Merge changes from unicode-string-buffer-impl-branch which gives
faster reads on external-formats.  This is done by adding an
additional buffer to streams so we can convert the entire in-buffer
into characters all at once.

To build this change, you need to do a cross-compile using
boot-2009-10-1-cross.lisp.  Using that build, do a normal build with
these sources.

For a non-unicode build use boot-2009-10-01.lisp with a 20a
non-unicode build.

o Add another slot to the extfmts for copying the state.
o Modify EF-OCTETS-TO-STRING and OCTETS-TO-STRING to support the
  necesssary changes for fast formats.  This is incompatible with the
  previous version because the string is not grown if needed.

o Set *enable-stream-buffer-p* to T so we have fast streams.

o Add new slots to support fast strams.
o In SET-ROUTINES, initialize the new slots appropriately.
o Update UNREAD-CHAR to be able to back up in the string buffer to
o Add implementation to copy the state of an external format.

o Change %SET-FD-STREAM-EXTERNAL-FORMAT to be able to change formats
  even if we've already converted the buffer with a different format.
  We reconvert the buffer with the old format until we reach the
  current character.  Then the remaining octets are converted using
  the new format and stored in the string buffer.
o Add FAST-READ-CHAR-STRING-REFILL to refill the string buffer, like
  FAST-READ-CHAR-REFILL does for the octet in-buffer.

o Add new slots to hold the string buffer, the current index, and
  length.  These are needed for the fast formats.

  FAST-READ-CHAR to support the string buffer.

o Microoptimization of SURROGATEP to reduce the number of branchs.

o Update with these changes

o These formats actually have state, so update them to take a handle
  an initial state.  These are needed if the string buffer ends with a
  leading surrogate and the next string buffer starts with a trailing
  surrogate.  The conversion needs to combine the surrogates together.

Add support for flushing out any state in an external format when
closing an output stream.  This causes things like

(with-open-file (s "foo" :direction :output :external-format :utf-8)
  (write-char #\u+d800 s))

to output the replacement character instead of creating an empty file.

o Add new slot to efx structure to hold the function to flush the
  state in an external format.
o Add accessor for the flush-state slot.
o Update DEFINE-EXTERNAL-FORMAT to allow specifying the flush
o Add macro to call the flush-state function.
o Added +EF-FLUSH+
o Use vm::defenum to name the constants instead of the hand-written
o Document the slots in an efx stucture.

o Add ef-flush def-ef-macro to flush the state of an external format
  when closing an output file.  If ef-flush-state is NIL, we just call
  EF-COUT to send out the replacement character.  Otherwise, the
  flush-state function is called to handle it.
o When closing an output character stream, call ef-flush to flush any
  state before flushing the buffers of the stream.
o Document the unicode slots in an fd-stream.

Fixes from Paul Foley:

o Standard streams no longer change formats when
  *default-external-format* changes.  Use
  stream:set-system-external-format instead, or (setf
o char-to-octets properly handles surrogate characters being written.
o Makes simple-streams work again.

This change needs to be cross-compiled.  2009-07 binaries work for
cross-compiling using the 19e/boot-2008-05-cross-unicode-*.lisp
cross-compile script.

o Move the +ss-ef-foo+ constants to here from strategy.lisp, and

o Update +ef-max+ accordingly.

o Use +ss-ef-str+ instead of +ef-str+ in simple-stream-strlen.

o Comment out +ss-ef-foo+ constants.
o Use +ef-max+ instead of +ss-ef-max+, which is no longer defined.
o Fix bugs in %dc-write-chars-fn:
  - Use ef variable
  - Need to call flush-out-buffer, not flush-buffer for dual-channel

Update from Paul:

I've moved some slots out of external-format so they can be shared
between external-formats that are identical in all but some variables.

Also fixed a bug in octets-to-string that made it return one character
short, and used char-code-limit instead of #x100 to determine when
octets-to-char returns a "?", so now it'll work without change on 8 or
16 bit lisps.

New external format stuff from Paul.

o Use this bootfile to compile the change in external-format
  structure.  Just needed to get rid of a restart when compiling pcl.

o Renames ENCODE-STRING to STRING-ENCODE.  Similarly for

o Updated for new external format.  I think the main change is not
  having to do a funcall for each character.

o New file describing different names for external formats.

o New file for composing external format for CR/LF

o New files supporting UTF-16 BE and LE formats.

o Copy over the new files and the aliases file too.

Update from Paul Foley.

o Disable package errors when loading up external formats.
o A minor patch allowing string-to-octets and vice versa to write into
  a preallocated array (though they might still allocate a bigger one
  if necessary),
o Fix up any confusion between simple-base-string and simple-string so
  that nothing breaks when/if they're not the same.
