d258025da7 libcamera: camera_manager: Add environment variable to order pipelines match
To match the enumerated media devices, each registered pipeline handler
is used in no specific order. It is a limitation when several pipelines
can match the devices, and user has to select a specific pipeline.

For this purpose, environment variable LIBCAMERA_PIPELINES_MATCH_LIST is
created to give the option to define an ordered list of pipelines to
match on.

LIBCAMERA_PIPELINES_MATCH_LIST="<name1>[,<name2>[,<name3>...]]]"

Example:
LIBCAMERA_PIPELINES_MATCH_LIST="rkisp1,simple"

626172a16b libcamera: Drop file name from header comment blocks
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.

5ca0c9276f libcamera: CameraManager: Remove ::get(dev_t)
The CameraManager::get(dev_t) implementation was provided only for the
V4L2 Adaptation layer. This has now been replaced with the use of the
public SystemDevices property.

Remove the deprecated function entirely, along with the camerasByDevnum_
map which was only used to support this functionality.

This is a clear (and intentional) breakage in both the API and ABI.

b9113a8626 libcamera: pipeline: Register device numbers with camera
Register the identified device numbers with each camera as the
SystemDevices property.

This facilitates camera daemons or other systems to identify which
devices are being managed by libcamera, and can prevent duplication of
camera resources.

As the SystemDevices property now provides this list of devices, use it
directly from within the CameraManager when adding a Camera rather than
passing it through the internal API.

75ddd20209 libcamera: camera_manager: Move {add,remove}Camera to internal
The CameraManager exposes addCamera and removeCamera as public API
calls, while they should never be called from an application. These
calls are only expected to be used by PipelineHandlers to update the
CameraManager that a new Camera has been created and allow the Camera
Manager to expose it to applications.

Remove the public calls and update the private implementations such that
they can be used directly by the PipelineHandler through the internal
CameraManager::Private provided by the Extensible class.

7144fe6f9c libcamera: camera_manager: Move private implementation to internal
The CameraManager makes use of the Extensible pattern to provide an
internal private implementation that is not exposed in the public API.

Move the Private declaration to an internal header to make it available
from other internal components in preperation for reducing the surface
area of the public interface of the CameraManager.
