* ci: revert docs job checking for nightly tag

* ci: exclude docs job from nightly builds in gitlab script

* fix (light/provider) : Make `read_only executions` read-only (#9591)

* `ExecutionsRequest` from light-clients as read-only

This changes so all `ExecutionRequests` from light-clients are executed
as read-only which the `virtual``flag == true ensures.

This boost up the current transaction to always succeed

Note, this only affects `eth_estimateGas` and `eth_call` AFAIK.

* grumbles(revert renaming) : TransactionProof

* grumbles(trace) : remove incorrect trace

* grumbles(state/prove_tx) : explicit `virt`

Remove the boolean flag to determine that a `state::prove_transaction`
whether it should be executed in a virtual context or not.

Because of that also rename the function to
`state::prove_transction_virtual` to make more clear

* ethcore: fix detection of major import (#9552)

* sync: set state to idle after sync is completed

* sync: refactor sync reset

* parity: revert clib bump and fix tests

* Fix path to parity.h (#9274)

* Fix path to parity.h

* Fix other paths as well

* ethcore-io retries failed work steal (#9651)

* ethcore-io uses newer version of crossbeam && retries failed work steal

* ethcore-io non-mio service uses newer crossbeam
