[PATCH 2/2] Add --stage to show-files for new stage dircache.

[Junio C Hamano]

This adds --stage option to show-files command.  It shows
file-mode, SHA1, stage and pathname.  Record separator follows
the usual convention of -z option as before.

The patch is on top of the byte order fix for create_ce_flags in my
previous message.
