When bootloader spec is used to boot devices it is often desirable
to boot the same image from different media. Since the fs images
need to contain the root= parameters to tell Linux where to boot
from the images can't be identical on different media.
This patch changes this by introducing a 'appendroot' option for
bootloader spec. If set to true, barebox will construct a Linux
commandline option for the device the bootloader spec entry is found
on.

| ext4fs: fix "invalid extent block" error
|
| For files where we actually have extent indexes following
| an extent header (ext_block->eh_depth != 0), the do/while
| loop from ext4fs_get_extent_block() does not select the
| proper extent index structure.
|
| For example, if we have:
|
| ext_block->eh_depth = 1
| ext_block->eh_entries = 1
| fileblock = 0
| index[0].ei_block = 0
|
| the do/while loop will exit with i set to 0 and the
| ext4fs_get_extent_block() function will return 0, even if
| there was a valid extent index structure following the
| header.

Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
Compared to devfs_add_partition which adds a single partition
devfs_create_partitions creates several partitions at once. One nice
benefit is that this simplifies appending partitions because the start
of the latter partition doesn't need to be specified explicitly.
Also dev_add_bb_dev() is called by the new helper if the bbname is
specified for a partition.
Note that adding partitions is also more flexible now (also via
devfs_add_partition) because negative values for offset and size now
have a proper meaning instead of creating broken partitions.

Since this commit copy_file passes O_TRUNC to open(). This results in the
fs layer calling fsdrv->truncate. tftp returns -ENOSYS here and open returns
with an error. To fix this return 0 for the truncate callback in tftp. Also
enforce the O_TRUNC flag when opening a file for writing on tftp as the files
are always truncated on tftp anyway.
