internal/gopathwalk: create

Extract goimports' logic for walking Go source directories into a
separate package, suitable for use in go/packages. No functional
changes. Added a convenience feature to fastwalk, allowing the user to
say that they're done with a directory and stop receiving callbacks for
it.

Testing is a little light; I expect goimports' tests to cover most
everything we care about.

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.
