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.

+  tclock - analog/digital clock for curses.
+  If it gives you joy, then
+  (a) I'm glad
+  (b) you need to get out more :-)

+  This program is copyright Howard Jones, September 1994
+  (ha.jones@ic.ac.uk). It may be freely distributed as
+  long as this copyright message remains intact, and any
+  modifications are clearly marked as such. [In fact, if
+  you modify it, I wouldn't mind the modifications back,
+  especially if they add any nice features. A good one
+  would be a precalc table for the 60 hand positions, so
+  that the floating point stuff can be ditched. As I said,
+  it was a 20 hackup minute job.]
