ARROW-3404: [C++] Make CSV chunker faster This speeds up multi-threaded CSV reads by removing the serial bottleneck of detecting newlines when no newlines can be present in CSV values. On this machine (8-core AMD processor), the speed of reading a CSV file of text column data goes from 600 MB/s (before this patch) to 1.2 GB/s. Author: Antoine Pitrou <antoine@python.org> Closes #2684 from pitrou/ARROW-3404-faster-csv-chunker and squashes the following commits: 549ef20c5 <Antoine Pitrou> ARROW-3404: Make CSV chunker faster
