Bug Fixes Updates

Pat is releasing minor changes in several packages to fix several problems reported by users in LQ or directly to him. Most of them fix performance issues.

hplip is rebuilt to make the hp-config_usb_printer process runs in the background to avoid long delays until it's started completely. vim and vim-gvim are downgraded to patch 1087 to give more time for upstream to fix the regression after the regexp engine was rewritten. libffi is rebuilt to relocate ffi include files back to /usr/include, and patched the pkgconfig file to point there as well.
