fileio: make get_status_field() more generic
All users of get_status_field() expect the field pattern to occur in the beginning of a line, and the delimiter is ':'. Hardcode this into the function, and also skip any whitespace before ':' to support fields in files like /proc/cpuinfo. Add support for returning the full field value (currently stops on first whitespace). Rename the function so it's easier to ensure all callers switch to new semantics.
