[bug-libunistring] libunistring-0.9.4 release candidate

[Daiki Ueno]

Hello,

As some of you might know, I'll be taking care of the library for now
(co-maintainers are welcome).  Before applying big changes such as
updating to the latest Unicode standard, I thought it would be a good
idea to make a new release from the current git master.

So, I've generated a pre-release tarball:
http://alpha.gnu.org/gnu/libunistring/libunistring-0.9.4-rc1.tar.gz

I applied a couple of minor build fixes, but if you find anything else
which should be included in the release, please report to the list.

Regards,
