This reverts commit 3b5e03df.

Removed action::current_action_data and PACKED macro since all actions are packed/unpacked according to the abi definition and cleanup of tests. GH #2350

implment stub of new eosio.msig contract using new contract structure
define eosio.msig abi
eoslib name class now uses {} rather than constructor and uses magic_get
serialization

Add missing tests

issue #1754

- fix bootseq tests
- related to #1614 and #1752
- new dispatch_inline helper
- define producer_schedule_type
- implement eosio.token as a independent contract in new contract style

Rename action_size to action_data_size.

rename eos_assert to eosio_assert, implement is_account() api, and move implementation from apply_context.hpp to .cpp

added tests for the WASM currency contract and fixed issues it exposed, refactored contract initialization as a require_recipient where the logic of init vs apply is now in the wasm_interface

Added test for basic wasm contract loading/unloading.  Fixed bugs in the intrinsic code and made it impossible to complile with the same class of bugs in the future.  Did some basic style/renaming in the contracts directory and in the enclosed tutorial/doxygen files

Also since the API changes creeped into so much code,
decided to just go ahead and change the remaining code. #624
