these are (for now) permanent ones:

          - aflplusplus_cmplog
          - aflplusplus_mopt
          - aflplusplus_mopt_cmplog

these are one off: (but aflplusplus should not be deleted, it is the master that is included)

          - aflplusplus
          - aflplusplus_ctx
          - aflplusplus_ctx_mmopt

I hope Andrea's fuzzer.py works correctly ...

Lets hold on this, we have support for fuzzer configurations in #231 and planning to add build side hooks soon too.

as this is a one time thing, and I would not like to hold on to this but rather have that run after the current one (thats what @jonathanmetzman wanted to do).
This run is a building block for our upcoming work, so we wait for these result ...

Switch to #225 as this PR is included in it. @vanhauser-thc close it, presubmit is broken.

[aflplusplus] Fix target compilation, we had 10%+ speed loss ... (#377)
64c96ee 
* Remove dislocator from AFL++

One of the possible reasons of the decrement in performance of AFL++ in the lastest report is due to the missing AFL_ALIGNED_ALLOC env var. Without this variable, dislocator's malloc does not ensure that the returned address is aligned to max_aligned_t (as required by posix) but it is able, in this way, to catch more bugs.
Many applications checks for this alignment and this may cause an early exit in the application (and so a low coverage).
I completely remove dislocator to better understand what is happening in the next run of the experiments.
