* Replace template <bool blockPassthrough>
by template <BlockPassthrough blockPassthrough> where BlockPassthrough is an
enum class.
This is mainly for better readability and for some type safety.
* Fixup some implicit conversions to bool
* Single server backup size in META and create.
* More size info in backup.
* Finish size and nrfiles for create and list.
* Add nrDBServers and potentiallyInconsistent to BackupMeta.
* Fix API documentation.
* Make Windows compiler happier.
* One more fix for Windows.
* Added creation date.
* Add Start/End subquery node skeleton
* Added a test query that triggers complex interna in the future and needs to proof that our work is side-effect free.
* Added first draft of ShadowRow Interface
* Refactored RegisterPlan and pulled it out of the ExecutionNode
* AqlItemBlock now has an additional hidden register to store subquery depth infromation. Right now no shadow rows are created, however thy could now make use of this situation
* Added API and test to insert new shadow rows into an OutputRow.
* Extrated test helper function
* Add template function to statically assert size of type
* Add Start/End subquery node skeleton
* Add Start/End subquery node creation to ExecutionNode
* Cleanup SubqueryEndNode
* Add test file
* Add isEqualTo to ExecutionNode
* Subquery nodes cleanup
* Update ExecutionNode tests
* Added API and tests to consume ShadowRows. Interface is there and compiles with templates, we might need to implement further underlying functions later on as we make progress on ShadowRows, it is only implemented in the minimal way (intentionally)
* Updates to testing code
* Added a test for nested ShadowRows and adapted OutputRow accordingly.
* More updates
* Add optimizer rule
* Fix optimizer rule
* Added additional memory include, seems to be required under GCC not udner CLANG
* it actually helps to save fies before commiting them...
* Fix optimizer rule (again)
* Fixed serialization/Deserialization of AqlItemBlock to contain the hidden subquery register now
* Added a c++ test for AqlItemBlock. It just covers the basics thus far and needs to be improved.
* Fixed toVPack of AqlInputRow for subqueries. Also added serialization / deserialization tests for AqlItemRow
* Added a c++ test for inputAqlItem row serialization => AqlItemBlock deserialization
* Add a public function to get plan from query
* Fix register planning
* Add test for splicing subquery nodes
* add static asserts for sizes of SubqueryStartNode and SubqueryEndNode
* Add comment about statically asserted size
* Fix isEqualTo virtual and override dance.
* Attempt to fix :windows: compile warning
* Fix isEqualTo, remove static_assert_size
* Remove a TODO; the plan owns the ExecutionNodes
* Only add stealPlan to Query when testing
* Remove another static_assert_size
* Fixed mac compile issues
* Added a serialization format to be backwards compatible to 3.5 whenever AQL item blocks need to be send over to remote nodes.
* Handle ShadowAqlItemRow in SingleRowFetcher
* Move some code from header to cpp
* Added more tests for serialization of shadow rows, and fixed a bug revealed by this
* Apply suggestions from code review
Thank you for review!

* Review comments. Thanks for spotting
* Fixed hidden merge conflicts
* Removed unused variable
* Added first test on ShadowRows in SingleRowFetcher. Found inconvenience in original code with it.
* Added a test for multi level shadow rows
* Added a test and fixed production for multiple consecutirve shadow rows.
* Added tests for pass through blocks and shadow rows
* Attempt to explain windows on how one can actually cast numbers into other number types...
* Add SubqueryEndExecutor
* Adapted RowFetcherHelper to be able to work on ShadowRows
* Fixed minor error in RowFetcherHelper that causes LIMIT tests to error
* Temporarily disabled test suites (sorry there is only one 'test case' in this suites that does all or nothing tests ...) as it tests a feature we cannot support in this intermediate state, we need to default disable our new rule first.
* IMplemented missing function to copy over SubqueryDepth between blocks
* Seperated assert, to see faster which part is violated
* Update arangod/Aql/AqlItemBlockSerializationFormat.h
