If opj_image_create fails to allocate an image it returns NULL, which
causes a segmentation fault at 'img->x0 = 0'.

The only need to be listed if they are to be used in ifdefs from

configure don't need to be exported.

This fixes dxva2 detection (i.e. correctly realizes that it isn't
available) for WinRT, where dxva2api.h does exist, but these definitions
are omitted (when targeting the API subsets).

Ideally we should rather check for e.g. DXVA2_ConfigPictureDecode,
but configure might fail to find that definition due to _WIN32_WINNT
not being set to the right value during configure. (libavcodec/dxva2.h
manually overrides the _WIN32_WINNT define.)

This allows removing hardcoded --disable-dxva2 from such build
configurations.
