Allow parse_size to return 0.

We will shortly introduce --data-offset= which is allowed to
be zero.  We will want to use parse_size() so it needs to be
able to return '0' without it being an error.

So define INVALID_SECTORS to be an impossible value (currently '1')
and return and test for it consistently.
