Detailed description
The objective is to merge the Chaff bugs into the main branch. The ideal is to have LAVA and Chaff bugs injected simultaneously. Here is the paper.

Note: I do NOT attempt to re-implement the heap-based overflows chaff bug, as this requires glibc 2.24, which uses a really old heap allocator and is therefore difficult to replicate. In a future PR, I will attempt to see if there is a generalized way, regardless of the heap allocator, to get this chaff bug.
...
Test plan
We should add tests where LAVA only injects chaff bugs and confirm that yes, it can't be exploited.
We should also confirm that both LAVA and Chaff bugs can be injected concurrently.
