807496a146 core: load pages if not loaded 
Since pages are now tracked with a single centralized structure, it is
possible for a page to have been unloaded a be kept in memory for
metadata purposes like going back in the stack.

Using the example of going to a parent page which was unloaded for
whatever reason: in this case we need to check if it's loaded, if not,
we load it. Locked still means the same thing, loaded just means the
contents of a page are present in memory and if they are present, they
must be in cache.

cd2b61d838 btree: cursor with lineal stack structure 
Removed MemPage from the code in favor of an array to encode the stack
of the cursor. This is both simpler and better in terms of memory
access.

e5836df160 write state machine 
Returning on ongoing IO requires to save the current state, therefore a
state machine makes sense for write operations. This information is
encoded in WriteInfo/WriteState.

fc71f2b32f traverse index properly 
interior index cells have values that are not in the leaves, e.g.

     (interior: 3)
    /            \
(leaf: 2)     (leaf: 4)

so their values need to be emitted after the left subtree is emitted.
