Summary:
All external libraries now automatically include their include directories. It
is necessary only to link to the external library using
`target_link_libraries(target library)` and the include directory of the
library will be automatically available for the binary.

Summary:
The long running stress test had a subtle race condition which caused the test
to fail with an error message like "Runner X edges creation failed because of:
Can't serialize due to concurrent operations.". This situation was caused
because some workers could complete their initialization (initial vertex and
edge creation) before other workers. The workers that completed their
initialization would then proceed to execute the test. In the test they could
execute queries that make global updates on the graph that could interfere with
the concurrently running initialization queries of other workers.
This diff makes the runners wait until all initialization queries are fully
executed before they execute global operations on the graph.

Summary:
The test is now more strict than before. Each verification step doesn't just
verify that object counts are correct, it now also verifies that all object IDs
are correct. The continuous integration script is improved to have a more
deterministic startup.

Summary:
The property store stores a map of `PropertyId` to `PropertyValue` mappings. It
compresses all of the values in order to use as little memory as possible.

Summary:
Don't use flag files for specifying flag values in tests. Instead, all
necessary flags are explicitly defined in each of the tests.

Summary:
Edge filters (edge type and destination vertex) are now handled natively in the
storage API. The API is implemented to be the fastest possible when using the
filters with the assumption that the number of edge types will be small.

Summary:
The query execution now has a timeout for each Cypher query it executes. The
timeout is implemented using TSC and will work only when TSC is available (same
as PROFILE). TSC is used to mitigate the performance impact of reading the
current time constantly.

Now when iterating over a label+property index the index verifies that the
bounds meet the criteria imposed by openCypher.

Summary:
Previously, when accessing the labels/properties/edges of a vertex/edge that
was just created the NEW view would correctly display the change, but the OLD
view would be invalid and would crash the database. With this change the OLD
view of a freshly created vertex/edge won't cause a crash, but will instead
report an error.
