René Scharfe 39c575c969 config: simplify parsing of unit factors ...

Just return the value of the factor or zero for unrecognized strings
instead of using an output reference and a separate return value to
indicate success.  This is shorter and simpler.

It basically reverts that function to before c8deb5a146 ("Improve error
messages when int/long cannot be parsed from config", 2007-12-25), while
keeping the better messages, so restore its old name, get_unit_factor(),
as well.
