[PATCH v2 2/7] pack-objects: pass "struct strvec *" instead of int/char ** pair

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

As in the preceding commit, prepare for the "nr" member of "struct
strvec" changing from an "int" to a "size_t".

In this case we end up passing the "nr" to setup_revisions(), which
expects to take an argc/argv pair passed to main(), so we can't change
its type.

But we can defer the conversion until that point. Let's continue to
pass the "struct strvec *" down into instead of "unwrapping" it in
cases where the only source of the "int/char **" pair is a "struct
strvec".
