ncurses 5.9 - patch 20130216

+ modify test/testcurs.c to work with mouse for ncurses as it does for
  pdcurses.
+ modify test/knight.c to work with mouse for pdcurses as it does for
  ncurses.
+ modify internal recursion in wgetch() which handles cooked mode to
  check if the call to wgetnstr() returned an error.  This can happen
  when both nocbreak() and nodelay() are set, for instance (report by
  Nils Christopher Brause) (cf: 960418).
+ fixes for issues found by Coverity:
  + add a check for valid position in ClearToEOS()
  + fix in lib_twait.c when --enable-wgetch-events is used, pointer
    use after free.
  + improve a limit-check in make_hash.c
  + fix a memory leak in hashed_db.c
