Use the removable attribute exposed by the USB device in sysfs to infer
if the camera is an external (when removable) or front (when
non-removable) camera. This is likely not perfect as the removable
attribute is derived from ACPI data which may not always be accurate,
and non-ACPI platforms likely report all devices as removable. Still,
this is a first step upon which a better method could be built.

The SensorSensitivity property is a scaling factor that describes how sensitive
the selected sensor mode is compared to other readout modes of the same sensor.
For example, a binned mode might have twice the sensitivity of the full
resolution mode, meaning you would get double the signal level for the same
exposure and gains.

gcc 10 and 11 produce an error when compiling libcamera in release mode:

../../src/libcamera/base/object.cpp:280:17: note: while referencing ‘msg’
280 | Message msg(Message::ThreadMoveMessage);

This seems to be a false positive, given that msg->type() can never be
equal to Message::InvokeMessage in Object::message() when called from
Object::notifyThreadMove(), as the message is created there with the
Message::ThreadMoveMessage type. The problem as been reported in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105400, but the error
nonetheless needs to be fixed without waiting for a new gcc release, and
a dynamic_cast does the job with a small additional runtime cost that
shouldn't be a big issue, given that moving objects between threads is a
rare operation.

The IPAIPU3 interface currently uses event-type based structures in
order to communicate with the pipeline-handler (and vice-versa).
Replace the event based structures with dedicated functions associated
to each operation.
The translated naming scheme of actions to signals are:
ActionSetSensorControls => setSensorControls
ActionParamFilled => paramsBufferReady
ActionMetadataReady => metadataReady
The translated naming scheme of events to dedicated functions are:
EventProcessControls => queueRequest()
EventStatReady => processStatsBuffer()
EventFillParams => fillParamsBuffer()
The dedicated functions are called from pipeline-handler to the IPA
using IPC. These functions run asynchronously and when completed,
the IPA emits the respective signals as stated above in the translated
naming scheme.
The EventProcessControls is translated to queueRequest() to bring
symmetry to the IPU3 interface with other IPA interfaces.

The original use of RPi::Stream::reset() was to clear the external flag state
and free/clear out the framebuffers for the stream. However, the latter is now
done through PipelineHandlerRPi::configure(). Rework
PipelineHandlerRPi::configure() to call RPi::Stream::setExternal() instead of
RPi::Stream::reset() to achieve the same thing.
Repurpose RPi::Stream::reset() to instead reset the state of the buffer handling
logic, where all internally allocated buffers are put back into the queue of
available buffers. As such, rename the function to RPi::Stream::resetbuffers().
This resetbuffers() is now called from PipelineHandlerRPi::start(), allowing the
pipeline handler to correctly deal with start()/stop()/start() sequences and
reusing the buffers allocated on the first start().

Currently, all framebuffer allocations get freed and cleared on a stop in
PipelineHandlerRPi::stopDevice(). If PipelineHandlerRPi::start() is then called
without an intermediate PipelineHandlerRPi::configure(), it will re-allocate and
prepare all the buffers again, which is unnecessary.
Fix this by not freeing the buffer in PipelineHandlerRPi::stopDevice(), but
insted doing it in PipelineHandlerRPi::configure(), as the buffers might have
to be resized.
Add a flag to indicate that buffer allocations need to be done on the next
call to PipelineHandlerRPi::start().
