tools/bpf: expose functions btf_ext__* as API functions
The following set of functions, which manipulates .BTF.ext
section, are exposed as API functions:
. btf_ext__new
. btf_ext__free
. btf_ext__reloc_func_info
. btf_ext__reloc_line_info
. btf_ext__func_info_rec_size
. btf_ext__line_info_rec_size
These functions are useful for JIT based bpf codegen, e.g.,
bcc, to manipulate in-memory .BTF.ext sections.
The signature of function btf_ext__reloc_func_info()
is also changed to be the same as its definition in btf.c.
