master
build: Refactor `make clean` and `make coverage` targets (do a per-dir cleanups, not a single global one from the top directory)
tests: added combined tests, which test Snoopy as a whole
tests: Stop manually parsing output of `id -a`, instead use the appropriate flags to get desired output
tests: Convert `readlink` usage to Busybox-compatible one (change `-e` to `-f`)
