      everything is defined yet.  Hence, add dummy
      %SET-FD-STREAM-EXTERNAL-FORMAT and move the real one to
      fd-stream-extfmt.lisp.  This builds.
      
      code/fd-stream.lisp:
      o Always call %SET-FD-STREAM-EXTERNAL-FORMAT, even if
        LISP::*ENABLE-STREAM-BUFFER-P* is NIL.
      
      code/stream.lisp:
      o Move %SET-FD-STREAM-EXTERNAL-FORMAT to fd-stream-extfmt.lisp.
      o Add dummy implementation of %SET-FD-STREAM-EXTERNAL-FORMAT.
      
      code/fd-stream-extfmt.lisp:
      o %SET-FD-STREAM-EXTERNAL-FORMAT moved here.

      Merge changes from unicode-string-buffer-impl-branch which gives · 392d3e59
      rtoy authored
      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.
      
      code/extfmts.lisp:
      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.
      
      code/fd-stream-extfmt.lisp:
      o Set *enable-stream-buffer-p* to T so we have fast streams.
      
      code/fd-stream.lisp:
      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
        unread.
      o Add implementation to copy the state of an external format.
      
      code/stream.lisp:
      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.
      
      code/struct.lisp:
      o Add new slots to hold the string buffer, the current index, and
        length.  These are needed for the fast formats.
      
      code/sysmacs.lisp:
      o Update PREPARE-FOR-FAST-READ-CHAR, DONE-WITH-FAST-READ-CHAR, and
        FAST-READ-CHAR to support the string buffer.
      
      code/string.lisp:
      o Microoptimization of SURROGATEP to reduce the number of branchs.
      
      general-info/release-20b.txt:
      o Update with these changes
      
      pcl/simple-streams/external-formats/utf-16-be.lisp:
      pcl/simple-streams/external-formats/utf-16-le.lisp:
      pcl/simple-streams/external-formats/utf-16.lisp:
      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 · 1325c62e
      rtoy authored
      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.
      
      code/extfmts.lisp:
      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
        function.
      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
        values.
      o Export +REPLACEMENT-CHARACTER-CODE+
      o Document the slots in an efx stucture.
      
      code/fd-stream.lisp:
      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.
      
      code/exports.lisp:
      o Export +REPLACEMENT-CHARACTER-CODE+

      Fixes from Paul Foley: · 94ed0111
      rtoy authored
      o Standard streams no longer change formats when
        *default-external-format* changes.  Use
        stream:set-system-external-format instead, or (setf
        external-format).
      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.

      Change how the CMUCL extension enabling both character and binary I/O · 5795a2f7
      rtoy authored
      is done, based on a suggestion from Lynn Quam.
      
      o Add BINARY-TEXT-STREAM structure for streams that support binary and
        character I/O.  This is basically an FD-STREAM.
      o Export BINARY-TEXT-STREAM from the EXTENSIONS package.
      o OPEN will recognize :class 'ext:binary-text-stream to enable such
        streams.
      o Removed *FD-STREAM-ENABLE-CHARACTER-AND-BINARY-INPUT*, since we use
        OPEN to specify that now.
      
      Use boot-2005-03-2.lisp to bootstrap this change.

      Apply Lynn Quam's proposed enhancements to fd-streams allowing input · d4ad6755
      rtoy authored
      streams opened with element-type (unsigned-byte 8) to be also opened
      for character input.  This gives simple-streams semantics to
      fd-streams.
      
      * code/fd-stream.lisp
        o Make FD-STREAM-IN use PICK-INPUT-ROUTINE to select the correct
          type of input.
        o Add *FD-STREAM-ENABLE-CHARACTER-AND-BINARY-INPUT* to allow binary
          and character input.  Currently defaults to NIL, but will change
          to T.
      
      * code/stream.lisp
        o New READ-INTO-SIMPLE-STRING to allow stream element-type of
          (unsigned-byte 8).
        o Support reading and writing simple arrays of single-float and
          double-float.
        o Strings can be written to streams of element-type '(unsigned-byte
          8).
      
      * tools/worldcom.lisp
        o Compile stream-vector-io.lisp.
      
      * tools/worldload.lisp
        o Load stream-vector-io.
      
      * code/stream-vector-io.lisp
        o New file implementing READ-VECTOR and WRITE-VECTOR.

      o FILE-STRING-LENGTH can be used on BROADCAST-STREAM's where the
        result is 1.
      o Graphic characters are not printed using the character name (hence
        #\space is printed #\ )
      o Make INPUT-STREAM-P and OUTPUT-STREAM-P work correctly on synonym
        streams.
      o MAKE-STRING-INPUT-STREAM was not accepting NIL for the optional END
        argument.
      o Close string-input streams.  (We weren't before.)
