Add pub (and by extension YAML) to the SDK.

Add pub (and by extension YAML) to the SDK.

Adds pub (under util) and YAML (which pub needs, under lib) to the SDK. Also
includes a shell script under bin for running pub.

It seems like we have more components now that need both a .bat file and a shell
script in bin/. Should we have one shared way of generating those?

I think yaml should be a subdirectory under util/pub . (and yaml should be a
subdirectory of pub in the repo, as well).

It seemed consistent to me to put it next to JSON, UTF, and URI which are also
general-purpose libs for parsing publicly-specced formats. Is there a reason
you'd want to limit YAML to pub?

This is a good idea. We probably should but I don't know enough about Windows
batch files to do it. (The one here is more or less blindly copied from frog.)

This will be LGTM once yaml is moved inside pub.

I don't think this is a commonly-desired library for dart developers. If I'm
wrong, we can move it to lib later. For the time being, though, I think it
should be within pub.

I don't understand why we wouldn't put a general-purpose library in the lib
directory. YAML is a reasonably widely-used language. The presence of an
easily-available parser may also help the dart community standardize on it for a
configuration format.
