tmp-objdir: new API for creating temporary writable databases
The tmp_objdir API provides the ability to create temporary object directories, but was designed with the goal of having subprocesses access these object stores, followed by the main process migrating objects from it to the main object store or just deleting it. The subprocesses would view it as their primary datastore and write to it. Here we add the tmp_objdir_replace_primary_odb function that replaces the current process's writable "main" object directory with the specified one. The previous main object directory is restored in either tmp_objdir_migrate or tmp_objdir_destroy. For the --remerge-diff usecase, add a new `will_destroy` flag in `struct object_database` to mark ephemeral object databases that do not require fsync durability. Add 'git prune' support for removing temporary object databases, and make sure that they have a name starting with tmp_ and containing an operation-specific name.
