Summary: Depends on D19138. Ref T13088. When we want to read the last part of a logfile //and show accurate line numbers//, we need to be able to get from byte offsets to line numbers somehow. Our fundamental unit must remain byte offsets, because a test can emit an arbitrarily long line, and we should accommodate it cleanly if a test emits 2GB of the letter "A". To support going from byte offsets to line numbers, compute a map with periodic line markers throughout the offsets of the file. From here, we can figure out the line numbers for arbitrary positions in the file with only a constant amount of work. Test Plan: Added unit tests; ran unit tests.
