Update tools/lib/bpf to provide the remaining bpf wrapper pieces needed by the samples/bpf/ code, then get rid of all of the duplicate BPF libraries in samples/bpf/libbpf.[ch].
--- v5: Fixed prog_size vs. instruction count API difference in bpf_load_program() REBASE: Rebased v3 that was applied to perf/core. Resolved merge conflict with net-next. New patch shifts bpf_prog_{attach,detach}() to libbpf. Drop unnecessary build targets Drop extra unneeded log buffers v3: Add ack for first patch. Split out second patch from v2 into separate changes for remaining diff. Add patches to switch samples/bpf over to using tools/lib/. (Was "libbpf: Synchronize implementations") v2: Don't shift non-bpf code into libbpf. Drop the patch to synchronize ELF definitions with tc. v1: https://www.mail-archive.com/netdev@vger.kernel.org/msg135088.html First post.
