ab623b4738 cam: Rename BufferWriter to FileSink
Rename the BufferWriter class to FileSink to establish a common naming
scheme for all sinks.

02001fecb0 cam: Turn BufferWriter into a FrameSink
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.

e0704e97ea cam: Support using multiple cameras concurrently
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.

721f4b03d8 cam: Add camera index to file name of capture frames
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.

7dab1fa58f cam: Make camera-related options sub-options of OptCamera
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.

66c955648f cam: Move printing of camera information to CameraSession class
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.

8519df23a9 cam: Move camera acquire to the CameraSession class
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.
