go/packages: disable network, improve debug logging

When the name= query constructs the temporary module, it may find things
that don't resolve. In at least some cases (#28518), allowing go list
to access the network results in not just bad performance but actual
failures. Default GOPROXY to "off" when doing queries on the temporary
module to try to address that.

Also, add some more debug logging, including various environment
variables, so that it's easier to reproduce failing commands.

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
