This deletes the raw and golist packatges, instead using the main
Package structure as the serialzied form between the build tool and the
loader.
This requires a few new fields on Package for information that we used
to hide, and some extra json tags on Package.
It also required Package to have custom JSON marshalling methods.

If GOROOT is unset (as is common now),
then the output of "go env GOROOT" may
differ from the GOROOT inferred by alternate
compilers being executed and also from the
value of runtime.GOROOT() inside compilebench,
used by go/build. Harmonize all of these by
setting GOROOT explicitly (will fix subcommands)
and by invoking the go command to learn about
packages instead of assuming go/build has any
idea what it's doing.

This implementation is incomplete. It will never support test packages
because of the two phase test loading process of the Loader. It
also doesn't reliably have access to export data so it will
always do an upgraded whole-program query. But we'll try to get
