Patch 1 fixes an issue when using drastically different BPF map definitions inside ELFs from a client using libbpf, vs the map definition libbpf uses. Patch 2 is a trivial typo fix. Patches 3-5 add some simple, useful helper functions for setting prog type and retrieving libbpf errors without depending on kernel headers from userspace programs. Patch 6 adds a new pinning functionality for an entire object. Calling bpf_object__pin(obj, subpath) will mount all programs from the BPF object to $bpf_fs_path/$subpath/progs/$progname, and all maps from the BPF object to $bpf_fs_path/$subpath/maps/$mapname. The first program with a particular name will be mounted with its progname and the suffix "_0"; subsequent programs with the same will have "_1", and so on; duplicate maps with the same name are disallowed.
