This patch makes it possible to format the rootfs using btrfs. It
introduces the option; BR2_TARGET_ROOTFS_BTRFS.
When selected, the user is able to specify the filesystem size, label,
options, and node and sector sizes. The new files are based on
fs/ext2/{Config.in,ext2.mk}

[Thomas:
- fix issues pointed by Yann (duplicated empty line, missing quotes
around default values for string options)
- use -f option so that we don't have to remove the image file before
creating it again
- use the --byte-count option to set the filesystem size, which
avoids the need for doing a "truncate -s"
- remove the possible explanation of a mkfs.btrfs error. Indeed,
mkfs.btrfs automatically extends the size of the image as needed,
so the size passed can never be "too small".
- fix check-package warnings in Config.in file.]

Currently, the ubifs-in-ubi-image ("UBI image" thereafter) filesystem
is half an option of the ubifs filesystem, half a filesystem on its
own: the config options are options of the ubifs filesystem, but the
.mk code is in a separate .mk and registers a real filesystem.
Make it a full filesystem on its own, in its own directory tree.

The Advanced XIP File System is a Linux kernel filesystem driver that
enables files to be executed directly from flash or ROM memory rather
than being copied into RAM. It has the ability to store individual
*pages* in a file uncompressed/XIP or compressed/Demand Paged.
This commit only adds support for 'XIP all' mode, so all the files that
have the execute attribute set will be XIP'ed.
At the moment, the FS is not supported in Linux mainline (v4.3-rc5), so
the kernel has to be built with the axfs patches to be able to read it.

Instead of the current mix between system config and filesystem menus.
At the same time rename 'Target filesystem options' menu to
'Filesystem images' as it now only contains options about image formats.

This allows to have a device table for all directories/files and
another device table for the device files themselves. Both are needed
for static /dev, but only the first one is needed when
devtmpfs/mdev/udev are used.
We take this opportunity to move the documentation of the device table
format in a common location, package/makedevs/README.
[Peter: simplify code slightly, fix indentation]

Four methods for the creation of device files in /dev are now
proposed:
- static method uses device table as before
- devtmpfs method enables this feature in kernel
- mdev method adds mdev starting script to the file system
and selects mdev itself for installation
- udev method selects udev for installation
All dynamic methods are based on devtmpfs, so one doesn't need to care
about /dev folder.

Until now, the location of the device table was specified by a
variable in board Makefiles. Unfortunately, this variable is not
accessible from fs/common.mk, since the target/ code is included
*after* fs/common.mk.
Anyway, the general idea is to move away from these boards Makefile,
and provide configuration option for things like the device table
location.
Therefore, this patch adds a BR2_ROOTFS_DEVICE_TABLE option which
allows to specify which device table should be used.
