libcamera v0.1.0

ABI Compliance:

abi-compliance-checker reports 99% binary compatibility and 81.4% source
compatibilty between version 0.0.5 and 0.1.

 - Binary compatibility: 99%
 - Source compatibility: 81.4%
 - Total binary compatibility problems: 4, warnings: 2
 - Total source compatibility problems: 165, warnings: 7

Now that we have funtional ABI validation, the soname has been updated from
libcamera.so.0.0.5 to libcamera.so.0.1.

Future releases will now maintain the same soname until an ABI breakage is
detected to reduce the repackaging and rebuilding of other components that may
use libcamera. The abi-compatibility report can now be generated with the new
utility './utils/abi-compat.sh'.

Key differences here are due to preventing the installation of internal and
private headers in the packaging process, and most of this API compatibility
should not be visible to applications with the exception of:

- Camera::generateConfiguration ( StreamRoles const& roles )

  The StreamRoles type definition has been removed. This is now handled as a
  Span<StreamRole> to prevent unnecessary allocations and copies.

- CameraManager::addCamera ( std::shared_ptr<struct Camera> camera, std::vector<unsigned long>const& devnums )
- CameraManager::get ( dev_t devnum )
- CameraManager::removeCamera ( std::shared_ptr<struct Camera> camera )

  These functions of the CameraManager were for use exclusively by the V4L2
  adaptation layer, and not intended for use by applications. This has now been
  reworked to use the new SystemDevices and the redundant functions removed.

The ABI/API breakages have been introduced by:

  5ca0c9276f28 ("libcamera: CameraManager: Remove ::get(dev_t)")
  26a4b83d1b94 ("libcamera: Remove `StreamRoles` alias")
