cmd/go/internal/modfetch: update for new gitrepo backend

Drop API-based access to Bitbucket, Gerrit, GitHub,
now that we can (again) talk directly to their Git repos.

Also drop general LatestAt query in favor of plain Latest
(at current time on default branch), which is all that we
needed and all that makes sense when talking directly
to Git servers.

For golang/go#24915 (still need hg, svn, bzr, fossil).
Fixes golang/go#23955 (no GitHub API calls, so no rate limits).
Fixes golang/go#24085 (no GitHub API calls, so no 403 responses).
Fixes golang/go#24076 (GitHub enterprise's go-get=1 pages are now OK).
Fixes golang/go#24102 (no more canonical GitHub import path checks).

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.
