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.

fix possible race condition in jpsock

Fix condition on stellite check

Trigger event with a new job after the current pool job is updated.

set correct `iPoolId` for miner_work

Add masari coin 

- initialize miner_work iPoolId in the default constructor with the invalid pool id
- move definition of `pool_data` into an own file

Spell check

support stellite v4 fork

solve #1494

- add algorithm `cryptonight_v7_stellite` (internal named: `cryptonight_stellite`)

fix that cli option `--noAMDCache`

Small typo correction

fix wrong unique_lock usage

Use EXECUTABLE_OUTPUT_PATH and LIBRARY_OUTPUT_PATH

clang warns about the wrong usage:
