add IO-1.20; mess with t/lib/io_*.t in an attempt to

keep platform hacks that aren't in the 1.20 dist; add new files
to MANIFEST; hack Makefile.PL; result hasn't been tested
anywhere

+Mon 15 Sep 1997 <gbarr@pobox.com> Graham Barr
+
+	o New modules
+	  - IO::Dir
+	  - IO::Poll
+
+	o IO::Socket
+	  - Changed new to call autoflush on the new socket
+	  - IO::Socket::INET->new now accepts a single argument
+	  - IO::Socket::INET default to protocol 'tcp'
+	
+	o IO::File
+	  - Added doc for new_tmpfile
+	
+	o IO::Handle
+	  - Removed use of AutoLoader for constants, constants are
+	    now defined as constant XS subs
+	  - Added fsync, but will not be avaliable for use
+	    unless HAS_FSYNC is defined, perls configure does not define
+	    this yet.
+	  - Moved bootstrap of IO.xs to IO.pm. IO::Handle no longer
+	    contains an AUTOLOAD sub in it's ISA hier
+
+	o IO::Seekable
+	  - Remove clearerr, as it is defined in IO.xs
+
+	o IO.xs
+	  - Patched IO.xs with patch from Chip for setvbuf warning
+	  - Added XS sub "constant" for backwards compatability
+
+	o Misc
+	  - Fixed IO::Socket::configure, it was not passing $arg to domain
+	    specific package
+	  - Changed all $fh variables in IO::Handle to $io and all $fh
+	    variables in IO::Socket to $sock as Chip suggested
+	  - Fixed usage messages to be consistant
+
+*** Release 1.15
+
+Sun 19 Jan 1997 <bodg@tiuk.ti.com> Graham Barr
+
+	o Updated PODs for IO::Handle and IO::File
+	o Modified IO.xs so that DESTROY gets called on IO::File
+	  objects that were created with IO::File->new_tmpfile
+	o Modified the domain2pkg code in IO::Socket so that it
+	  does not use blessd refs
+	o Created a new package IO::Pipe::End so that pipe specific
+	  stuff can be moved out of IO::Handle.
+	o Added Ilya's OS/2 changes to Pipe.pm and io_pipe.t
+
+	o These changes happened somtime before the release of 1.15
+	  - added shutdown to IO::Socket
+	  - modified connect to not use alarm
+	  - modified accept and connect to use IO::Select
+
+*** Release 1.14
+
+Tue 24 Dec 1996 <bodg@tiuk.ti.com> Graham Barr
+
+	o Updated to patches in perl core dist.
+	o Added C<use strict> to all modules
+	o Modified t/io_sock.t, hopefully the race condition has gone
+	o Added close statements to reader/writer in IO::Pipe
+	o IO::Handle::syswrite was calling sysread, fixed :-)
+
+*** Release 1.12
+
+Thu 19 Sep 1996 <bodg@tiuk.ti.com> Graham Barr
+
+	o Modified IO.xs so that it will compile with pre perlio version
+	  of perl (ie pre perl5.003_02)
+	o Modified IO::Socket::send so not to pass 4 arguments to send
+	  if the socket is connected
+
+*** Release 1.10
+
+Mon 11 Sep 1996 <bodg@tiuk.ti.com> Graham Barr
+
+	o Fixed a bug in IO::Socket which caused DESTROY to be called
+	  on a partly initialised connection
+	o Changed IO.xs to use Perlio
+	o Modified usage message to report correct package
+	o Added IO::File::new changes from Chip, to allow PERM to be passed
+	o Added sysread and syswrite methods to IO::Handle
+	o Updated documentation
+	o Fixed a bug in IO::Select that caused a hang if the last handle
+	  was removed.
+	o Added count method to IO::Select
+	o Renamed and modified tests so that they can be copied into the
+	  perl distribution
+	o Added fcntl and ioctl methods to IO::Handle
+
+Thu 25 Jul 1996 <bodg@tiuk.ti.com> Graham Barr
+
+	o It is now not necessary to call the domain sub-classes of
+	  IO::Socket. when connect is called it notes the domain.
+	  Domain specific methods, which are normally non-critical, are
+	  called via this note-ing.
+	o Added methods to IO::Socket to retrieve the domain, type and
+	  protocol of a given socket
+
+Tue 23 Jul 1996 <bodg@tiuk.ti.com> Graham Barr
+
+	o IO::Socket::connect changed how we do timeouts, as it did not work
+
+	o IO::Handle::new_from_fd removed method call to _ref_fd, which was
+	  a leftover from FileHandle
+
+Fri 28 Jun 1996 <bodg@tiuk.ti.com> Graham Barr
+
+	o Modified IO::Socket::UNIX::configure to default to using a socket
+	  type of SOCK_STREAM if no type is specified.
