      Changed all macros which ignore the numeric arg to warn if there is one. · 7fd629f8

      Changed all macros to use %READER-ERROR as appropriate.
      Changed #+/- to work correctly under *READ-SUPPRESS*.  These macros actually do
      the same thing as usual under read-suppress.  However, we have to make sure
      that *read-suppress* is nil when reading the feature expression.  Also,
      consider feature expressions with package errors to be absent.
      Fixed various macros to return NIL rather than the value of *read-suppress*
      when *read-suppress* is true.
      Fixed #: to use the new READ-EXTENDED-TOKEN return value to detect colons,
      rather than just searching (since they might be escaped.)
      When *read-suppress* is true and *read-eval* is false, don't signal an error
      on #.  When we do error for #., use the correct READER-ERROR.
      Changed #r to just bind *read-base* and call read, instead of doing all sorts
      of weird stuff to reinvent numeric reading.  Check for illegal radices.
      Deleted some dead code once used for #=/##.
      Made # a non-terminating read macro character (the only one in standard CL.)
      So you can have symbols like foo#3, or whatever.

      Export new variable *ignore-extra-close-parentheses* if true (the default), · 7bc38abc

      extra close parens are only a warning, not an error.
      Export READER-ERROR, and change all reader code to signal this error as
      appropriate (or in some cases END-OF-FILE.)
      If a package is undefined, or an external symbol is missing, then signal
      READER-PACKAGE-ERROR (a subtype of READER-ERROR.)  This allows #+ to suppress
      this error on features without suppressing all read errors.  Changed these
      errors to only be signalled after the whole token has been gobbled, so that
      unwinding out of the handler won't leave the rest of the symbol unread.
      Improved readtable documentation.
      Fixed a number of problems with #=/##.  ## now works correctly with #S
      structures, and also detects some new error conditions (such as multiply
      defined labels.)  Also, we now bind the specials that control ## interaction so
      that if someone happens to read some other stream inside a read macro, things
      will still work.
      Added Ted's changes to make INTERNAL-READ-EXTENDED-TOKEN work when there are
      `|' escapes.  The main significance of this is that #+nil '|foo;bar| and
      #:|foobar| now work properly.  Also change this function to recognize unquoted
      colons so that #:foo:bar will error, but not #:foo\:bar.  Changed to not
      gratuitously upcase the input, and for READ-EXTENDED-TOKEN to call
      CASIFY-READ-BUFFER so that when READTABLE-CASE is :PRESERVE, you can #:Foo,
