goimports to use the package name as a local qualifier in an import.
For example, if findImports("pkg", "X") returns ("foo/bar",
rename=true), then goimports adds the import line:
import pkg "foo/bar"
to satisfy uses of pkg.X in the file.
This change doesn't add any implementations of rename=true, though one
is sketched in a TODO.

Because goimports also sorts stdlib-vs-external differently
(whereas gofmt just sorts string-wise), we need to put a blank
line between imports of different classes. This happened in
some cases, but not all.

Fast path for the common case. Avoids scanning GOPATH usually.
