Make the BufferWriter class inherit from FrameSink, and use the
FrameSink API to manage it. This makes the code more generic, and will
allow usage of other sinks.

To allow testing capture from multiple cameras concurrently, turn the
--camera option into an array option, and create one CameraSession per
specified camera. The code is adapted to iterate over the sessions
vector instead of handling a single session. Thanks to all the
refactoring previously performed, changes are minimal.

To prepare for multi-camera support, extend the file naming scheme for
captured frames to include the camera index in addition to the stream
name and frame number.

Use the new hierarchical options feature of the option parser to turn
camera-related option (--capture, --file, --stream, --strict-formats and
--metadata) into children of the --camera option. As an added bonus, we
don't need to check anymore if a camera has been specified when capture
is requested, as that's now enforced by the option parser.
This change prepares for support of multiple cameras.

The three CamApp functions listControls(), listProperties() and
infoConfiguration() operate on a camera. They would thus be better
placed in the CameraSession class. Move them there. As they now have no
error to return anymore, make them void functions.

Continue moving towards making the CameraSession class the central point
to handle a camera by moving the camera acquire operation. A new
CameraSession::camera() function is needed to allow access to the camera
from CamApp.

Creating a configuration for a camera is an operation that logically
belongs to the CameraSession class. Move it there.

Move the local CameraSession variable from the CamApp::run() function to
a member variable of the CamApp class, created in CamApp::init(). This
is a first step towards moving code to the CameraSession class.

Don't pass the event loop to the CameraSession constructor, as passing
this global object explicitly isn't a design that can scale.

Rename the Capture class to CameraSession, to prepare for multi-camera
support that will gather more camera-related operations than capture in
that class.
While at it, remove an unneeded blank line.
