Jiri Olsa	921f88fc89	bpf: Add size arg to build_id_parse function ... It's possible to have other build id types (other than default SHA1). Currently there's also ld support for MD5 build id. Adding size argument to build_id_parse function, that returns (if defined) size of the parsed build id, so we can recognize the build id type.

Jiri Olsa	bd7525dacd	bpf: Move stack_map_get_build_id into lib ... Moving stack_map_get_build_id into lib with declaration in linux/buildid.h header: int build_id_parse(struct vm_area_struct *vma, unsigned char *build_id); This function returns build id for given struct vm_area_struct. There is no functional change to stack_map_get_build_id function.
