tree-walk.c: break circular dependency with unpack-trees
The unpack-trees API depends on the tree-walk API. But we've recently
introduced a dependency in tree-walk.c on MAX_UNPACK_TREES, which
doesn't otherwise care about unpack-trees at all.
Let's break that dependency by reversing the constants: we'll introduce
a new MAX_TRAVERSE_TREES which belongs to the tree-walk API. And then we
can define MAX_UNPACK_TREES in terms of that (since unpack-trees cannot
possibly work with more trees than it can traverse at once via
tree-walk).
The value for both will remain at 8. This is somewhat arbitrary and
probably more than is necessary, per ca885a4fe6 (read-tree() and
unpack_trees(): use consistent limit, 2008-03-13), but there's not
really any pressing need to reduce it.
