cmd/go/internal/modcmd: add "vgo mod" command

The new "vgo mod" command in this CL provides a single command
for a handful of basic module maintenance and query operations,
instead of allowing them to explode the number of non-package-based
go subcommands.

In a followup CL, "vgo vendor" will become "vgo mod -vendor", and
"vgo verify" will become "vgo mod -verify".

In another followup CL, "vgo sync" will remove unused modules from go.mod.

See the help text in modcmd/mod.go for an overview of the command.

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.
