7c3831d2d1 libcamera: vimc: Fill stride and frameSize at config validation
Fill the stride and frameSize fields of the StreamConfiguration at
configuration validation time instead of at camera configuration time.
This allows applications to get the stride when trying a configuration
without modifying the active configuration of the camera.

56c99424ed libcamera: pipeline: Replace explicit DRM FourCCs with libcamera formats
Use the new pixel format constants to replace usage of macros from
drm_fourcc.h.

The IPU3 pipeline handler still uses DRM FourCCs for IPU3-specific
formats that are not defined in the libcamera public API.

As the only usage of IPAManager::instance() is by the pipeline handlers

f934fd1cb9 libcamera: Move IPA headers from include/ipa/ to include/libcamera/ipa/
The IPA headers are installed into $prefix/include/libcamera/ipa/, but
are located in the source tree in include/ipa/. This requires files
within libcamera to include them with

 #include <ipa/foo.h>

while a third party IPA would need to use

 #include <libcamera/ipa/foo.h>

Not only is this inconsistent, it can create issues later if IPA headers
need to include each other, as the first form of include directive
wouldn't be valid once the headers are installed.

Fix the problem by moving the IPA headers to include/libcamera/ipa/.

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/.

5888918153 libcamera: vimc: Adjust crop rectangle
Since the Linux kernel commit:
69e39d40587b ("media: vimc: Implement get/set selection in sink")
the crop rectangle on the VIMC scaler sink pad needs to be
reset to match the requested format to avoid hitting a pipeline format
misconfiguration when the applied format is larger than the one
set in a previous capture session.

As the V4L2 specification is not clear on what the correct behaviour
is, if the crop rectangle should be reset automatically or not on a
set_fmt operation, momentary fix the pipeline handler to please the
driver and manually reset the crop rectangle.

eff4b1aa01 libcamera: controls: Reorder and update description of existing controls
Group AE, AWB, etc. controls together for accessibility.

Update descriptions for Contrast, Brightness, and Saturation controls.

Update the uvcvideo and vimc pipeline handlers to use the new
brightness, contrast and saturation units. UVC has no explicit units for
those controls, so map them with a best effort heuristic. For VIMC,
hardcode the control range based on knowledge of the driver
implementation for simplicity.
