* Users can now use libbsd string.h and sys/cdefs.h functionality (e.g., strlcpy, containerof) on Linux by just including string.h or sys/cdefs.h. In other words, the includes are the same on the Linux target as well as on chips targets (ESP32, etc.). * libbsd linking is done by the linux component (belongs to common components) now instead of handling it separately in each component
