bbu: Add a standard file-to-device-copy handler ...

The most standard update handler will simply copy a file to a device.
This can be shared across several users, so add a standard handler for
this operation.

This patch removes the const qualifier of the node argument from struct

blspec: Automatically append rootarg ...

This patch makes it possible to automatically add a suitable root= option
for booting Linux from the same filesystem on which the bootspec entry
has been found. This adds an additional 'linux-appendroot' option to
bootspec which if set to 'true' will cause barebox to automatically
add a root= option. This currently works for NFS, UBIFS and regular
block devices like ATA, SD/MMC using the root=PARTUUID= mechanism.

blspec: Automatically attach UBI devices ...

When blspec_scan_cdev finds an UBI device then attach it. This
allows us to boot blspec entries found on the UBIFS images inside
UBI volumes by pointing to the corresponding mtd partition.
With this we can do 'boot nand0.root' or even 'boot=nand0' on the
commandline.

imx-bbu-nand-fcb: Split space for firmware in two equal regions ...

We used to write the second firmware right after the first
firmware. However, splitting the available space into two
equal regions has advantages: When we update barebox the next
time the generated FCB/DBBT blocks will be the same as with the
last update, so in case of power failure it is more likely that
we have valid data in one of the FCB/DBBT areas.

imx-bbu-nand-fcb: Erase whole partition ...

Now that we use a partition for the bootloader instead of

imx-bbu-nand-fcb: Let DBBT start at page 1 ...

We used to put the FCB in the first two NAND blocks and the DBBT
in the third and fourth block. It's much more space efficient to
put the FCB and DBBT together into the same eraseblock in different
pages. This way we can store four FCBs and four DBBTs instead of
two only.

imx-bbu-nand-fcb: Use barebox partition instead of whole device ...

We used to use nand0 device for storing barebox and made the assumption
that there is enough space at the beginning of the first device. Instead,
use the barebox partition directly. This requires that the partition
where barebox should be stored is named 'barebox', that is the case for
all boards currently.
