stty: add support for extproc/LINEMODE
Add support for the "extproc" option which is well described at:
http://lists.gnu.org/archive/html/bug-readline/2011-01/msg00004.html
* src/stty.c (usage): Describe the extproc option if either the
Linux EXTPROC local option is defined, or the equivalent
BSD TIOCEXT ioctl is defined.
(main): Make the separate ioctl call for extproc on BSD.
* doc/coreutils.texi (stty invocation): Describe the option,
and reference the related RFC 1116.
* NEWS: Mention the new feature.
