This patchset is based on Arnaldo's perf/core. Patch 1/5 - 2/5 improve BPF related error delivering and reporting. Libbpf and bpf-loader define their own error code sets so can deliever precise reason of failure. Corresponding strerror functions are improved accordingly.
Patch 3/5 - 5/5 improve 'perf test LLVM' and 'perf test BPF'. Code structure improved so new test case can be introduced easier.
