[PATCH 0/5] refs: remove functions without ref store

Hi,

this patch series aims to convert the ref subsystem to rely less on `the_repository`. The focus of it is to remove those cases where we have two variants of the same function: one with a `struct ref_store`, and one without. There are still other cases in "refs.c" where we implicitly assume `the_repository`, but those require a bit more thought and will thus be handled in a subsequent patch series.

The biggest part of this patch is a set of new Coccinelle rules added by patch 3. Those rules are applied in patch 4 and the now-unused functions that do not take a `struct ref_store` are then removed in patch 5. This of course results in quite a lot of churn, but given that it is fully automated via Coccinelle I don't think it is particularly bad.

It is quite likely that this patch series will impact in-flight patch series. I'd be quite happy to drop the last patch that removes the old interfaces to make this a bit less painful.

Patrick Steinhardt (5):
  refs: introduce missing functions that accept a `struct ref_store`
  refs: add `exclude_patterns` parameter to `for_each_fullref_in()`
  cocci: introduce rules to transform "refs" to pass ref store
  cocci: apply rules to rewrite callers of "refs" interfaces
  refs: remove functions without ref store
