      Update from Paul Foley. · 989bf7e1
      rtoy authored
      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.

      Slight reimplemention of how tracing of local functions is done. We · 620750d0
      rtoy authored
      don't do the hackish list-of-name to find local debug function
      anymore.  This change allows us to retrace local functions when the
      function is redefined.
      
      code/debug-int.lisp:
      o Add :LOCAL-NAME keyword parameter to tell us to look for the local
        function within the given FUN.  The bizarre hack using a list as the
        FUN to do this is now gone.
      
      code/ntrace.lisp:
      o Change TRACE-FDEFINITION to return a fourth value if the function is
        a local function.  The fourth value is the name of the local
        function.
      
      o TRACE-1 recognizes the extra value from TRACE-FDEFINITION to
        determine if this is a local function that needs to be traced.
        Also, if DEFINITION is given, we process that carefully so we can
        trace the new definition with a local function.
      
      o UNTRACE-1 likewise updated to recognize and handle local functions.
      
      o TRACE-REFINED-UPDATE modified so that when a function is redefined,
        we retrace the function itself if it was traced (as before).  But we
        also look through the traced functions to see if we need to retrace
        the local definitions in this new function.

      o Use new RATIONAL-TO-DD function to convert bignums to · fa8ea7c8
      rtoy authored
        double-doubles.
      o Remove now unused DOUBLE-DOUBLE-FLOAT-FROM-BITS.
      
      This should fix an issue with converting bignums to double-doubles.
      For example (- (ash 1 150) 1) can now be be represented accurately as
      a double-double.

      rtoy authored
        double-double-floats.  (From Richard Fateman.)
      o Use that in FLOAT-RATIO for convertnig ratios to
        double-double-floats.
      o Remove old double-double-float support from FLOAT-RATIO.
      o Split FLOAT-RATIO in two, one supporting single/double floats, and
        one for double-double-floats.
      
      With these changes, I think we now have print/read consistency for
      double-double-float numbers.

      if the user set a different value.  Fix this so the correct precision
      is restored.
      
      compiler/x86/parms.lisp:
      o Add new static-symbol *FPU-PRECISION* to hold the precision bits
        that are given in (setf floating-point-modes).
      
      compiler/x86/float.lisp:
      o Whenever (setf floating-point-modes) is called, save the precision
        bits to *FPU-PRECISION* so that get restored correctly in
        DEALLOC-NUMBER-STACK-SPACE.
      
      compiler/x86/c-call.lisp:
      o Update DEALLOC-NUMBER-STACK-SPACE VOP so that when float-accuracy
        policy says so, we restore the precision from *fpu-precision*,
        instead of always making it :53-bit.
      
      code/lispinit.lisp:
      o Initialize the default precision to :53-bit on startup.

      Fix for Trac ticket #1. · 686a18ac
      rtoy authored
      Instead of having scale-exponent scale the number and using the scaled
      number for printing, have flonum-to-string scale the number for us.
      There is no loss in precision in flonum-to-string, so we don't have
      round-off errors in printing the number.  This means (format nil "~E"
      1.234567890123456789d4) is printed as "1.2345678901234567d+4" instead
      of "1.2345678901234565d+0".  Then prin1 and ~E both call
      flonum-to-digits with exactly the same number, so prin1 and ~E should
      have the same printed result.
      
      These tests pass:

      MAPHASH needs to grab the kv-vector from the hash table for each
      iteration because the hash table may have been rehashed.  (This mostly
      reverts the code to the previous version, where this bug was
      introduced.)

      retracing flet/labels functions.  This was caused by the hash-table in
