updated to use the repository-aware variants.
* rs/tempfile-wo-the-repository:
use repo_hold_lock_file_for_update{,_mode,_timeout}() with custom repos
tempfile: stop using the_repository
lockfile: add repo_hold_lock_file_for_update{,_timeout}{,_mode}()
refs/packed: use repo_create_tempfile()
tempfile: add repo_create_tempfile{,_mode}()
