[PATCH v4 0/4] advice: remove usage of `advice_*` global variables

I reviewed Ben Boeckel's advice() patches in https://lore.kernel.org/git/RFC-cover-v3-0.4-0000000000-20210806T191231Z-avarab@gmail.com and submitted that review as an RFC. Since there's been no feedback there from the author here's a non-RFC version.

The only change from v3 is the commit message typos/grammar fixes pointed out by Eric Sunshine. Thanks!

Ben Boeckel (2):
  advice: add enum variants for missing advice variables
  advice: remove read uses of most global `advice_` variables

Ævar Arnfjörð Bjarmason (2):
  advice: remove use of global advice_add_embedded_repo
  advice: move advice.graftFileDeprecated squashing to commit.[ch]

    @@ Commit message
         This patch ports all but two uses which read the status of the global
         `advice_` variables over to the new `advice_enabled` API. We'll deal
         with advice_add_embedded_repo and advice_graft_file_deprecated
    -    seperately.
    +    separately.
