  1. bpf: Add support for passing mark with bpf_fib_lookup 

    Extend the bpf_fib_lookup() helper by making it to utilize mark if
the BPF_FIB_LOOKUP_MARK flag is set. In order to pass the mark the
four bytes of struct bpf_fib_lookup are used, shared with the
output-only smac/dmac fields.

  2. selftests/bpf: Add BPF_FIB_LOOKUP_MARK tests 

    This patch extends the fib_lookup test suite by adding a few test
cases for each IP family to test the new BPF_FIB_LOOKUP_MARK flag
to the bpf_fib_lookup:

  * Test destination IP address selection with and without a mark
    and/or the BPF_FIB_LOOKUP_MARK flag set

  3. bpf: Add a check for struct bpf_fib_lookup size 

    The struct bpf_fib_lookup should not grow outside of its 64 bytes.
Add a static assert to validate this.

  4. bpf: improve error message for unsupported helper 

    BPF verifier emits "unknown func" message when given BPF program type
does not support BPF helper. This message may be confusing for users, as
important context that helper is unknown only to current program type is
not provided.

This patch changes message to "program of this type cannot use helper "
and aligns dependent code in libbpf and tests. Any suggestions on
improving/changing this message are welcome.

  5. bpf,arena: Use helper sizeof_field in struct accessors 

    Use the well defined helper sizeof_field() to calculate the size of a
struct member, instead of doing custom calculations.
