* fuzzers: mark whole input space in eff_map

* fuzzers: add undet bit threshold to skip some seeds

* fuzzers: fix one byte overflow

* fuzzers: fix overflow

* fix code format

* add havoc only again

* code format

* remove log to INTROSPECTION, rename skipdet module

* rename skipdet module

* remove log to stats

* clean redundant code
