Looks like mostly performance enhancements and stability fixes. The main
user facing changes appear to be:
- The -Z option was removed
- A macro named FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION is defined when
compiling with afl-gcc

Updating the QEMU patches
When updating to the latest American Fuzzy Lop, make sure to check for any new patches to qemu for binary fuzzing support:
https://github.com/mirrorer/afl/tree/master/qemu_mode
Be sure to check the build script and make sure it's also using the
right QEMU version and options in qemu.nix:
https://github.com/mirrorer/afl/blob/master/qemu_mode/build_qemu_support.sh
afl-config.h, afl-types.h, and afl-qemu-cpu-inl.h are part of
the afl source code, and copied from config.h, types.h and
afl-qemu-cpu-inl.h appropriately. These files and the QEMU patches
need to be slightly adjusted to fix their #includes (the patches
try to otherwise include files like ../../config.h which causes the
build to fail).
