* 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.
