refactor/rename: require cl-lib, use cl- namespace

go-rename.el used the cl list* macro without requiring cl. This only
worked for people who required it for other code. go-guru.el, before its
removal from the tree, changed from cl to cl-lib, indirectly breaking
go-rename.el for some users.

Switch to using cl-list* and require cl-lib.

Fixes golang/go#17468

cmd/guru: emacs: add go-guru-mark

This function allows marking a specific syntactic element. One possible
use is marking a function call to extract it into a variable.

go/buildutil, cmd/guru: extract overlay context into buildutil

This extracts the overlay context and archive parsing from guru into
buildutil.

At least one tool (gogetdoc) has a vendored copy of this code already,
and more tools implementing the same functionality will follow.

The new code in buildutil is an almost identical copy of the code in
guru (names aside), except for the following changes:

- Instead of reading into a bytes.Buffer, we read directly into a []byte
  of appropriate size

- sameFile first attempts a simple comparison of path.Clean'ed paths.

cmd/guru: emacs: add function for expandiong region

The go-guru-expand-region function uses the "what" query to determine
the enclosing regions. Consecutive calls to go-guru-expand-region will
reuse a cached version of the list.

all: address vet issues, fix print calls

This fixes some print calls with wrong format directives. Additionally,
struct initialisers were changed to use keyed fields, purely to reduce
the amount of noise generated by go vet.

present: dont crash if address searched backwards

For /start/,/end/, the /end/ address can wrap around and match somewhere
before /start/. Handle this case without crashing.

Fixes golang/go#7163.
