[PATCH 0/4] MR3836: Added definitions and initial tests for FileRenameInformationEx and FileLinkInformationEx

[Joel Holdsworth (＠jhol)]

This patch-set adds the definitions and struct modifications required to eventually implement `FileRenameInformationEx` and `FileLinkInformationEx`.

The initial tests are copies of the tests for `FileRenameInformation` and `FileLinkInformation`, but with the `ReplaceIfExists` field replaced with the equivalient `Flag` value: `FILE_RENAME_REPLACE_IF_EXISTS` or `FILE_LINK_REPLACE_IF_EXISTS` respectively.
