Upstream version: 0.4.0, 96a2f23dca4
Local modifications:
* Added per-platform config.h files so no configuration-time
  checks for functions and so are needed.
* Added special definitions of HAVE_SNPRINTF and HAVE_LIB_GFLAGS
  in Windows' specific config.h.
* Silenced syscall deprecation warnings on macOS >= 10.12.
* Usage of syscall() is not allowed and use getthrid() to
  retreive the thread ID on OpenBSD
