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`.

The switch statement checks `roles.size()` with cases for 1 and 2,
so in the `default` branch, `role.size() > 2`, i.e. it is always
different from 1, so the check is unnecessary.

A new warning has been introduced to gcc-13 that produces a false
positive on the cam file sink object:
src/cam/file_sink.cpp:92:45: error: possibly dangling reference to a temporary [-Werror=dangling-reference]
92 | const FrameMetadata::Plane &meta = buffer->metadata().planes()[i];
| ^~~~
src/cam/file_sink.cpp:92:81: note: the temporary was destroyed at the end of the full expression '(& buffer->libcamera::FrameBuffer::metadata())->libcamera::FrameMetadata::planes().libcamera::Span<const libcamera::FrameMetadata::Plane>::operator[](i)'
92 | const FrameMetadata::Plane &meta = buffer->metadata().planes()[i];
| ^
cc1plus: all warnings being treated as errors
Workaround this issue by refactoring the code to take a local const
copy of the bytesused value, rather than a local const reference to the
plane.

There is no need to wrap DRM::AtomicRequest in std::unique_ptr<>
in KMSSink::start(). Remove it so that the syntax becomes similar to
what we have in KMSSink::stop().
No functional changes intended.

Instead of having bool return type and an out parameter, use
std::optional<libcamera::StreamRole> to return from
StreamKeyValueParser::parseRole().
Meanwhile at it, re-word an existing comment to make it lucid.

In the simple capture tests, in the capture functions, the Requests were
auto-deallocated by the function going out of scope after the test
completed. However, before the end of the scope, the Framebuffers that
the Requests referred to were manually freed. Thus when the Requests
were deallocated, they tried to cancel their Framebuffers, which involve
setting the status to cancelled, which obviously causes a segfault
because the Framebuffers had already been freed.
Fix this by moving the list of Requests to a member variable and
deallocating them before deallocating the Framebuffers at stop() time.

The parameter 'request' is only used in an assert. assert is only defined
for debug builds and release builds will not use the parameter, resulting
in warnings messages only for non-debug builds.

Multiple source files in the src/apps/cam/ directory are used by cam,
qcam and lc-compliance. They are compiled separately for each
application. Move them to a new src/apps/common/ directory and compile
them in a static library to decrease the number of compilation
operations.

When libtiff-4 is not found, the private camera_ member of the FileSink
class is set but never used. This causes a compilation error with clang:
In file included from ../../src/apps/cam/file_sink.cpp:19:
../../src/apps/cam/file_sink.h:39:27: error: private field 'camera_' is not used [-Werror,-Wunused-private-field]
const libcamera::Camera *camera_;
Fix by making the camera_ member field conditional on HAVE_TIFF.
