* issue 496.3: backport 3.4: move more coordinator-related logic out of TRI_vocbase_t, rename some arangosearch view configuration parameters, remove some consolidation policies, update iresearch to revision 6fd9760d81b136f769e277ea5b8f53996ed7a1ca
* address merge issue
* backport: remove code causing nullptr access
* invalidate payload for each field in FieldIterator before setting a value
* address compilation issues
when just starting the arangosh without a connection to a server
and running code such as `require("internal")`, the shell always
printed "connection class corrupted", which is somewhat misleading.
just don't print this error here, as it is useless
* Improve logging on coordinator when doing `arangorestore`.
* Return more error information in `mergeResults`.
* Longer timeout for communication coordinator -> leader for writes.
This is taking into account possible write stops from followers needed
to get in sync.
* Fix compilation.
* Get rid of numbers in exception log messages.
* Fix compilation.
* Fix indentation.
* Feature/arangosearch speedup removals (#7134)
* speedup document removals and optimize data model
* fix invalid constexpr
* reduce number of heap allocations for removals (#7157)
* open up connect limit to allow one DNS retry
* add CHANGELOG entry for dns retry fix
* update warning message wording
* Add lock line that was missed in recent scheduler merge
* backport: switch scope of responsibility between a TRI_vocbase_t and a LogicalView in respect to view creation/deletion
* backport: ensure arangosearch links get exported in the dump
* backport: ensure view is created during restore on the coordinator
* Updates for ArangoSearch DDL tests, IResearchView unregistration and known issues
* Add fix for internal issue 483
* Stop libcurl from trying to POST stdin
* Stop relocking every iteration in wait
* Remove unimplemented function
* Restrict setting of empty POSTFIELDS to POST requests
* Revert locking change
* Implement `syncCollectionCatchup` in DatabaseTailingSyncer.
First stab, might not even compile.
* Fixed a typo.
* Fix a typo and a compilation problem.
* Further compilation fix.
* Implement two stage catchup.
* Two small corrections.
* Unified error messages in Synchronize shard job.
* Improved a code comment.

* Renamed doHardLock => toSoftLockOnly and inverted default value
* Merged soft/hard foot logic with Transaction splits
* Use scopeguards to cancel readlocks
* Removed incorrect skipping of Batches in RocksDB Tailing syncer. This caused issues, whenever one transaction was spiltted.
* Added a test for Splitting a large transaction in RocksDB
* Reactivated skipping in RocksDB Wal Tailing (reverts initial fix)
* Actually include lastScannedTick in CollectionFinalize. Proper fix, kudos to @jsteemann.
