clSetKernelArg can return an error due to lack of memory (for instance):
https://www.khronos.org/registry/cl/sdk/1.1/docs/man/xhtml/clSetKernelArg.html.
Thus this error must be propagated.

Currently should not trigger warnings, but adds robustness.

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):

ISO C restricts enumerator values to the range of int. Thus (for instance) 0x80000000
unfortunately does not work, and throws a warning with -Wpedantic on
clang 3.7.

This fixes it by using alternative expressions that result in identical
values but do not have this issue.

Tested with FATE.

av_gcd is now always defined regardless of input. This documents this
change in the "documented API". Two benefits (closely related):
1. The function is robust, and there is no need to worry about INT64_MIN, etc.

2. Clients of av_gcd, like av_reduce, can now be made fully correct. Currently,
av_reduce can trigger undefined behavior if e.g num is INT64_MIN due to
integer overflow in the FFABS. Furthermore, this undefined behavior is
completely undocumented, and could be a fuzzer's paradise. The FFABS was needed in the past as
av_gcd was undefined for negative inputs. In order to make av_reduce
robust, it is essential to guarantee that av_gcd works for all int64_t.
