Bugs: MESOS-8646

Repository: mesos


Changed flags to CreateFile to support Windows symlink path resolution.

Diffs (updated)

  3rdparty/stout/include/stout/internal/windows/reparsepoint.hpp 858b3c7c27e95b9cf46a7457c1aaa05a0e19188d

I encountered a permissions error stating "The process cannot access the file because it is
being used by another process." when attempting to download stderr/stdout from a task running
on a Windows agent, or when attempting to download the mesos agent log on a Windows agent.

After some very helpful information from Andy and Akash, I made this change and confirmed
it fixed this issue with the task/agent logs.

I also ran the automated tests on Windows and all tests pass.

I did not test this on Linux, but because this file is compiled only on Windows, it shouldn't
be necessary.
