cmd/go/internal/modfetch: vgo.fetch becomes modfetch.Download

Refactoring so that all the cache directory management is in package modfetch.

While here, rename go.modverify to go.sum,
in preparation for forcing go.sum checking on
all the time.

Vgo will automatically move content from
go.modverify into go.sum when it sees it.

For golang/go#25525.

Versioned Go Prototype (vgo)

This repository holds a prototype of what the go command might look like with integrated support for package versioning.

See research.swtch.com/vgo for documents about the design.

Download/Install

Use go get -u golang.org/x/vgo.

You can also manually git clone the repository to $GOPATH/src/golang.org/x/vgo.

Report Issues / Send Patches

See CONTRIBUTING.md.

This is still a very early prototype. You are likely to run into bugs. Please file bugs in the main Go issue tracker, golang.org/issue, and put the prefix x/vgo: in the issue title.

Thank you.
