ncurses 6.1 - patch 20180224

+ modify _nc_resolve_uses2() to detect incompatible types when merging
  a "use=" clause of extended capabilities.  The problem was seen in a
  defective terminfo integrated from simpleterm sources in 20171111,
  compounded by repair in 20180121.
+ correct Ss/Ms interchange in st-0.7 entry (tmux #1264) -TD
+ fix remaining flash capabilities with trailing mandatory delays -TD
+ correct cut/paste in NEWS (report by Sven Joachim).
