The commit trailers are checked as part of processing the commit message
with the newly introduced TrailersChecker.
This relies on the trailers property being correctly exposed by the
Commit object, and is implemented for the base Commit but not processed
for Amendment commits.
Refactor the trailer property handling to a helper function in the base
Commit class and make use of it with a newly added call to obtain the
existing Trailers from the most recent commit when using Amendment.

The Amendment commit class is derived from the StagedChanges class
(which in turn derives from the Commit base class), however there is no
code sharing between Amendment and StagedChanges other than the call to
initalise through the base Commit class.

If a Malformed trailer is identified the checkstyle script triggers a
RuntimeError and stops processing the rest of the commit.
A malformed trailer can be regarded as an issue in the commit and
reported as such using the same method as other faults identified by the
tool.
Convert the RuntimeError into a CommitIssue and continue processing
other trailers.

The libcamera git history contains numerous examples of incorrect commit
message trailers due to invalid trailer types (e.g. Change-Id), typos
and other small issues. Those went unnoticed through reviews, which
shows that an automated checker is required.
Add a trailers checker to checkstyle.py to catch invalid or malformed
trailers, with a set of supported trailers that match libcamera's commit
message practices. New trailer keys can easily be added later as new
needs arise.

Recent media-ctl versions include the framerate in the fmt property output:
- entity 37: ov5693 4-0036 (1 pad, 1 link)
type V4L2 subdev subtype Sensor flags 0
device node name /dev/v4l-subdev6
pad0: Source
[fmt:SBGGR10_1X10/2592x1944@1/30
crop.bounds:(16,6)/2592x1944
crop:(16,6)/2592x1944]
-> "ipu3-csi2 1":0 [ENABLED]
This resulted in $sensor_size getting set to: "2592x1944@1 30", which
causes the script to fail.
Fix this by:
1. Replacing the gsub() to remove the '/' between e.g. SBGGR10_1X10
and 2592x1944 with a sub() so that only that first '/' gets replaced
(resulting in a $sensor_size of "2592x1944@1/30" instead).
2. Adding a new sub() to remove the @1/30 suffix.

The previous attempt to fix git version parsing in commit d34cefad1791
("meson: Fix git version parsing") was too naive, and didn't take into
account cases where the libcamera git version contains no or multiple
'+' signs.
Fixing this is more complex than a one-liner change, as meson doesn't
support Python-style slicing of arrays or a length method on strings.
The simplest and most versatile option is to patch the version string in
the gen-version.sh script. Do so, and clarify the comments related to
version handling in meson.build.

Building libcamera as a subproject is failing when tracepoints are
enabled due to incorrectly managing the relative paths between the
source and build directory while generating tracepoint headers.
The previously used
path = output.replace('include/', '', 1)
logic is not sufficient to correctly determine the proper path when
libcamera is built as a subproject, and does not correctly handle the
relative paths, causing path to be processed as:
'subprojects/libcamera/include/libcamera/internal/tracepoints.h'.replace('include/', '', 1)
which evaluates to
'subprojects/libcamera/libcamera/internal/tracepoints.h'
so the tracepoints.h header file will try to include:
#define TRACEPOINT_INCLUDE "subprojects/libcamera/libcamera/internal/tracepoints.h"
which will fail.
Fix it by using Python's pathlib to calculate the relative path of the
output file with respect to the "include" directory of libcamera.
This has been tested with Pipewire. For non-subproject builds it should
generate the exact same path that was previously generated.

Currently, enums that are passed between pipeline handlers and their IPA
must be defined in a mojom file. However, there is a use case for
enum/flags to be defined in a C++ header, such that the enum can be used

Add Flags<E> as a supported type in the IPA interface.
It is used in mojom with the [flags] attribute. Any field or parameter
type E that is prefixed with the [flags] attribute will direct the code
generator to generate the type name "Flags<E>" and appropriate
serialization/deserialization code for Flags<E> instead of for E.
It is usable and has been tested in struct members, function input and
output parameters, and Signal parameters. This does not add support for
returning Flags as direct return values.
Additionally, the [scopedEnum] attribute can be used on enum
definitions, which will instruct the code generator to convert it to an
enum class instead of a raw enum.

Array controls specify the array size through the YAML 'size' element,
which stores a list of values, one per dimension. Variable-size arrays
currently use an empty 'size' list, which prevents describing the number
of dimensions of the array.
Improve this by using the same notation for fixed-size and variable-size
array controls. Dimensions that are not fixed are described as a string
instead of an integer, such as [n], [n,3] or [w,h]. The strings have
currently no special meaning, this may change in the future.

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.
