729466dc68 libavutil/softfloat: Add test case for av_add_sf 
Recently normalization (av_normalize_sf) of output was added to av_add_sf.
This normalization is used for better precision for small values and the
purpose of this (quite simple) test case is to test difference between double
and softfloat.

The values used are tailored to maximally highlighte problem with precison when
normalization is not used.

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.

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.
