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.

Srikanth G 0f2359b869 avutil/opencl: is_compiled flag not being cleared in av_opencl_uninit 
When OpenCL kernels are compiled, is_compiled flag is being set for each
kernel. But, in opencl uninit, this flag is not being cleared.
This causes an error when an OpenCL kernel is tried on different OpenCL
devices on same platform.

Here is the patch with a fix
