    Use make_tempname file descriptor in smart_rename

    This patch makes use of the temp file descriptor in smart_rename
    rather than reopening the file.  I don't believe there is a security
    issue in reopening the file, but this way is one less directory
    operation.  The patch also attempts to preserve S_ISUID and S_ISGID.

            PR 27456
            * bucomm.h (smart_rename): Update prototype.
            * rename.c (smart_rename): Add fromfd and preserve_dates params.
            Pass fromfd and target_stat to simple_copy.  Call set_times
            when preserve_dates.
            (simple_copy): Accept fromfd rather than from filename.  Add
            target_stat param.  Rewind fromfd rather than opening.  Open
            "to" file without O_CREAT.  Try to preserve S_ISUID and S_ISGID.
            * ar.c (write_archive): Rename ofd to tmpfd.  Dup tmpfd before
            closing output temp file, and pass tmpfd to smart_rename.
            * arsup.c (temp_fd): Rename from real_fd.
            (ar_save): Dup temp_fd and pass to smart_rename.
            * objcopy.c (strip_main, copy_main): Likewise, and pass
            preserve_dates.
