pack-revindex: make load_pack_revindex take a repository

Browse Source 
In a future commit, we will introduce a `pack.readReverseIndex`
configuration, which forces Git to generate the reverse index from
scratch instead of loading it from disk.

In order to avoid reading this configuration value more than once, we'll
use the `repo_settings` struct to lazily load this value.

In order to access the `struct repo_settings`, add a repository argument
to `load_pack_revindex`, and update all callers to pass the correct
instance (in all cases, `the_repository`).

In certain instances, a new function-local variable is introduced to
take the place of a `struct repository *` argument to the function
itself to avoid propagating the new parameter even further throughout
the tree.
