* Add construction and assignment from a generic contiguous container. Both compile-time and run time safety checks are made to ensure the safety of this conversion. * Remove base_uint::copyFrom. The generic copy assignment operator now does this functionality with enhanced safety and better syntax. * Remove construction from and dedendence on Blob. The generic constructor and assignment now handle this functionality. * Fix client code to adhere to this new API. * Removed the use of fromVoid in PeerImp.cpp as it was an inappropriate use of this dangerous API. The generic container constructors do it with enhanced safety and better syntax. * Rename data member pn to data_ and make it private. * Remove constraint from hash_append * Remove array_type alias
