Rename die_info::sibling to die_info::next

I want to add support for C++ foreach iteration over DIE siblings.

I considered writing a custom iterator for this, but it would be
largely identical to the already-existing next_iterator.  I didn't
want to duplicate the code...

Then I tried parameterizing next_iterator by having it take an
optional pointer-to-member template argument.  However, this would
involve changes in many places, because currently a next_iterator can
be instantiated before the underlying type is complete.

So in the end I decided to rename die_info::sibling to die_info::next.
This name is slightly worse but (1) IMO it isn't really all that bad,
nobody would have blinked if it was called 'next' in the initial
patch, and (2) with the change to iteration it is barely used.
