avfilter/transform: Stop exporting internal functions
...
avfilter_transform, avfilter_(add|sub|mult)_matrix are not part of the
public API (transform.h is not a public header), yet they are currently
exported because of their name. This commit changes this:
avfilter_transform is renamed to ff_affine_transform; the other
functions are just removed as they have never been used at all.

lavfi/deshake: fix deshake crash issue.
...
Fixes ticket #7441 .
for block contrast calculate, the block is like this:
|<---------------- stride-----------------------|
+-----------------------------------------------> X
|
| w = 16
| (cx,cy)+------+
| | |
|h=blocksize| |
| | |
| +------+
V
Y
so we calc the block contrast use:
(cy + y) * stride + (cx + x)

lavu,lavfi,ffmpeg: Remove experimental OpenCL API
...
This was added in early 2013 and abandoned several months later; as far as
I can tell, there are no external users. Future OpenCL use will be via
hwcontext, which requires neither special OpenCL-only API nor global state
in libavutil.
All internal users are also deleted - this is just the unsharp filter
(replaced by unsharp_opencl, which is more flexible) and the deshake filter
(no replacement).

all: use FFDIFFSIGN to resolve possible undefined behavior in comparators
...
FFDIFFSIGN was created explicitly for this purpose, since the common
return a - b idiom is unsafe regarding overflow on signed integers. It
optimizes to branchless code on common compilers.
FFDIFFSIGN also has the subjective benefit of being easier to read due
to lack of ternary operators.
Tested with FATE.
Things not covered by this are unsigned integers, for which overflows
are well defined, and also places where overflow is clearly impossible,
e.g an instance where the a - b was being done on 24 bit values.

avfilter/vf_deshake: replace qsort with AV_QSORT
...
qsort is called indirectly in filter_frame, suggesting its performance
criticality. AV_QSORT is substantially faster due to the inlining of the
comparison callback. Thus, the increase in performance should be worth
the increase in binary size.
This optimization is just a low hanging fruit. The trac ticket 1430 is
a request for an improved deshake filter.
Sample benchmark (x86-64, Haswell, GNU/Linux):
File: original from https://trac.ffmpeg.org/ticket/1430
command: ffmpeg -stream_loop 8 -i file.webm -vf deshake=rx=64:ry=64 -f null -

avfilter/vf_deshake: use a void * comparator for consistency
...
For generality, qsort uses a comparator whose elements are void *. This
makes the comparator have such a form, and thus makes the void * cast of
the comparator pointer useless. Furthermore, this makes the code more
consistent with other usages of qsort across the codebase.
