[PATCH] Split of raid scan code

[Bean]

Hi,

This patch seperate the scan code from raid.c, and move it to
mdraid.c. raid.c only contain generic raid handling code now. This
make it much easier to extend to other raid layout, like various
fakeraids.

I also extend the function of grub-fstest so that it can be used to
debug raid, for example, you can run it like this:

grub-fstest -c 2 /dev/hdb1 /dev/hdd1 ls
