cruft needed to compile ntfs support into imagezip, including the i18n
unicode library
routines from FBSD 5.0.  Most of the magic is in the makefiles, but there
is a patch for the ntfsprogs package we're using to get NTFS support.
(patch contributed by Russ).

Note that the ntfsprogs tarball is located in emulab webspace (like TG).

Don't worry!  You still have to pass --enable-windows to configure in order to
pull any of this in, although it should compile nicely from here on out.

Russ will commit his imagezip changes (hiber, and page file skipping) soon.
