Let untarring (and hence package installation) go faster (Bug#35909)
* lisp/subr.el (progress-reporter-update)
(progress-reporter-force-update, progress-reporter-do-update): Accept
new optional argument, SUFFIX.
* doc/lispref/display.texi (Progress): Document it.
* etc/NEWS: Announce it.
* lisp/tar-mode.el (tar-untar-buffer): Use a progress reporter instead
of calling message. Suppress message from write-region. Let-bind
write-region-inhibit-fsync to t.
