Changes the naming from "scan" to "node" in the pose graph.
AddNode() adds a new node to the graph which might contain
data from multiple range sensors and not necessarily one scan.
Configuration and documentation changes might follow in a
separate PR.
Related to #280.

- Pin versions of Ceres and protobuf (Fixes#341).
- Require Lua >= 5.2 (Fixes#629).
- No longer run ceres tests in CI. We implicitly test Ceres through Cartographer's tests and this saves ~4 minutes on CI.
This adds information about which nodes are contained in which
deserialized submaps. This is necessary for the rotational scan
matcher.
Also skips frozen trajectories when tying together nodes of a
trajectory with IMU data which is unavailable in this case.
- introduce InsertIntoSubmap for 2D
- clarify some variable names in 3D
- move rotational_scan_matcher_histogram calculation
to InsertIntoSubmap for 3D
- refactor last version of range data before insertion into
range_data_in_local (filtered_range_data_in_local for 3D)
This changes the origin of accumulated range data from the
zero vector (which could be far off) to the origin of the
first range data in the accumulation.
Adds a type TimedPointCloud that holds 4-dimensional vectors where measurement time of individual points are stored in the fourth entry.
Uses TimedRangeData to pass TimedPointCloud of incoming measurements to LocalTrajectoryBuilder.
Fixes#573.
This speeds up the asset writer significantly:

So ~10%. For pipelines that do less this can be even 30% or more.
