pack-bitmap[-write]: use `object_array_clear()`, don't leak

Instead of setting the fields of rev->pending to 0/NULL, thereby leaking
memory, call `object_array_clear(&rev->pending)`.

In pack-bitmap.c, we make copies of those fields as `pending_nr` and
`pending_e`. We never update the aliases and the original fields never
change, so the aliases are not really needed and just make it harder
than necessary to understand the code. While we're here, remove the
aliases to make the code easier to follow.
