Now that expire_reflog() doesn't actually look in the
expire_reflog_policy_cb data structure, we can make it opaque:
* Change the callers of expire_reflog() to pass it a pointer to an
entire "struct expire_reflog_policy_cb" rather than a pointer to a
"struct cmd_reflog_expire_cb".
* Change expire_reflog() to accept the argument as a "void *" and
simply pass it through to the policy functions.
* Change the policy functions, reflog_expiry_prepare(),
reflog_expiry_cleanup(), and should_expire_reflog_ent(), to accept
"void *cb_data" arguments and cast them back to "struct
expire_reflog_policy_cb" internally.
