Subject: [PATCH 1/2] fast-export: make extra_refs global
There's no need to pass it around everywhere. This would make easier
further refactoring that makes use of this variable.

Subject: [PATCH 2/2] fast-export: refactor get_tags_and_duplicates()
Split into a separate helper function get_commit() so that the part that
finds the relevant commit, and the part that does something with it
(handle tag object, etc.) are in different places.
No functional changes.
