make fseek detect and produce an error for invalid whence arguments
this is a POSIX requirement. we previously relied on the underlying fd (or other backend) seek operation to produce the error, but since linux lseek now supports other seek modes (SEEK_DATA and SEEK_HOLE) which do not interact well with stdio buffering, this is insufficient. instead, explicitly check whence before performing any operations.
