Provide a factory for DeviceEnumerator objects. Depending on which libraries are available there will be different ways to enumerate information in the system. This factory hides this from the rest of the library.

2018-12-21tests: call the derived Test class cleanup() functionNiklas Söderlund
Calling the cleanup() function in the base class Test destructor only calls the base class empty cleanup() function, not the overloaded one. This results in tests not cleaning up after themself. Solve this by explicitly calling the cleanup() function from execute(). This was discovered while running valgrind on tests where objects where allocated in init() and freed in cleanup().

2018-12-19libcamera: include: Import media.h from Linux v4.19Jacopo Mondi
In order to avoid depending on system headers that may be outdated compared to the kernel version available at runtime, import the Linux kernel headers related to the APIs that libcamera requires a recent version of. This allows libcamera to use the latest kernel APIs even when compiled on older systems. The library must of course test at runtime whether those APIs are available and fallback to older APIs in order to support older kernels. Import media.h for the recent media controller APIs. The file is extracted verbatim from kernel v4.19. Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>

2018-12-12libcamera: log: Fix Doxygen documentationLaurent Pinchart
Now that the documentation can be compiled, Doxygen throws a few warnings due to incorrect enum field naming. Fix it. The \file block needs to be named after the header file in order for Doxygen to document any global function, variable, typedef or enum defined in the header (as documented in the Doxygen manual under the \file command). We thus need to use log.h as the file name. No \file block is needed for the .cpp file, as we don't want to generate documentation for internal private globals.

Extend the documentation build system to automatically generate documentation from source code using Doxygen.
