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.
