When packaging libcamera, distributions may break IPA module signatures
if the packaging process strips binaries. This can be fixed by resigning
the modules, but the process is error-prone.
Add a command line ipa-verify utility that tests the signature on an IPA
module to help packagers. The tool takes a single argument, the path to
an IPA module shared object, and expects the signature file (.sign) to
be in the same directory.
In order to access the public key needed for signature verification, add
a static function to the IPAManager class. As the class is internal to
libcamera, this doesn't affect the public API.

Now that `Camera::generateConfiguration()` takes a `libcamera::Span`
of `StreamRole`, remove the `StreamRoles` type, which was an alias
to `std::vector<libcamera::StreamRole>`.
The removal has two reasons:
- it is no longer strictly necessary,
- its presence may suggest that that is the preferred (or correct)
way to build/pass a list of `StreamRole`.

Change the parameter type of `generateConfiguration()` from `const std::vector&`
to `libcamera::Span`. A span is almost always preferable to a const vector ref
because it does not force dynamic allocation when none are needed, and it allows
any contiguous container to be used.
A new overload is added that accepts an initializer list so that
cam->generateConfiguration({ ... })
keeps working.
There is no API break since a span can be constructed from a vector
and the initializer list overload takes care of the initializer lists,
but this change causes an ABI break.

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.

Commit 6f6e1bf704fe ("libcamera: camera_sensor: Apply flips at

to apply vertical/horizontal flips on the sensor based on the
supplied Transform. To pass the Transform to the function the
V4L2SubdeviceFormat structure has been augmented with a Transform

However as the newly added Transform is not used at all in the

Fix that by removing the transform field from V4L2SubdeviceFormat
and pass it as an explicit parameter to CameraSensor::setFormat().

Menu controls without a list of menu items are no longer added as a

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.

Each declaration of a LogCategory will create a new LogCategory, and
will be stored in an unordered_set Logger::categories_. This means that
when a plugin .so is unloaded and loaded, as happens when destructing
and creating a CamereManager, we'll get duplicate categories.
The Logger::registerCategory docs say "Log categories must have unique
names. If a category with the same name already exists this function
performs no operation.". The code does not comply with this.
We solve the issue with two changes:
Change the unordered_set to a vector for simplicity, as there's no need
for an unordered_set.
Instead of using the LogCategory constructor to create new categories in
_LOG_CATEGORY() macro, use a factory method. The factory method will
return either an existing LogCategory if one exists with the given name,
or a newly created one.

LogCategory just stores the char * that was given to it in the
constructor, i.e. it refers to memory "outside" LogCategory. If the
LogCategory is defined in a .so that is unloaded, then it leads to the
LogCategory pointing to freed memory, causing a crash.
Fix this by taking a copy of the name by using a std::string instead of
just storing the pointer.

The overloaded deserializers functions that called the main deserializer
function using iterators used cbegin() but end() instead of cend(). Make
all of these use cend() instead.

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
in a component other than the pipeline handler and its IPA.
To support this, add support for the skipHeader attribute for enums.
Like structs, it is only allowed in core.mojom.

For the purpose of testing serializing/deserializing Flags in function
parameters, add an enum class TestFlags and Flags<TestFlags> to some
function parameters, both for input and output and Signals.
While at it, update the ipa_interface_test.
