eeea3ea6a8 genext2fs.sh: improve number of blocks calculation
Closes #2929

Instead of just adding a fixed amount to the blocks used, try to
estimate the real space needed according to the filesystem structure
(bitmaps, inodes, blocks).

The side effect of this is that we no longer significantly overestimate
the size needed for small file systems.

32a8c0119f Add network scripting folders to fs/skeleton
Those folders are currently created using makedevs according to the
specifications in device_table.txt. However, as makedevs is no longer
executed when dynamic device creation methods are selected (devtmpfs,
udev, mdev), those folders must be created differently. We choose to
put them directly into the default filesystem skeleton.

This used to be needed when the filesystem code was rewritten, but not
the Linux compilation code. Now that the Linux compilation code has
been rewritten, the mechanism to ensure that initramfs gets built
*before* the kernel so that it can be integrated is different, and
this INITRAMFS_TARGET variable is no longer used.

f507921d39 linux: add support for initramfs
In Buildroot, the kernel is built and installed *before* the root
filesystems are built. This allows the root filesystem to correctly
contain the kernel modules that have been installed.

However, in the initramfs case, the root filesystem is part of the
kernel. Therefore, the kernel should be built *after* the root
filesystem (which, in the initramfs case simply builds a text file
listing all files/directories/devices/symlinks that should be part of
the initramfs). However, this isn't possible as the initramfs text
file would lack all kernel modules.

So, the solution choosen here is to keep the normal order: kernel is
built before the root filesystem is generated, and to add a little
quirk to retrigger a kernel compilation after the root filesystem
generation.

To do so, we add a ROOTFS_$(FSTYPE)_POST_TARGETS variable to the
fs/common.mk infrastructure. This allows individual filesystems to set
a target name that we should depend on *after* generating the root
filesystem itself (contrary to normal ROOTFS_$(FSTYPE)_DEPENDENCIES,
on which we depend *before* generating the root filesystem).

The initramfs code in fs/initramfs/initramfs.mk uses this to add a
dependency on 'linux26-rebuild-with-initramfs'.

In linux/linux.mk, we do various things :

 * If BR2_TARGET_ROOTFS_INITRAMFS is enabled (i.e if initramfs is
   enabled as a root filesystem type), then we create an empty
   rootfs.initramfs file (remember that at this point, the root
   filesystem hasn't been generated) and we adjust the kernel
   configuration to include an initramfs. Of course, in the initial
   kernel build, this initramfs will be empty.

 * In the linux26-rebuild-with-initramfs target, we retrigger a
   compilation of the kernel image, after removing the initramfs in
   the kernel sources to make sure it gets properly rebuilt (we've
   experienced cases were modifying the rootfs.initramfs file wouldn't
   retrigger the generation of the initramfs at the kernel level).

This is fairly quirky, but initramfs really is a special case, so in
one way or another, we need a little quirk to solve its specialness.

3754c51560 jffs2: let makedevs create device files
The common filesystem infrastructure in fs/common.mk uses a smart
combination of makedevs and fakeroot to create the device files in the
target filesystem images without being root. This technique is applied
to all filesystem formats that rely on this common infrastructure, and
JFFS2 is one of them.

Therefore, using the -D option of mkfs.jffs2, which allows to specify
a device table, is redundant with the usage of makedevs. And it is
worst than redundant: for some reason, -D does not create all device
files with the correct major and minor numbers, as reported in
bug #1771.

For coherence, we just remove the usage of mkfs.jffs2 -D option, and
rely on makedevs/fakeroot to create the device files.

This commit fixes bug #1771.

fb951b9342 fs/ext2: fix blocks/inodes calculation
With the ROOTFS_TARGET conversion, EXT2_OPTS gets evaluated very early
(before TARGET_DIR is populated with files), so the calculated
blocks/inodes numbers are wrong.

Fix it by moving the calculation to a shell script wrapper around
genext2fs, so it only gets executed just before genext2fs runs.

64ec20e6c0 fs: change the way the device table is configured
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.
