TODO list for AFL++

Should

support afl_custom_{send,post_process}, persistent and deferred fork server in afl-showmap
better autodetection of shifting runtime timeout values
Update afl->pending_not_fuzzed for MOpt
afl-plot to support multiple plot_data
parallel builds for source-only targets
get rid of check_binary, replace with more forkserver communication
first fuzzer should be a main automatically

Maybe

forkserver tells afl-fuzz if cmplog is supported and if so enable it by default, with AFL_CMPLOG_NO=1 (?) set to skip?
afl_custom_fuzz_splice_optin()
afl_custom_splice()
cmdline option from-to range for mutations

Further down the road

QEMU mode/FRIDA mode:

non colliding instrumentation
rename qemu specific envs to AFL_QEMU (AFL_ENTRYPOINT, AFL_CODE_START/END, AFL_COMPCOV_LEVEL?)
add AFL_QEMU_EXITPOINT (maybe multiple?), maybe pointless as there is persistent mode

Ideas

LTO/sancov: write current edge to prev_loc and use that information when using cmplog or __sanitizer_cov_trace_cmp*. maybe we can deduct by follow up edge numbers that both following cmp paths have been found and then disable working on this edge id -> cmplog_intelligence branch
use cmplog colorization taint result for havoc locations?
