The MediaDevice class will be the entry point to hot-unplug, as it
corresponds to the kernel devices that will report device removal
events. The class will signal media device disconnection to pipeline
handlers, which will clean up resources as a result.
This can't be performed synchronously as references may exist to the
related Camera objects in applications. The MediaDevice object thus
needs to be reference-counted in order to support unplugging, as
otherwise pipeline handlers would be required to drop all the references
to the media device they have borrowed synchronously with the
disconnection signal handler, which would be very error prone (if even
possible at all in a sane way).
Handle MedieDevice instances with std::shared_ptr<> to support this.

The Camera class is explicitly reference-counted to manage the lifetime
of camera objects. Replace this open-coded implementation with usage of
the std::shared_ptr<> class.
This API change prevents pipeline handlers from subclassing the Camera
class. This isn't deemed to be an issue. Mark the class final to make
this explicit.

Cameras are listed through a double indirection, first iterating over
all available pipeline handlers, and then listing the cameras they each
support. To simplify the API make the pipeline handlers register the
cameras with the camera manager directly, which lets the camera manager
easily expose the list of all available cameras.
The PipelineHandler API gets simplified as the handlers don't need to
expose the list of cameras they have created.

Create two arrays, to contain public and internal test targets, and use
the foreach iterators to automatically generate test output targets for
each entry in each array.
The public tests array is linked only against public libcamera headers,
while tests declared in the internal_tests will have access to
non-public API headers from within the libcamera sources.

Calling the cleanup() function in the base class Test destructor only
calls the base class empty cleanup() function, not the overloaded one.

In order to match the directory structure of traditional projects,
rename the top-level lib/ directory to src/libcamera/. Other libraries
developed as part of the project will later find a home in src/.
Split the libcamera header files in three categories: public headers
describing the public API in include/libcamera/, internal headers
describing the internal API in src/libcamera/include/, and private
headers local to one or a small number of compilation units along the
corresponding .cpp files. As no internal header exists yet the
src/libcamera/include/ directory is created empty as the build system
would fail otherwise.
