Use of complete GList functionality? Change to GSList?

[Derek Atkins]

It turns out that there are few places where I can even send an engine
object wholesale.  So it turns out that in most cases I do have to
copy lists.  For example, I can send _most_ of the query terms without
modification.  However I do have modify the Account type, which means
I have to rebuild the whole Query Terms list-of-lists anyways.

Similary, Accounts, Transactions, and Splits are sufficiently
"different" that I wind up building my own lists as well.  Even kvp
frames must be rebuilt.

So, in the end, I do wind up copying, strdup'ing, etc. most data.

PS: Thanks for reminding me; I need to make sure I don't have a memory
leak in transmitting Queries.
