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.
