Change to allow xrefs to be shown in the current window |

Hi! I added another possible value for xref-show-xrefs-function in
xref.el. In master, it can be set to value xref--show-xref-buffer,
which shows the result list from xref-find-references in another
window. The proposed, new value xref--show-xref-same-window shows the
result list in the current window. I added it because I prefer that
presentation over the other.
Would this patch be of interest to you?
Proposed Changelog entry:
* lisp/progmodes/xref.el: changed xref--show-xref-buffer and added
xref--show-xref and xref--show-xref-same-window.
I made the following diff from master, updated May 11 2018:

;; This part of the UI seems fairly uncontroversial: it reads the
;; identifier and deals with the single definition case.
;; (FIXME: do we really want this case to be handled like that in
;; "find references" and "find regexp searches"?)
;;
;; The controversial multiple definitions case is handed off to
;; xref-show-xrefs-function.
