This makes the new typed serialization the default (the old
serialization is not used but the code has not been cleaned up yet).
Some things are no working in the new world:
Chunking - The compound list is not working correctly any more. The
Chunks method is having issues because it assumed things based on the
old implicit chunking.
Commit - uses a `Set(Commit)` which means that the parent commit is
embedded. We need to change that to be `Set(Ref(Commit))` so that the
parent commit is referenced instead.
The new serialization format use "t " as in typed. The rest of the
message is a JSON array describing the typed data. The type is
described by types.TypeRef

Issues #281, #304
This adds code for finding imported type packages and generating
code for them, but does not yet handle generating code that uses
those types.

Also, switch to using a ref.Ref when getting/setting the package
ref in a TypeRef. Using a types.Ref just led to lots of manual
boxing and unboxing every time I wanted to use the reference.

This patch mostly merges parse.Package and types.Package, though it
can't quite go all the way. A types.Package doesn't have 'using'
declarations, while the parsed representation of a .noms file needs to
have that information. Hence, the parse package is moved to the 'pkg'
package, and pkg.Parsed is introduced. This type embeds types.Package
and adds the necessary additional information.
To make inroads on handling imports, I enhanced ParsePackage() (now
called ParseNomDL()) to actually process the 'alias' and 'import'
statements in the input and go replace namespaced type names in the
package with refs of imported packages. For example, the TypeRef for
'Bar' generated in the following package
alias Foo = import "sha1-ffffffff"
struct Bar {
f: Foo.RockinStruct
}
will actually return types.Ref{sha1-ffffffff} when you call PackageRef()
on it.
In addition, I've added a function to the new 'pkg' package,
which allows the caller to get the dependencies of a type package
from a chunk store.
Fixes issue #353, towards issue #294
These were two representations of, essentially, the same information.
They were separate because they provided different APIs to similar
information, but the APIs became more similar once we started using
native types (as opposed to Noms types) for the various Make*TypeRef()
functions.
Unifying these is a big step to unifying parse.Package and types.Package,
which is pretty necessary for dealing with imported packages.
Fixes issue #338
We want to explore encoding type information about Noms data in
the Noms database. So, we need some way to describe types. This
takes the shortest path to making a Noms type called "TypeRef" that
is a peer of Set, Map et al and can describe all the types we currently
use.
