Andreas Cadhalpun	51f6455285	imgutils: initialize palette padding bytes in av_image_alloc av_image_fill_pointers always aligns the palette, but the padding bytes don't (and can't) get initialized in av_image_copy. Thus initialize them in av_image_alloc. This fixes 'Syscall param write(buf) points to uninitialised byte(s)' valgrind warnings.

Maneesh Gupta	91305c6026	OpenCL: Fix ABI incompatibility issues AVOpenCLDeviceNode and AVOpenCLPlatformNode used fixed static buffer for holding the device and platform name. This patch modifies these structures to use pointers instead. The memory required to hold the names is now dynamically allocated, the size for which is determined by querying appropriate OpenCL runtime APIs.
