Python 3 (#968)

Browse Source 
* Initial commit for Python3 branch that targets porting the following;
* Core manticore functionality
* x86/x64/arm architectures
* linux platform
* functioning unit tests for the above

* WIP ethereum support
notes:
* eth unit tests passing
* decree disabled
* ManticoreEVM.__init__ procs=1
* no iterpickle; see eth tests for setting stack size/recursion

* EVMAccount;
  add __hash__
  remove redefinition of __eq__

port/update EVM examples

* update stacksize / recursion limit

* pyevmasm dep updates, port linux examples

* update docs, tox/travis configs, port missing x86 unit test

* disable decree tests

* update example, update pyevmasm dep_links

* disable testArgumentsAssertions to speed up tests

* py35/36 json.loads compat fix

* fix summary output encoding

* disable eth binary test 808

* PEP479 - Python 3.7 support

* travisci; fix code coverage reporting

* port decree and tests

* codeclimate

* review changes;
	* cleanup
	* reset version
	* remove EVMAccount.__hash__, fix EVMWorld.get_balance()

* switch to official pyevmasm

* z3 version check - py3.5 fix

* pyevmasm; remove version requirement

* review changes;
	* remove redundant locking
	* shutdown executor manager on deletion

* review changes;
  * cleanup PY3FIX comments
  * _run_solc version ascii to utf encoding
