ncurses 5.9 - patch 20130727

+ improve configure macros from ongoing work on cdk, dialog, xterm:
  + CF_ADD_LIB_AFTER - fix a problem with -Wl options
  + CF_RPATH_HACK - add missing result-message
  + CF_SHARED_OPTS - modify to use $rel_builddir in cygwin and mingw
    dll symbols (which can be overridden) rather than explicit "../".
  + CF_SHARED_OPTS - modify NetBSD and DragonFly symbols to use ${CC}
    rather than ${LD} to improve rpath support.
  + CF_SHARED_OPTS - add a symbol to denote the temporary files that
    are created by the macro, to simplify clean-rules.
  + CF_X_ATHENA - trim extra libraries to work with -Wl,--as-needed
+ fix a regression in hashed-database support for NetBSD, which uses
  the key-size differently from other implementations (cf: 20121229).
