Summary:
We're experiencing cases where users are pulling down far more trees
than they need. Let's enable the ability to download a certain depth of trees.
In this diff we just implement the actual iteration limiting in native code. In
a future diff we'll make the appropriate python changes and add a test.

in the tree manifest.

They're actively fighting against the clang-format config

Summary:
In a future diff we'll be adding the ability to iterate over just a
subsection of a tree. In order for the resulting paths to be correct, we need to
be able to prime the start path. To do so, let's add a path argument to the
SubTreeIterator, and set it to empty string everywhere it's currently used.

Summary:
Now that markPermanent no longer requires a ManifestEntry to update the
node, the resultEntry field on all the iterators is unused. Let's delete it.

Summary:
Now that the node field is accessed via a getter that can lazily
compute it, let's get rid of the logic that proactively sets it. This will make
it easier to refactor the subtree iterator in a later diff.

Summary:
Previously the ManifestEntry node field was public and consumers could
read it directly. This required that the node field be updated manually, which
added complications to other code paths. In a future diff we'll be simplifying
the SubTreeIterator code to not require setting node, and to do so we make node
calculated in this accessor.

Summary:
This switches the treemanifest native iterators to use the ManifestPtr
class instead of Manifest*. ManifestPtr does ref counting, and in a future diff
we'll use this ability to have the subtree iterator iterate over a portion of a
larger tree so we can serve just parts of trees to gettreepack requests.

Summary:
The memcmp contract is that the result is >0, 0, or <0. If <0 it's not
guaranteed to be -1, so let's broaden the check a bit.

Summary:
The changes in this diff changes string comparisons using the compare method to
using equality operators.
Motivation:
- readability, simplifies code
- compare method is intended for sorting functions

Summary:
This assert appears to have always been wrong, but only respected when
built by clang. The SubtreeIterator class is created with an empty string in the
path member, and the only entry to the class is the next function which
immediately asserts that path is not empty. Since the only place path is set is
later in the function, there's no way it could start off as anything other than
empty.
