* reduce extractions to projections
* recycle string buffers in SocketTask
* micro optimizations for mmfiles indexes
* added special lookup function for _key
* moved function into the correct file
* speed up key buffer allocations a bit
* added noexcept specifier
* correctly name variable
* explicitly move bounds
* fix and speedup from/toPersistent functions

* cppcheck
* try to fix compile error on MacOS
* bug fix for MacOSX
* missing namespace (in Windows compile)
so that other features can indicate that they need a storage engine
but do not need to reference a concrete storage engine such as "mmfiles"
or "rocksdb"

* 'devel' of https://github.com/arangodb/arangodb:
Fixing index markers
exclusive locks for indexes
better incremental sync
grunt build
Avoid log spam.
Removed code paths that wrote objectIds into the Agency. This did break replication.
WAL: honor tick end value
WAL fiter after collection
Reactivated client-side filtering of unnecessary markers
Added an Assert when persisting an index it's objectId is not allowed to be 0
The RestReplicationHandler now inserts new ObjectIds when replicating collections
moved files
add dependencies for TransactionManager
fix include
move engine-specific test into engine test
* 'devel' of https://github.com/arangodb/arangodb:
Removed non-applicable test case.
unused variable
rocksdb options
fixes for non-array IN lookups, added tests
Add check for distributeShardsLike to dropCollectionCoordinator.
fixed foxx test
added missing return
js request simplified if sslProtocol
pass also sslProtocol from request to internal.download
fixed issue #2450
cppcheck
Added a missing switch break.
remove dead code
updated CHANGELOG
raised to 4
added 'x-content-type-options: nosniff' to avoid MSIE bug
fixed queue size
added queue size to statistics
added queue time and request tracing with timings
