* First attempt to simulate thread waiting over information within the query
* Small fix to allow for isDirect handlers to go to sleep.
* Waiting in the necessary places now for the async request to be send.
* Thank you auto-casting compiler, you are totally right i absolutely wanted to use this bool value as an index in may Array. How could i possibly not want to use it here?

* Non-compiling intermediate commit for handover.
* Make branch compile again
* Started implementation of continueable rest cursor handler by moving the callbacks to the outer part. This is not yet fully tested!
* Made finalizeExecute noexcept. We cannot react to this errors as the response was potentially written before. Also introduced continueExecution in the RestHandler engine.
* First successful query wakeup.
* The wakeup callback now posts on the scheduler directly. A resthandler only needs to provide a callback that encapsulates the continueExecution call on this handler
* renamed finalizeExecute to shutdownExecute
* Added a differentiation between Handler and Callback in Query continuation. Handler will be posted in IO service. Callback will be executed directly
* fix audit log
* Removed callback from deleteQueryCursor. This cannot be waiting
* use CONDITION_LOCKER
* removed yet another thread-local variable
* Fixed forward declaration
* Made RestAqlHandler repeatable
* Use defer to close the query in RestAqlHandler. Now waiting will close the query as well.
* Added a mutex in the RestHandlers to make sure if the callback over network is too fast that there is only one Thread running in the RestHandler
* Captured the GeneralCommTask if it is posted to a RestHandler. This is necessary in the PAUSED case
* Refactoring of _noLockHeader responsibilities. Now the BaseHandler selects them and resets them after it is done. Only Coordinators are allowed to define them if a query is loaded.
* Removed reaction to existing nolockheaders in Coordinator Query Planning Phase
* Removed incorrect assertion.
* Further refactoring of NoLockHeaders. Now there is a wrapper class around it which allows for debugging and logging. The state now seems to be better. Also all non-rest-handler triggered queries clean up the NoLockHeaders properly.
* Fixed UserManager, now deletes nolock headers properly
* Swing to the Symphony of Destruction
* Forgot about community build...
* Fixed compiling of Catch tests
* Fixed community build
* need thread for size

* Fixed false query continuation
* Reset thread output to non-debug
* Added missing return statements
* Allow some CollectionMethods to hand-in a context that may contain a transaction. This is meant to honor nolock headers.
* Fixed hidden merge conflict
* Bugfix in aql-profiler.js: use plan.nodes order, not stats
* Added two profiler tests for filter
* Avoid too many getBlock calls in the FilterBlock
* Removed debug output
* RemoteBlock API will now send a done(bool) flag whenever we request documents from remote Servers. It is possible that we are DONE and have a result. The pre 3.4.0 API uses exhausted which is exclusive to a result. This API is still implemented for beckwards compatibility.
* Implemented an executeSync function in AqlQuery. This will block the thread until query execution is complete
* Added another test for FILTER, and one test for the HashedCollectBlock
* Added more tests for HashedCollectBlock; avoid unneccessary getSome calls
* Added an profiler IndexBlock test
* IndexBlock: avoid redundant getSome calls, added missing traceGetSomeEnd calls

* Removed debug log output
* Suppress clang warnings
* Bugfix: use of invalid stack pointer
* Bugfix: RemoteBlock::shutdown now sends code as int, not string
* Revert "Suppress clang warnings"
This reverts commit 05591649c59743c992edd5e78814edc8ca2a83e0.
* Bugfix: cleanup state in RemoteBlock ::shutdown, ::getSome and ::skipSome
