[PATCH 2/5] pack-objects: move revs out of get_object_list()

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <derrickstolee@github.com>

We intend to parse the --filter option directly into revs.filter, but we
first need to move the 'revs' variable out of get_object_list() and pass
it as a pointer instead. This change only deals with the issues of
making that work.
