Sub-class the Stream class with an IPU3-specific implementation and
create each IPU3 camera with two streams: 'output' and 'viewfinder'
which represent the video streams from main and secondary ImgU output
respectively.
Rework stream configuration to handle the two video streams 'output'
and 'viewfinder' separately.
As the IPU3 driver requires viewfinder and stat video nodes to be
started not to stall ImgU processing, configure 'output', 'viewfinder'
and 'stat' regardless of the user-requested active streams.

When logging the camera configuration, the same ostringstream instance
is used to assemble a message describing configuration of all the
configured streams.
After the first stream configuration has been assembled, the use of
std::hex modifies the ostringstream basefield, causing all successive
integers values inserted in the stream to be expressed as hexadecimals.
Fix that by resetting the stream's basefield to decimal, before
assembling a stream configuration description.

Since commit: 4e1dc9004fca ("libcamera: stream: Make Stream inheritable")
the private members of the Stream class have been turned into protected,
to allows subclasses to access them.
As Doxygen generates documentation for protected members (but not for
private memebers), add documentation to the stream class for the
'bufferMap_' and 'configuration_' members.

As of now, PipelineHandler::allocateBuffers() is called once for each

streams, and ask them to loop over them to perform per-streams

To properly support both multiple streams and stream usages the library
must provide a method to map the stream usages to the returned streams
configurations. Add a camera configuration object to handle this
mapping.
Applications can iterate over the returned camera configuration to
retrieve the streams selected by the library in the same order as the
usages it provided to the library.
Applications can use the operator[] to retrieve the stream pointer and
the stream configuration. Using a numerical index retrieves the stream
pointer, the numerical indexes corresponds to the insertion order of
usages in the CameraConfiguration, using the stream pointer retrieves
the stream's configuration.

Instead of requesting the default configuration for a set of streams
where the application has to figure out which streams provided by the
camera is best suited for its intended usage, have the library figure
this out by using stream usages.
The application asks the library for a list of streams and a suggested
default configuration for them by supplying a list of stream usages.
Once the list is retrieved the application can fine-tune the returned
configuration and then try to apply it to the camera.
Currently no pipeline handler is prepared to handle stream usages but
nor did it make use of the list of Stream IDs which was the previous
interface. The main reason for this is that all cameras currently only
provide one stream each. This will still be the case but the API will be
prepared to expand both pipeline handlers and applications to support
streams usages.
