[PATCH 2/3] list-object-filter: pass traversal_context in filter_init_fn

["ZheNing Hu via GitGitGadget" <gitgitgadget@gmail.com>]

From: ZheNing Hu <adlternative@gmail.com>

Pass traversal_context to all filter init functions, so that
we can read or modify the rev_info of traversal_context in the
filter initialization function.
