Introduce AFL_DEBUG_UNICORN and document logging #17

Closed mariusmue closed 2 years ago

mariusmue commented 2 years ago

As of now, AFL_DEBUG_CHILD enables unicorn debugging messages in the child process. If one uses debug prints in the unicorn harness, this may easily lead to confusion, as a lot of messages about translations would be printed as well.

This PR adds an additional AFL_DEBUG_UNICORN env variable to toggle whether this translation output shall be printed as well, or not. Probably, minor changes to AFL++ are needed as well, to surpress:

[!] WARNING: Mistyped AFL environment variable: AFL_DEBUG_UNICORN=1
Did you mean AFL_DEBUG?

Besides this, I also added some documentation about this logging differences in the README.md

I can easily make the changes in afl++ if @domenukk is happy with this
