Diff to previous 1.13 (colored)

rewrite to not use mmap(2). solves a bunch of issues:
- No more I/O related SEGVs (PR 2337?).
- Performance linear to size of output, not input file size, even for very large files.
  Same for -r.
- Reverse tail also works for very large files.
- Very large values of n possible, even for very large files. Same for -r.
