[bpf] add BPF disassembler add BPF disassembler, so tools like llvm-objdump can be used: $ llvm-objdump -d -no-show-raw-insn ./sockex1_kern.o ./sockex1_kern.o: file format ELF64-BPF Disassembly of section socket1: bpf_prog1: 0: r6 = r1 8: r0 = (u8 )skb[23] 10: (u32 )(r10 - 4) = r0 18: r1 = (u32 )(r6 + 4) 20: if r1 != 4 goto 8 28: r2 = r10 30: r2 += -4 ld_imm64 (the only 16-byte insn) and special ld_abs/ld_ind instructions had to be treated in a special way. The decoders for the rest of the insns are automatically generated. Add tests to cover new functionality.
