In REVERT-GLOBAL-IO-REDIRECTION and related function, must be sure to
not signal errors. In this case SLYNK:*LOG-OUTPUT* must be used
instead of *STANDARD-OUT*, since the standard streams whose
redirection are about to be reverted might be in an unconsistent state
after, for instance, restarting an image.

* slynk-mrepl.lisp (open-dedicated-output-stream): Improve doc slightlyt.
(revert-global-io-redirection): Log to SLYNK:*LOG-OUTPUT*.

Some multithread implementations like Allegro don't see special
variables like *EMACS-CONNECTION* in new spawned threads.

If *USE-DEDICATED-OUTPUT-STREAM* is nil, this results in a grey stream
whose function fails when called from these threads. Otherwise the
dedicated output socket works OK.

This is **not** a concurrency issue, since that is handled by
SEND-TO-EMACS fine.

Test case for Allegro CL, which should work either in the main or
secondary REPLs.

   (setq slynk-mrepl:*use-dedicated-output-stream* nil)
   (mp:process-run-function "yo" (lambda ()
      (loop repeat 5 do (princ "Hello, world") (terpri) (sleep 1))))

* contrib/slynk-mrepl.lisp (make-mrepl-output-stream): Use
SLYNK:MAKE-THREAD-BINDINGS-AWARE-LAMBDA.
(:slynk-mrepl): Export *USE-DEDICATED-OUTPUT-STREAM*,
*DEDICATED-OUTPUT-STREAM-PORT*, and
*DEDICATED-OUTPUT-STREAM-BUFFERING*

* slynk/slynk.lisp (make-thread-bindings-aware-lambda): New function.
(:slynk-api): Export MAKE-THREAD-BINDINGS-AWARE-LAMBDA.

* slynk-mrepl.lisp (open-dedicated-output-stream): On
implementations not supporting :LINE as a value of
*USE-DEDICATED-OUTPUT-STREAM*, use an additional grey stream.

(sly-dispatch-event): Pass :RAISE to `sly--open-inspector'.

* sly-stickers.el (sly-stickers-fetch): Always provide some
feedback when fetching stickers.

This is a tentative change for various reasons:

- In slynk/slynk-gray.lisp a similar technique to be use here (git
  8a91fe75 Nikodemus Siivola 2006-04-12 08:43:55 +0000 32) but was
  removed in 2008. Bringing it back seems harmless enough, but only in
  limited tests. Also STREAM-WRITE-STRING does not implement flushing
  on newline.

- Some Lisps completely ignore the BUFFERING arg to ACCEPT-CONNECTION.

- All this is trying to avoid a dedicated thread for flushing all the
  output streams, which, being a dirty hack, might in the end be a
  the most battle-tested alternative.

Also the default value for SWANK-MREPL:*USE-DEDICATED-OUTPUT-STREAM*
should probably be moved to a function that detects if connection is
between the same host or not. This is actually a separate problem,
but detected it while editing the manual.

* contrib/slynk-mrepl.lisp (*dedicated-output-stream-buffering*): Default
to :line, not t. SBCL and CMUCL seem to abide. CCL and ALLEGRO
ignore it.

* doc/sly.texi (REPL output control): New section.

* slynk/slynk-gray.lisp (stream-write-char): For the STREAM-WRITE-CHAR
interface, FINISH-OUTPUT when a newline is detected.

restructure the manual.
