We build libcamera with -Wno-unused-parameter and this doesn't cause
much issue internally. However, it prevents catching unused parameters
in inline functions defined in public headers. This can lead to
compilation warnings for applications compiled without
-Wno-unused-parameter.
To catch those issues, remove -Wno-unused-parameter and fix all the
related warnings with [[maybe_unused]].

The IPU3CameraConfiguration::streams_ field was used to keep an
association between the StreamConfiguration and the assigned streams
before CameraConfiguration::setStream() was called at configure() time.
The stream assignment was based on the order in which elements were
inserted in the vector, implementing a fragile association between
streams and their intended configurations.
As it is now possible to assign streams at validation time, there is no
need to keep that association in place, and the streams_ vector is now
unused.
Remove it and the associated accessor method from the
IPU3CameraConfiguration class.

Remove the adjustStream() and assignStream() methods, and perform stream
adjustment and assignment while iterating the StreamConfiguration
items.
The adjustStream() implementation had some arbitrary assumption, like
the main output having to be as large as the sensor resolution, and did
not take into account the different alignment requirements between the
main output and the viewfinder output.
The assignStream() implementation also assumes only full-size streams
can be produced by the main output, and having it as a separate function
prevents adjusting streams according to which output they are assigned.
Blend the two implementation in a single loop and perform the required
stream adjustment and assignment in one go.
As streams are now assigned at validate() time, remove the same
operation from the configure() function.

The current implementation of the Camera::configure() method zeroes the

the pipeline handler configure() operation, just after the

This discards the stream assignment performed at pipeline hander
validation time, requiring platforms that need to perform that early
assignment to maintain the association in place with custom data
structures.
To allow pipeline handlers to use StreamConfiguration::setStream() at
validate() time, zero the stream assignment before calling validate().
