* Simplified and improved hfuzz_cc compiler
* More string instrumentation in libhfuzz
* Android: works with Android-NDK 15 and newer only
* Dockerfile
* Refreshed docs
* Linux: Faster BTS/PT due to less PMU state resets
* Linux: tests and by-pass for the Linux' fork-when-multithreaded
problem
* libFuzzer/AFL style dictionaries
* Runnable under docker/oss-fuzz
- Changes for version 1.0:
* Multiple stability improvements for most of the supported
architectures
* More examples in examples/ (e.g. Linux kernel IP for BTS/PT)
* Documentation updates
