Make read-char and read-byte signal errors when given the wrong kind
of streams.  This is a change from current 20a and 20b behavior which
didn't signal errors, but matches the behavior for releases 19f and

But allow them to work on binary-text-streams.  This is the same
behavior as before for binary-text-stream streams.

However, read-sequence no longer allows reading from streams into
arbitrary objects, unless the stream is a binary-text-stream stream.

  fd-stream-in/fd-stream-out if we have a character or
  binary-text-stream stream.
o Don't update the fd-stream-string-buffer or lisp-stream-in-buffer if
  we have a binary-text-stream because that will mess up how
  fast-read-char and fast-read-byte dispatch to do the right thing for
  binary-text-stream streams.

o Set the fd-stream-in and fd-stream-bin slots appropriately depending
  on whether we have a character, binary, or binary-text-stream
o Only create the lisp-stream-in-buffer if we do NOT have a
  binary-text-stream.  (Binary streams didn't use the
  lisp-stream-buffer previously, so no change there.  Character
  streams use the lisp-stream-buffer and/or lisp-string-buffer.)
o Set the fd-stream-flags appropriately for the kind of stream this
  is.  Checking a fixnum is faster than checking the type of a stream.

o Add FLAGS slot to LISP-STREAM so we can tell what kind of stream
  (character, binary, binary-text-stream) we have.

o Change FAST-READ-CHAR so that if we have a have a binary or
  binary-text-stream stream, we dispatch to the fast-read-char methods
  to do the right thing, including signaling an error for the wrong
  kind of stream.
o Change FAST-READ-BYTE so that if we do not have a binary stream, we
  dispatch to the fast-read-char method to do the right thing.

o With the above changes, we can no longer write characters to a
  binary stream, like a FASL file.  Make the fasl file a
  binary-text-stream so that we can.  (Alternatively, we could create
  the FASL header as a string, convert to octets and dump the octest
  to the file.  This is easier, and should still be fast for writing

Clean up how (setf stream-external-format) works.  This change
requires a cross-compile using the default cross-compile script.

o Remove the SAVED-OC-STATE slot from an FD-STREAM because we don't
  need it anymore since we have the OCTET-COUNT slot.

o Don't need to copy the current OC-STATE to SAVED-OC-STATE.  Remove
  code and update comments.

o Use the OCTET-COUNT slot to figure out how many octets have been
  consumed so far to produce the characters that have already been
  read.  Don't need to do the re-conversion anymore, so we don't need
  the SAVED-OC-STATE anymore.
o Add support for the case where we were using the ISO8859-1 external
  format and are now switching to another external format that
  requires the string-buffer.

Fix a couple of issues with changing the stream external format in

o When changing the external format, the new converted characters need
  to go into the string-buffer at the point after the last character
  was read.  This maintains consistency if the format is changed
  again before we have to read in another buffer of octets.
o Handle the case where an external format that uses the string-buffer
  is changed to ISO8859-1, which doesn't.  In this case, the converted
  characters need to be copied to the in-buffer in the right place and
  the string-buffer needs to be set to NIL to indicate that the
  string-buffer is not used anymore.
o Add a note that we don't handle the case of changing ISO8859-1 to
  another external-format that uses a string-buffer.

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.

Implement fast external formats.  This is done for buffered streams
where an in-buffer would be allocated.  For character streams, a
string-buffer is also allocated.  Whenever the string-buffer is empty,
the in-buffer is filled with new octets, and the octets are
immediately converted to a string.  FAST-READ-CHAR pulls the
characters from string-buffer as needed.  This speeds up utf8
processing by 30-40% (for read-line).

o Precompile the +ef-os+ slot for iso8859-1. (Not necessary?)
o Set *enable-stream-buffer-p* to T to enable the buffer.

o In SET-ROUTINES, allocate the string-buffer when appropriate.
o Update FD-STREAM-MISC-ROUTINE to handle :unread with the string

o Update UNREAD-CHAR to handle the string buffer.  May need more
o Add FAST-READ-CHAR-STRING-REFILL to refill the in-buffer and

o char-to-octets properly handles surrogate characters being written.

o Fixed bug with shared code between formats
o Built a cache into the ef-macro functions so it doesn't need to call
  find-external-format so often at runtime

o Use the changes in code/extfmts

o Removed all the commented-out code in fd-stream which is duplicated
  in fd-stream-extfmt.

More updates from Paul.  fd-stream-extfmt.lisp actually implements the
external formats which now work.

Cross-compile works fine.

o New file implementing external formats

o Compile extfmts.lisp before fd-stream, since fd-stream uses some
  macros from extfmts.
o Compile fd-stream-extfmt

o Load fd-stream-extfmt at the end.  (Can't load it as part of
  kernel.core.  Not enough is set up yet.)

o Avoid loading files, etc., early in the boot sequence
o Add INVERT-TABLE function needed by some formats.

o Some cleanups (I think)
o Fix EOF handling
