STAT-153(GH-682): Remove signed_transaction from transaction_object so it can be stored in shared memory

by --block-interval-seconds chain_plugin command line option. #733

Authenticates producers using producer keys, optionally authenticates
non-producing peers using configured keys, and further optionally
allows unauthenticated connections.  Includes launcher support.

Also fix bug when a 100% producer node started up after a long (>64
second) delay and thought it's a 0% node.

Add additional information for debugging Travis builds.

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

Changed to report different exception for each type of rate limiting.  Fixed name for authorization account parameters.

Added db data members and logic for rate limiting code accounts and refactored rate limiting parameters into a rate limiting config object.

- update eoscpp
- update skeleton contract
- update cmake to install eoscpp, eoslib, and skeleton
- remove print statements

fix issues with missing construtors that strangely does not break locally even though it really should.  ref EOSIO/eos#175

exposed many bugs in the contract code and producer
fixed what I found

ref EOSIO/eos#175

add test for recursive inline messages, and add soft-concensus limits for recursion and total TX time

ref EOSIO/eos#175

first swipe at processing thereof, need tests badly

ref EOSIO/eos#175

update max block size, fix performance of chain_controller::head_block_producer, and increase batch sizes for benchmark

Log: Block number, timestamp, producer, duration to apply, transaction count, pending transaction count

- added checks on redundant scope specification in readscope #70
