(call-with-buffer-syntax): New functions.

description.

slime-buffer-connection and slime-current-thread when create a fresh
buffer.

spawn-worker-thread.

(wrap-sldb-vars): New function.  When evaluating a form in a frame,
Allegro uses the "old" dynamic context, i.e., dynamic variables like
*sldb-level* and the like are reset to the values in those frames.
But if *sldb-level* is reset to 0, Emacs doesn't notice when a
(recursive) error occurs while evaluating the form in the old frame.
wrap-sldb-vars saves the debugger related variables to avoid such
confusion.
(eval-string-in-frame, pprint-eval-string-in-frame): Use it.

with lexical variables in the frame.  Wrap an explicit LET around the
form to get the similar behavior as in the other Lisps.

(inspect-for-emacs (structure-object)): Remove structure related
methods.  It's already covered by the general case with
allegro-inspect.
(common-seperated-spec): Deleted

Removed a lot of really ugly reader-conditionalized code, much of it
for archaic lisps (#+cltl2, #+lcl3.0, #+mcl1.3.2, etc).

SBCL sometimes gives (NIL).

(source-path-stream-position): Use it.
