the following script:
----------------------------------------
dirs="include/libcamera src test utils"
declare -rA patterns=(
['c']=' \* '
['cpp']=' \* '
['h']=' \* '
['py']='# '
['sh']='# '
)
for ext in ${!patterns[@]} ; do
files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done)
pattern=${patterns[${ext}]}
for file in $files ; do
name=$(basename ${file})
sed -i "s/^\(${pattern}\)${name} - /\1/" "$file"
done
done
----------------------------------------
This misses several files that are out of sync with the comment block
header. Those will be addressed separately and manually.

Previously the code would brighten up images in case the Macbeth Chart
is slightly dark, and also zoom in on sections of it to look for
charts occupying less of the field of view. But it would not do both
together.
This change makes the search for smaller charts also repeat that
search for the brightened up images that it made earlier, thereby
increasing the chances of success for non-optimal tuning images.
There are also a couple of very small drive-by typo fixes.

The DNG specification is based on the TIFF file format and recommends
storing the raw image data in a SubIFD and the Exif tags in an Exif IFD.
Other options are allowed, even if not recommended, such as storing both
the raw image data and the Exif data in IFD0, as done by the TIFF/EP
specification.
libcamera-apps use pyexiv2 to produce DNG files, following the DNG
recommendation, while applications based on picamera2 use PiDNG, which
adopts the TIFF/EP structure. Why it does so is not currently clear (see
https://github.com/schoolpost/PiDNG/issues/65 for discussions on this
topic), but as files based on the DNG and TIFF/EP variants exist in the
wild, both need to be supported by ctt.
Add code to identify which tags are being used, and then load the
metadata from the correct tags.
