* fix buffer overruns in linenoise for long input lines
* don't make historian repeatedly print the same error messages that nothing can be done about
* make the implementations of the logging operator<<s not throw exceptions, so that logging does throw exceptions as an unintended side effect
* update CHANGELOG
* improve error message
* don't copy strings, but pass them by const reference
* extend linenoise character buffer size
* dont make it throw exceptions all the time
* set INSTANCE to nullptr at a later stage
otherwise a nullptr may be accessed during shutdown
* 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
* reuse string from ManagedDocumentResult for multiple lookups
* use move-assign
* a bit less work for single server
* speedup AQL function HASH
* single fetch optimization
* performance optimization for the case when no documents need to be returned
* make reduce-extraction-to-projection a RocksDB-only optimizer rule
* cppcheck
* try to fix compile error on MacOS
* bug fix for MacOSX
* missing namespace (in Windows compile)

* Allocate scratch space in BlockCipher, used for all subsequent calls to EncryptBlock
* Adding more enterprise hooks
* Added encryption test script
* Added (commented) entry for encryption-keyfile
* Use correct env
* Updated ARANGODB value
* Log startup at debug level
* Removed TTY flag
* Fixed build
* Added prefix block support with unique initial counter & IV for CTR implementation
