* Add latest mkwinsyscall file Copied file from: https://github.com/golang/sys/blob/bc2c85ada10aa9b6aa9607e9ac9ad0761b95cf1d/windows/mkwinsyscall/mkwinsyscall.go Signed-off-by: Hamza El-Saawy <hamzaelsaawy@microsoft.com> * Update to match hcsshim mksyscall_windows Added hr error return type, cmdline flags for winio import, utf16, and sorting. Generated file has build constrain comment. Input files can be specified with a glob pattern. Signed-off-by: Hamza El-Saawy <hamzaelsaawy@microsoft.com> * PR: update comment, use glob Signed-off-by: Hamza El-Saawy <hamzaelsaawy@microsoft.com>
