tdf#116420: Windows: Test if a filepath redirects to a WebDAV resource
In Windows, filesystem redirectors can map WebDAV resources to UNC paths, or to drive-based "local" paths; so a WebDAV URI of the form "http://WebDADServer/root/directory/File.ext" may be accessed using "\\WebDADServer\root\directory\File.ext" or "Z:\directory\File.ext". When using these paths, failure to create a lockfile aside the opened document should not be considered an error; so this patch checks for this. Regression from commit 6ca3b3648e25ae9d4d2d29a0df83349198ec3f5e.
