db27029ce4 meson: Fix coding style when declaring arrays
The meson.build files mix array declarations with and without a space
after the opening and before the closing square bracket. The vast
majority of cases don't use spaces, so standardize on that.

While it it, fix indentation in a few places.

75a9aebee5 libcamera: pipelines: Use sensor ID as camera name
Use the CameraSensor ID as the camera name in pipelines that uses a
CameraSensors, this is done in preparation of turning the camera name
into an ID. The CameraSensor ID meets the requirements that will be put
on camera ID.

Before this change example of camera names:

* OF based systems
    ov5695 7-0036
    ov2685 7-003c

* ACPI based systems
    ov13858 8-0010
    ov5670 10-0036

* VIMC
    VIMC Sensor B

After this change the same cameras are:

* OF based systems
    /base/i2c@ff160000/camera@36
    /base/i2c@ff160000/camera@36

* ACPI based systems
    \_SB_.PCI0.I2C2.CAM0
    \_SB_.PCI0.I2C4.CAM1

* VIMC
    platform/vimc.0 Sensor B

93e72b695e libcamera: Move internal headers to include/libcamera/internal/
The libcamera internal headers are located in src/libcamera/include/.
The directory is added to the compiler headers search path with a meson
include_directories() directive, and internal headers are included with
(e.g. for the internal semaphore.h header)

  #include "semaphore.h"

All was well, until libcxx decided to implement the C++20
synchronization library. The __threading_support header gained a

  #include <semaphore.h>

to include the pthread's semaphore support. As include_directories()
adds src/libcamera/include/ to the compiler search path with -I, the
internal semaphore.h is included instead of the pthread version.
Needless to say, the compiler isn't happy.

Three options have been considered to fix this issue:

- Use -iquote instead of -I. The -iquote option instructs gcc to only
  consider the header search path for headers included with the ""
  version. Meson unfortunately doesn't support this option.

- Rename the internal semaphore.h header. This was deemed to be the
  beginning of a long whack-a-mole game, where namespace clashes with
  system libraries would appear over time (possibly dependent on
  particular system configurations) and would need to be constantly
  fixed.

- Move the internal headers to another directory to create a unique
  namespace through path components. This causes lots of churn in all
  the existing source files through the all project.

The first option would be best, but isn't available to us due to missing
support in meson. Even if -iquote support was added, we would need to
fix the problem before a new version of meson containing the required
support would be released.

The third option is thus the only practical solution available. Bite the
bullet, and do it, moving headers to include/libcamera/internal/.

7a653369cb licenses: License all meson files under CC0-1.0
In an attempt to clarify the license terms of all files in the libcamera
project, the build system files deserve particular attention. While they
describe how the binaries are created, they are not themselves
transformed into any part of binary distributions of the software, and
thus don't influence the copyright on the binary packages. They are
however subject to copyright, and thus influence the distribution terms
of the source packages.

Most of the meson.build files would not meet the threshold of
originality criteria required for copyright protection. Some of the more
complex meson.build files may be eligible for copyright protection. To
avoid any ambiguity and uncertainty, state our intent to not assert
copyrights on the build system files by putting them in the public
domain with the CC0-1.0 license.

256d0a4098 test: Use float values for brightness, contrast and saturation
Two tests use the brightness, contrast and saturation controls with
integer failures. They were not updated by commit eff4b1aa01 which
turned those controls into floats. This doesn't cause test failures as
the control API converts the value types. For correctness, update the
tests to use float values.

Fixes: eff4b1aa01 ("libcamera: controls: Reorder and update description of existing controls")
