This makes it a bit easier to profile different setups. Moreover, the sensor
size is now much larger but by default is reduced to the old 512x512 window.

The combination of CONSTRUCT_ONLY and READWRITE causes a) unnecessary warnings
and b) confuses the TANGO server down below (see SCHNEIDE-661). Since adapting
the mock camera size and bitdepth at run-time is not a high-priority feature, we
reverted that change. In the future and if still required this should be solved
through either compile-time defines or an environment variable.

ANKA plugins are developed and distributed separately like other plugins
depending on vendor SDKs.

The bundled plugins use libuca version as their version and depend on it directly.
This ensures that they always match the libuca version and makes versioning more
transparent for the end users.

Using the readout interface will prefix the frame counter in the image with a 'B' followed by its own specific counter for readout-calls

Changed sensor-width, sensor-height and sensor-bitdepth to construct only
Added uca_camera_pspec_set_writable

mock: allow characterization at construction time
Its now possible to set sensor-width, sensor-height and sensor-bitdepth at construction time
Creation of random data is now controlled by a property and can be set while recording
