- fix buffer handling in libtraceevent
- add a missing pointer derefence in perf probe
- fix the build of host tools in cross builds
- fix Intel PT timestamp handling
- synchronize memcpy, cpufeatures and bpf headers with the kernel headers
- support for vendor supplied JSON files describing PMU events
- a new set of tool tips
- initial work for clang/llvm support
- address some style issues found by cppcheck
