Update to version 9.16.

Changes:

9.16 Thu Dec 27 11:56:43 CET 2012
    - the "so much new stuff your eyes will pop out" release.
    - INCOMPATIBLE CHANGE: renamed urlLauncher resource to url-launcher.
    - fix processing of DEC private mode save sequences (patch by Patrick
      Hemmer).
    - perl extensions now have their own manpages, installed as urxvt-NAME(1),
      e.g. urxvt-background(1) - see urxvt-extensions(1) for a list.
    - fix disabling of cursor blink with the option-popup menu (based on a
      patch by Jan Larres).
    - the font height is not augmented anymore when lineSpace is non zero.
    - fix "new pagemap" vs. "delete pagemap" mismatch ([] \ 
vs. non-[]),
      as diagnosed by clang.
    - fix height mismatch between active and inactive cursor when
      lineSpace is non zero (patch by Stanislav Seletskiy).
    - make it compile with LOCAL_X_IS_UNIX again (reported by
      nickfailure@gmail.com).
    - completely redone background pixmap support - users can now
      specify arbitrary expressions (And programs) that calculate
      new terminal backgrounds. see the urxvt-background manpage
      for details.
    - xrender is now required for background pixmap support.
    - perl extensions can now provide commandline switches and resources
      which show up in -help etc.
    - iso14755 51 mode window now displays row and column.
    - implement a -visual switch and move that and -depth to frills, also
      warn when we can't get the requested visual.
    - new env variable: RXVT_PERL_LIB.
    - allocate all screen memory in one go and let the virtual memory
      subsystem sort it out. this simplifies code, improves access
      locality, saves a bit of ram and makes things a bit faster, too.
    - remove support for libafterimage.
    - update to CVS version of libev, for a whopping 11kb size decrease.
    - do not ship yet another copy of ecb.h, use the one in libev or
      libptytty instead.
    - selectively mark some methods as cache-hot/cache cold, which
      might speed up execution but definitely decreases codesize.
    - Fix regression that prevented the scrollbar trough color
      from being applied (reported by Derek B. Noonburg).
    - Fix the scrollbar size for rxvt style (patch by Mark Robinson).

pkgsrc changes:
workaround for broken webserver, which doesn't allow fetching without User-Agent.
