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.

Useful to understand where and in what execution state a certain message
is generated. It is enabled only when optimizations are disabled, since
function names are not printed otherwise.

Softfloat will be used in implementation of AAC fixed point decoder.
This change is needed in order to more easily integrate ffmpegs softfloat in
already developed algorithm for AAC.

This will allow to copy the matrix as is and it is just cleaner to keep
the matrix in the same order specified by the mov standard (which is
also explicitly described in the documentation).
In order to preserve compatibility, flip the angle sign in the display API
av_display_rotation_set() and av_display_rotation_get(), and improve the
documentation mentioning the rotation direction.
Commit dfa9208074 ("mips/float_dsp: fix a bug in vector_fmul_window_mips")
fixed vector_fmul_window_mips by unrolling the loop only 4 times, but also
removed the outer C loop and replaced it with assembly branches and pointer
arithmetic. When submitting my 64-bit porting patch I missed this new
assembly which also needed porting.
This patch fixes a bus error in the fate-float-dsp test when run on 64-bit
mips.

Unfortunately android < api 21 (lollipop) doesn't have the sgidefs.h header,
the easiest way around this is to just use the preprocessor definitions from
gcc / clang.

When all the codepaths using manually set .arch/.fpu code is
behind runtime detection, the elf attributes should be suppressed.
This allows tools to know that the final built binary doesn't
strictly require these extensions.

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
