/*
* This API allows you to create a temporary object directory, advertise it to
* sub-processes via GIT_OBJECT_DIRECTORY and GIT_ALTERNATE_OBJECT_DIRECTORIES,
* and then either migrate its object into the main object directory, or remove
* it. The library handles unexpected signal/exit death by cleaning up the
* temporary directory.
*
* Example:
*
* struct tmp_objdir *t = tmp_objdir_create();
* if (!run_command_v_opt_cd_env(cmd, 0, NULL, tmp_objdir_env(t)) &&
* !tmp_objdir_migrate(t))
* printf("success!\n");
* else
* die("failed...tmp_objdir will clean up for us");
