UBI fastmap updates

[Richard Weinberger]

This is the next round of UBI fastmap updates.

Fastmap is now disabled by default.
If you attach an image it will not automatically convert it
to the fastmap format.
UBI has a new module parameter "fm_auto".
If set to 1 UBI will create a fastmap automatically on your
flash device.
Please see commit "Add a module parameter to enable fastmap"
for more details.

If you want to test fastmap you can use my git repo:
git://git.kernel.org/pub/scm/linux/kernel/git/rw/ubi2.git ubi2/v15

Enjoy!
