[PATCH 0/2] ns/tmp-objdir: add support for temporary writable databases

New interface into the tmp-objdir API to help in-core use of the quarantine
feature.

This patch series was formerly part of the ns/batched-fsync topic [1]. It's
now split out into its own gitgitgadget PR and discussion thread since it is
the base for en/remerge-diff as well.

The most recent feedback was in [2]. I removed printing from prune_subdir
and simplified the strbuf handling in prune_tmp_file.
