Yonghong Song c0ac48783c bpf: Refactor to provide aux info to bpf_iter_init_seq_priv_t 
[upstream commit f9c792729581bd8b8473af163e8ab426c2c61d89]

This patch refactored target bpf_iter_init_seq_priv_t callback
function to accept additional information. This will be needed
in later patches for map element targets since a particular
map should be passed to traverse elements for that particular
map. In the future, other information may be passed to target
as well, e.g., pid, cgroup id, etc. to customize the iterator.
