  Modified files:
    include              printf.h 
    lib/libc/stdio       Makefile.inc xprintf.c xprintf_vis.c 
  Added files:
    lib/libc/stdio       xprintf_errno.c xprintf_quote.c 
  Log:
  Make the %V{is} extension handle a NULL pointer like %s does: output "(null)"
  
  Add %M{essage} extension which prints an errno value as the
  corresponding string if possible or numerically otherwise.
  
  It is not currently possible to do the syslog(3) like %m extension
  because errno would need to get capatured on entry to the first
  function in the printf family, so %M requires you to supply errno
  as an argument.
  
  Add %Q{uote} extension which will print a string in double quotes with
  appropriate back-slash escapes (only) if necessary.
