Log Message:
Update mlterm to 3.2.0.

In this version, mlterm now supports NetBSD wsfb framebuffer
so NetBSD users can use a multi-lingual terminal without
Xserver on ports that support wsdisplay framebuffer console,
i.e. NetBSD/i386 with VESA framebuffer, NetBSD/dreamcast,
or even NetBSD/luna68k with 1bpp framebuffer.

Special thanks to Araki Ken, an auther of mlterm, for
various efforts and improvements for NetBSD wsfb support,
including dumb 1bpp optimizations on luna68k.
mlterm-fb demonstration movies are available on YouTube:

 http://youtu.be/BP8AIceWgxA  (NetBSD/luna68k 6.1)

pkgsrc changes:

 - update descriptions per the framebuffer support
 - add a MESSAGE file to mention miscellaneous configurations to use mlterm
 - remove MAKE_JOBS_SAFE=no which has been fixed in upstream Makefiles
 - split SUBST rules into ones for Makefiles, man page, and config files
 - install misc README files in doc dirs which are useful after installation
 - add "mlterm-fb" and "ibus" options and make mlterm-fb default
   on supported platforms
 - update PLIST per above changes (XXX tested only on NetBSD)
