4746653466 avutil/file_open: avoid file handle inheritance on Windows 
Avoids inheritance of file handles on Windows systems similar to the
O_CLOEXEC/FD_CLOEXEC flag on Linux.

Fixes file lock issues in Windows applications when a child process
is started with handle inheritance enabled (standard input/output
redirection) while a FFmpeg transcoding is running in the parent
process.

Links relevant to the subject:

https://msdn.microsoft.com/en-us/library/w7sa2b22.aspx

Describes the _wsopen() function and the O_NOINHERIT flag. File handles
opened by _wsopen() are inheritable by default.

https://msdn.microsoft.com/en-us/library/windows/desktop/ms682425%28v=vs.85%29.aspx

Describes handle inheritance when creating new processes. Handle
inheritance must be enabled (bInheritHandles = TRUE) e.g. when you want
to pass handles for stdin/stdout via lpStartupInfo.

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.

7910a2c269 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
