Remove support for block cipher padding methods in engine. Like S2K,

they were not used at all outside of the core library implementations.

One change is that now get_bc_pad returns a new object, instead of a
pointer to a const shared padding method. This does imply a bit more
dynamic memory overhead, but the modes are pretty light (stateless, for
the most part), so this doesn't seem like a big deal. So modify ECB and
CBC classes to add destructors to delete the padding object.
