win32: optimize parameters for the CreateFile call in _getfileinfo Set dwDesiredAccess to 0 instead of GENERIC_READ. Zero is enough for querying the file metadata. We don't even need to access the -contents- of the file. Set dwShareMode to FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE instead of the overly restrictive FILE_SHARE_READ. There is no need to cause write or delete accesses by other processes to fail while we are querying file metadata. See http://msdn.microsoft.com/en-us/library/aa363858(v=vs.85).aspx
