Summary:
The old code kept a PythonObj around inside the ManifestFetcher for fetching
manifest contents from the store. As part of moving the treemanifest code to use
the new native cstore API let's make the manifest code depend on a Store
abstraction and have one implementation be a PythonStore.
This removes almost all of the python dependencies from the core treemanifest
code, except some logic around running the python matcher during iteration and
writing directly to the python result dict during diff. We'll abstract those
away later.

Summary:
To begin the process of weaning treemanifest off of Python and on to the new
cstore, let's introduce a base Store class that implements a simple get()
function. UnionDatapackStore already implements this. Future patches will make a
Python version that implements this interface as well, so we can swap between
them easily.

Summary:
This implements the get function of UnionDatapackStore which iterates over
deltas and produces a full text. Unfortunately the delta chains currently come
out in reverse order (full text last), so we have to read all of them before we
can produce the delta.
Since mpatch takes a char*, and we want to avoid copying the array into a string
array for every read, we event a ref counted string reference type which let's
us transfer ownership of the char* to the caller.
Test Plan: Added a test

Summary:
A future patch will add C++ logic that applies delta's to get full texts, so we

it's dependencies.

Summary:
Implements the getdeltachain function on the new UnionDatapackStore class.
This required some modifications to the DeltaChainIterator. Since the results of
the iterator may cross multiple different chains, we need to keep each chain
alive until the iterator is destructed, so we need to keep a reference to each
chain. We also had to remove the size() property from the iterator since the
fact that the chain spans chains means we don't know the size up front.

Summary:
The remaining python parts of the store are a perf bottleneck when accessing
hundreds of thousands of pack file entries (like in treemanifest). Let's
implement them in C++.
This first patch just add the basic boiler plate, and implements a single
function getdeltachain(), with a test. Future patches will add more
functionality and other parts of the store.
Since cstore depends on cdatapack and ctreemanifest (the pythonutils.h part for
now), we need to tweak our setup.py to enforce a certain build order too.

let's move the treemanifest (including the python extension) into py-cstore.
Test Plan:
Built and ran the tests. Verified there was no ctreemanifest.so
dependency in the built cstore.so by using 'ldd cstore.so' on Linux and 'otools
-L cstore.so' on OSX.

Summary:
As part of unifying our storage layer into a single library, let's move
py-cdatapack into the new cstore directory. Future patches will move
ctreemanifest and the upcoming datapackstore into here as well.
py-cdatapack.h required some reordering since it seems forward declarations work
a little differently between C and C++. There were no code changes though,
except one int->size_t fix.
