Toke Høiland-Jørgensen 8ed35dc115 libbpf: Define BTF_KIND_* constants in btf.h to avoid compilation errors ... commit eaa266d83a upstream. The btf.h header included with libbpf contains inline helper functions to check for various BTF kinds. These helpers directly reference the BTF_KIND_* constants defined in the kernel header, and because the header file is included in user applications, this happens in the user application compile units. This presents a problem if a user application is compiled on a system with older kernel headers because the constants are not available. To avoid this, add #defines of the constants directly in btf.h before using them. Since the kernel header moved to an enum for BTF_KIND_*, the #defines can shadow the enum values without any errors, so we only need #ifndef guards for the constants that predates the conversion to enum. We group these so there's only one guard for groups of values that were added together.
