[PATCH 1/2] sequencer: teach autostash apply to report conflicts
From: Harald Nordgren via GitGitGadget <hidden>

From: Harald Nordgren <redacted> Add a conflicted parameter to apply_save_autostash_oid() and apply_save_autostash_ref() so callers can learn whether applying the stash resulted in conflicts. Thread the parameter through apply_autostash_ref() and update existing callers to pass NULL.
