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.

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.
Fix this by flagging the parameter as 'maybe_unused'.

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.

libtiff is a shared dependency between cam and qcam, move it to
src/apps/. The shared dependency will be used to condition compilation
of source files in an upcoming application static library.

The cam and qcam test application share code, currently through a crude
hack that references the cam source files directly from the qcam
meson.build file. To prepare for the introduction of hosting that code
in a static library, move all applications to src/apps/.
