Andrea has ported forkserver logic from afl++ https://github.com/AFLplusplus/LibAFL/blob/main/libafl_targets/src/forkserver.c

Our current forkserver example forksever_simple uses afl++'s compiler to instrument the program, but we want to make a forkserver example that uses libafl_cc + our forkserver logic in libafl_targets

Forkserver example with forkserver.c (#726) (#973)

* forkserver: Add an API to setup the shared memory region for edge coverage

This is inspired from and meant to be similar to afl-cc's instrumentation.
Remove ! return type from __afl_start_forkserver as it returns in several cases.

* Add example fuzzer using LibAFL's forkserver

The fuzzer is instrumented with libafl_cc as well.
