remote: move static variables into per-repository struct

remote.c does not works with non-the_repository because it stores its
state as static variables. To support non-the_repository, we can use a
per-repository struct for the remotes subsystem.

Prepare for this change by defining a struct remote_state that holds
the remotes subsystem state and move the static variables of remote.c
into the_repository->remote_state.

This introduces no behavioral or API changes.
