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.
Fixes: 4e1dc9004fca ("libcamera: stream: Make Stream inheritable")

Include the header file corresponding to the source file in the very
first position. This complies with the Google C++ coding style
guideliens, and helps ensuring that the headers are self-contained.
Three bugs are already caught by this change (missing includes or
forward declarations) in device_enumerator.h, event_dispatcher_poll.h
and pipeline_handler.h. Fix them.

The documentation style for the Doxygen comment blocks is inconsistent
in the library. Document the expectations and update all existing
comment blocks to match.

In preparation of reworking how a default configuration is retrieved
from a camera add stream usages. The usages will be used by applications
to describe how they intend to use a camera and replace the Stream IDs
when retrieving default configuration from the camera using
streamConfiguration().

Add a cache of the active stream configuration to the stream object.
This cache is to be updated from the Camera object and can be accessed
read only from both the application and pipeline handlers.

The camera needs to be configured with the number of buffers required to
satisfy the applications use case. While the application can request any
number of buffers, the pipeline must take the constraints of the Linux
driver into consideration.

Add an initial StreamConfiguration implementation to hold configuration
data for a single stream of a Camera. In its current form not many
configuration parameters are supported but it's expected the number of
options will grow over time.
At this stage the pixel format is represented as an unsigned int to
allow for easy mapping to the V4L2 API. This might be subject to change
in the future as we finalize how libcamera shall represent pixel
formats.

Add an initial Stream implementation. The idea is that once capability
support is added to the library each stream will describe its
capabilities using this class. An application will then select one or
more streams based on these capabilities and use them to configure the
camera and capture.
At this stage the Stream class is empty as capabilities are yet to be
added. The class is still useful as it will be used to communicate how
many streams a Camera object provides.
