* Add support for Alexey Tourbin's QSORT code
See https://github.com/svpv/qsort
* Add benchmark scripts and compilation mode
Compile with `make O_BENCHMARK=1`, and run benchmarks with e.g.:
./misc/test/benchmark.sh ./nnn '/' '/usr/bin' '/usr/lib' > benchdata
You can then plot basic violin graphs with:
./misc/test/plot-bench.py benchdata
* Update style, doc, haiku support, fix lint
