refactor/rename: make -from syntax support string literals for complex import paths.

(They may contain any character, after all.)

Also, allow but don't require parens and stars.
e.g. (*"encoding/json".Decoder).Decode or "encoding/json".Decoder.Decode
     but not encoding/json.Decoder.Decode.

Since -from queries are now Go expressions, we use the Go parser.
(Thanks to Rog Peppe for the suggestion.)
