16be1a0bad rust: Rework treefile to be an object
In a later patch I'm going to add more API; basically rather
than doing the JSON parsing from C, we can add APIs to directly
access the treefile object.  This also demonstrates how we
can do more extensive APIs, in particular implement an "object"
in Rust.

The ownership across the FFI boundary becomes nicer here too,
we don't need to do a dance with the fd.

For writing this I found
http://jakegoulding.com/rust-ffi-omnibus/objects/
quite useful, as well as
https://github.com/rust-lang/regex/blob/master/regex-capi/src/rure.rs

e731f59007 rust: Split out treefile into its own module
Further prep for adding more code here.  The `lib.rs` then is the
collection of glue functions; perhaps in some ideal future it could
be generated even.

702daa2335 rust: Fix automake warnings, add unit tests to glibutils
Automake was warning about duplicate `clean-local` definitions, let's
do the nonrecursive automake dance.

And while I'm here, let's add some Rust unit tests that actually run
on `make check` too, since the whole unit testing bits of Rust are
awesome.

(I also tweaked the propagate bits to use the nicer `is_null()` method)

479406e6a5 Add support for YAML treefiles
Let's modernize and start supporting YAML treefiles. I'll dare make the
sweeping generalization that most people would prefer reading and
writing YAML over JSON.

This takes bits from coreos-assembler[1] that know how to serialize a
YAML file and spit it back out as a JSON and makes it into a shared lib
that we can link against. We could use this eventually for JSON inputs
as well to force a validation check before composing.

If we go this route, we could then turn on `--enable-rust` in FAHC for
now and drop the duplicate code in coreos-assembler.
