Import a stock copy of ncurses 5.8 into the vendor space.vendor/ncurses/5.8-20110226

It seems both local changes we made to 5.7 have already been fixed
upstream properly, so there is no need to preserve the changes. Also,
with SVN we import full source trees. Unlike CVS, where we removed
unneeded cruft.
