Implements pthreads based du using FTS. Currently 4 threads are used.
NFTW is dropped as there is no way to pass any custom values to fn().
FTS does not require any per entry function callback.
The performance numbers are best with FTS:

* 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
* Add icons
* Fix build break
* Fix icon position in detailed mode
* Various fixes
* Provision for icon specific colors
No icons with oldcolor. Small optimizatons
* Update Makefiles
Small refinement for other matching
* Add an option to print hovered files to a FIFO
This adds an env variable, `NNN_FIFO`, that can be set to a path that
`nnn` will open/create as a FIFO, and where every hovered file's path is
printed. This allows creating external perview/quick open plugins, ...
It can be compiled out with the make variable `O_NOFIFO`.
* Check filename ptr instead of full path (for FIFO)
* Add documentation to use NNN_FIFO in plugins
* Fix path sent to FIFO in empty dirs
* Don't pack sources (github does it better), sign sources
* Make CircleCI generate the same git archive as Github, return make dist
* Revert make clean too
* Upload signature to Github release
* Read Github token from an env variable
