cmd/go/internal/vgo: speed up go.mod parsing

CL 106799 changed the mod file parser to be call
the fixer function for every module, version pair,
not just the ones with non-canonical semantic versions.
Of course, we don't want to hit the network for every line
of every go.mod, when most of them are fine.
Skip the network for the ones that are syntactically OK,
including proper matching between the module path and
major version.

For golang/go#24369.

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.
