The CameraConfiguration::validateColorSpaces() function performs color
space validation on a camera configuration, by validating the color
space of each stream individually, and optionally ensuring that all
streams share the same color space. The individual validation is very
basic, limited to ensuring that raw formats use a raw color space.
Color spaces are more constrained than that:
- The Y'CbCr encoding and quantization range for RGB formats must be
YcbcrEncoding::None and Range::Full respectively.
- The Y'CbCr encoding for YUV formats must not be YcbcrEncoding::None.
Instead of open-coding these constraints in the validateColorSpaces()
function, create a new ColorSpace::adjust() function to centralize color
space validation and adjustment, and use it in validateColorSpaces().

Rectify the ColorSpace::Srgb to denote that it does not use
any Y'Cbcr encoding and uses full range.
The kernel on the other hand, recommends to use Rec601 as the encoding
for V4L2_COLORSPACE_SRGB. It is not very explicit but it can be
inferred that the kernel assumes V4L2_COLORSPACE_SRGB is a YUV-encoded
one. However, when the data is in RGB, no encoding is required (and
this is denoted by YcbcrEncoding::None in libcamera).
Hence, to be clear on the libcamera colorspace API, rectify the
ColorSpace::Srgb preset to use YcbcrEncoding::None and full range.

V4L2 has no "none" YCbCr encoding, and thus reports an encoding for all
formats, including RGB and raw formats. This causes the libcamera
ColorSpace to report incorrect encodings for non-YUV formats. Fix it by
overriding the encoding reported by the kernel to YCbCrEncoding::None
for non-YUV pixel formats and media bus formats.
Similarly, override the quantization range of non-YUV formats to full
range, as limited range isn't used for RGB and raw formats.

If a pointer-to-member is passed to the Signal::connect() function with
arguments that don't match the Signal type, the pointer-to-member
version of connect() will not match during template argument resolution,
but the functor version will. This results in a compilation error in the
BoundMethodFunctor class, due to the pointer-to-member not being a
functor and thus not being callable directly. The error messages are
quite cryptic. With the following error applied,

Doxyfile.in was generated using `doxygen -g` with Doxygen v1.8.14. This
has produced a file with all options supported by Doxygen at the time,
and a handful of them have then been modified to support libcamera's
needs, with most options retaining their default.
Some of the default options have been deprecated in newer Doxygen
releases, which led to warnings when generating the documentation. The
usual process to fix this is to update the configuration file with
`doxygen -u`. This creates a big diff due to the large number of changes
to default options, which isn't quite nice. Instead, let's just drop all
the default options and the comments, to produce a small and more
readable Doxyfile.in.

Implement color space support in the rkisp1 pipeline handler, in the
configuration generation, configuration validation and camera
configuration. As all the processing related to the color space is
performed in the part of the pipeline shared by all streams, a single
color space must cover all stream configurations. This is enforced
manually when generating the configuration, and with the
validateColorSpaces() helper when validating it.
Only the Y'CbCr encoding and quantization range are currently taken into
account, and they are programmed through the V4L2 color space API. The
primary colors chromaticities and the transfer function need to be
configured in the ISP parameters buffer, and thus conveyed to the IPA,
but the rkisp1 driver does not currently support tone mapping, so this
will be done later.

The main purpose of the script is to generate coefficient tables to

isn't trivial.

The JPEG color space is badly name, as the JPEG specification (ITU-T
T.81) doesn't define any particular color space:
The interchange format does not specify a complete coded image
representation. Application-dependent information, e.g. colour
space, is outside the scope of this Specification.
The JFIF specification (ITU-T T.871) is clearer as it requires ITU-R
BT.601 YCbCr encoding and a full quantization range:
The interpretations of Y, CB, and CR are derived from the E'Y, E'Cb,
and E'Cr signals defined in the 625-line specification of Rec. ITU-R
BT.601, but these signals are normalized so as to permit the usage of
the full range of 256 levels of the 8-bit binary encoding of the Y
component.
It however doesn't specify color primaries or a transfer function
explicitly. It only mentions the latter when describing the conversion
from YCbCr to RGB:
The inverse relationship for computing full scale 8-bit per colour
channel gamma pre-corrected RGB values (following Rec. ITU-R BT.601
gamma pre-correction and colour primary specifications) from YCbCr
colours (with 256 levels per component) can be computed as follows:
[...]
Given that ITU-R BT.601-5 (1995) didn't specify color primaries or a
transfer function, and that the later ITU-R BT.601-7 (2011) version
specifies color primaries for the 625-line variant that do not match
sRGB, the JPEG color space in libcamera is badly named. This is
confirmed by ITU-T T.871:
As this Recommendation | International Standard is based on the prior
informally-circulated JFIF version 1.02 specification that was
produced in 1992, which referenced Rec. ITU-R BT.601 (formerly CCIR
601), it references that specification for definition of the E'Y,
E'Cb, and E'Cr signals that correspond to the YCBCR values specified
herein. However, since the development of the prior JFIF version 1.02
specification, additional industry specifications have been developed,
Rec. ITU-R BT.601 has been updated, and common industry practice has
emerged which often follows the sYCC specification in IEC
61966-2-1/Amd.1. The difference between the use of the colour
interpretation specification in this Recommendation | International
Standard and that of the sYCC specification may be considered
negligible in practice.
Rename the color space to sYCC, as its definition matches the sYCC
standard, and indicate that it is typically used to encode JPEG images.

Wrap the CameraManager with a PyCameraManager class and move the related
code inside the new class.
This helps understanding the life times of the used-to-be global
variables, gets rid of static handleRequestCompleted function, and
allows us to simplify the binding code as the more complex pieces are
inside the class.
There should be no user visible functional changes.

We define -DLIBCAMERA_BASE_PRIVATE to get access to libcamera private
headers, but the correct way to do this is to have a meson dependency to
libcamera_private.

-C flag is supposed to affect only the camera that was previously
defined in the arguments. That's not the case, and, e.g.:
cam.py -c2 -C -c3
causes camera 3 to start capturing, but it stops after the initial
Requests have been completed.
Fix the issue by filtering out camera contexts that do not have -C
defined.

The message.h and mutex.h headers are not used in the libcamera public
API. Make them private to avoid there usage in applications, and to
prevent having to maintain them with a stable ABI.
As mutex.h is used by libcamerasrc, the GStreamer element must switch
from the libcamera_public to the libcamera_private dependency.
