[PATCH] busybox 1.6.0 : command history on read-only rootfs like cramfs.

[GeunSik Lim]

Hi All,

This patch will support command history on read-only rootfs like
cramfs, squashfs.
Please, Use Ctrl+N/P or UP/Down key for command history.

For reference, If you have rewritables filesystem like ext2/3/4, you can
utilize /.ash_history file in your embedded rootfs like previously.

* Test result of memory history on readonly rootfs
