        * ext/dl/function.c: DL::Function now uses libffi

        * ext/dl/cfunc.c (rb_dl_set_last_error): set to non static so errors
          can be exposed.

        * ext/dl/closure.c: DL::Closure will now be used in place of
          ext/dl/callback/*.

        * ext/dl/dl.c: legacy callbacks removed in favor of libffi

        * ext/dl/dl_converions.(c,h): used for converting ruby types to FFI
          types.

        * ext/dl/callback/*: replaced by libffi callbacks.

        * ext/dl/lib/dl/callback.rb: Converting internal callbacks to use
          DL::Closure

        * ext/dl/lib/dl/closure.rb: Ruby parts of the new DL::Closure object

        * ext/dl/lib/dl/import.rb: More conversion to use DL::Closure object

        * ext/dl/lib/dl/value.rb (ruby2ffi): adding private method for
          DL::CPtr to ffi value conversion.
