Previously our logic for keeping track of when we're visiting the head
of a list was done via a global bool. This can be overwritten if dealing
with nested lists, so use stack entries to track this instead.

Currently we do 3 things wrong:
1) The list iterator, in practice, is used in a manner where the pointer
we pass in is the same as the pointer we assign the output to from
visit_next_list(). This causes an infinite loop where we keep freeing
the same structures.
2) We attempt to free list->value rather than list. visit_type_<type>
handles this. We should only be concerned with the containing list.
3) We free prematurely: iterator function will continue accessing values
we've already freed.
This patch should fix all of these issues. QmpOutputVisitor also suffers
from 1).

type's visitor function to free() any heap-allocated data types.
