fix #1505

- fix possible deadlock of the executor thread
- fix racecondition during the job consumation
- remove switch_work in all classes `minethd`
- move `consume_work` into `globalStates`

ignore duplicated equal job from pools

Some pools or proxys are sending multiple times in row the same job to the miner.
This PR will extent the miner to trigger an socket error if job with the same `jobID` than the current active job is received.

Move motd evaluation before the possibil part where a job is ignored.
